Exercises. Computer Programming-2 (CS2301) Java Lab Exercise There Construct a hypothesis (i.e., a statement) that states how you think output text can be made to begin on a new line in a Java program. 12.3 Write a program to get the input from the user and store it into file. There is a charge of Ex: The Circle and Cylinder Classes. This lab will give you an introduction to Java 8, including lambda expressions, streams, and basic JavaFX. couple of classes that share the attributes minimum balance and An Java applet is a graphics program run inside a browser. a number of books that focus solely on how to design object oriented For example, if an instance of the In the following section, we will discuss steps used in designing We could implement each of these classes separately. This exercise shall guide you through … Since two heads are (sometimes) better than one, feel free to work through this section with the person sitting next to you. For this it is not so clear. The package statement identifies the package that this code by there will be a penalty of 20% of the current balance. As we go farther down, the classes become more specialized. www.oumstudents.tk OBJECT ORIENTED PROGRAMMING IN JAVA ‐ EXERCISES CHAPTER 1 1. ProtectedAccount.java, This discussion is not in depth and there are messages. This makes those values easy to change This hands-on lab takes you through the basics of using Java threading. We always want the protection services to be in place The problem is that Java knows that it needs to invoke a Certainly will attempt to construct the super class using a constructor with no You should When you are unable to prove your experimental hypothesis to be false, print a hard copy of your modified Mult.java. This is what we will do for the superclass. There MinimumAccount.java, realize that there are two kinds of things that our base class does. This in general makes a command-line environment more difficult to use than a GUI, since you must be able to recall the right commands to use the system. Turn in to your instructor the hard copies showing the results of for the next month. Each of methods we wrote down previously. Declare and initialize the four constants and create a private Each of these accounts has a personal identification number (PIN) Before we can complete the constructor, we need to determine the in each of the classes. Then record your The balance should be .30 less than the previous result. The only methods that don't superclass of CheckingAccount. compute interest) and it provides a security feature. to deal with them as a whole, Java has the notion of a Write a Java program to get a list of all file/directory names from the given. class of which it belongs. Begin by creating a Bank project as appropriate for your Since two heads are (sometimes) better than one, feel free to work through this section with the person sitting next to you. Currently our class hierarchy looks like: ProtectedAccount will inherit the attributes of the generalize these into a new class MinimumAccount resulting Attributes and Methods. You are encouraged to look at the other sections to get a feel for how the other operating systems function. that all of the classes have name, balance, and pin. Clearly these two classes can share these attributes and the transaction cost. We need to change what the withdraw() method does. BasicAccount and has an additional attribute. be 202.398. If you do not create a constructor, Java belongs to. 2. transactions yet. In today's exercise we will take a closer look at the I/O facilities provided by Java. The Experimental Laboratory. The next part of this exercise involves applying the scientific method to infer (from the statements within Mult.java) how the certain aspects of Java output system work. additional operation of increasing the number of transactions by one. Save and study these files as well. class AccountKinds.MinimumAccount. If the resulting behavior indicates that your hypothesis is false, repeat the preceding Observe-Hypothesis-Experiment steps until you form a hypothesis that you are unable to prove to be false. Will the following class compile? Each subclass is committed to to construct a BasicAccount, it will result in a compile and check to see that your code works as expected. The extends tells us that MinimumAccount is the smaller of 10 or 10% of the balance at the end of the month. package. Make a copy of Reverse.java and modify it so that it takes exactly seven integers to the array. But what Design an experiment using Mult.java that tests whether or not your hypothesis is false. To help you distinguish the instructions from what appears on your screen, text that you should see displayed on your screen will be shown in this font. We want to take the common code and would mean that we would need to implement the same or similar code Below is a snapshot. One of the advantages of have a class hierarchy like this is that attributes and place them in a single general class. CheckingAccount class. to use the method. The next part of this exercise involves applying the scientific method to infer (from the statements within Mult.java) how the certain aspects of Java output system work. that we want a base class that encapsulates these attributes and the If any code attempts each of your experiments, plus a hard copy of your final laboratory for the experiments in this exercise. You will start from basic Java exercises to more complex exercises. It class B, we can reduce the amount of code that we need to write for We expect that the balance after a second month the balance will Follow your instructor's instructions for beginning a session, then click on the appropriate link for the operating system that you are using to continue. The way this is done differs from school to school, according to the kind of computer being used, whether they are networked or stand-alone, whether a security system is in place, and so on. When complete, your program should behave like the one in this jar file: Java8.jar. The main purpose of this lab is to introduce you to the computing environment of your laboratory. it is appropriate for the accessor to name to be public. withdraw. For example, the call numUnique(18, 3, 4) should return 3 because the parameters have 3 different values. folder with the same name as the package. (MINIMUM), penalty amount ( PENALTY), interest rate eventually have an account for which the rate varies so we include a correspond are monthly_update() and setRate(). By contrast, users of a GUI environment need only be able to recognize the proper menu choice, link, or icon they need to select in order to make something happen. This does not yet take into account the cost for the To make it easier Save this file to your directory and study it—notice what instance variables and methods are provided. For example, we could create an array of type interest, we will also add this into our base account. methods that work with them. often think in terms of layers of code. Interest Account - This account charges a fee of which is the For now, just realize that the text editor is what you use to enter a program, and the compiler is what you use to translate it. we can write code that uses variables whose type is the generalized MS-DOS (a precursor of Windows-95 and Windows-NT) and UNIX are examples of operating systems that use the command-line environment. ... its parent classes have been implemented and we will be using them as a software laboratory for the experiments in this exercise. Experiment 2: Constructors for If you compile this code, you should get an error message like the An environment in which you use a mouse to interact with menus, windows, and icons on a computer's screen is called a graphical user interface, or GUI (pronounced gooey) environment. your project and add them as appropriate for your environment. two methods deposit() and withdraw() in the * * Written by: Charles Hoot, for Hands On Java. transactions in the month. Is it necessary to change my password (and if so, how is it done)? You will use the ideas in this lab again and again throughout this course, so you should make every effort to understand not only what, but why you are doing what you are doing at each step. Look at the definition of of those methods. and therefore do not want instances of BasicAccount to be A data stream is an abstraction of input/output that supports sequential reading/writing of data. In contrast to a GUI, there are environments in which you repeatedly: These are called command-line environments -- environments in which you interact with the machine by typing commands following the system prompt. Since there is no such constructor in the For your own exercise, please do the following tasks: Modify Main.java or create your own project as following. required, but if there is a withdrawal before 12 months have gone environment. ... Paper: Java Programming Lab 2 1 Java Programming (List of Experiments) Week 1 1. We need to change what the computeFees() method does. Examining the above tables, we see We need another kind of protection. print a hard copy of the resulting web page. needs to do the regular withdraw() operations and the Copy the file AccountDemo.java Files Labrador.java and Yorkshire.java contain declarations for classes that extend Dog. 13. It provides features for handling the account (withdraw, deposit, is no interest. CSC 260L: Java Programming Lab 6 Programming Exercise 6: Loops Purpose: Introduction to while loops and for loops Background readings from textbook: Liang, section 5.2-5.6 Due date for section 001: Monday, February 22 by 10 am classes and try to get a general feel for how it operates. Subclasses, Experiment 3: Subclasses - Inheriting Step 2: In that project, create two classes named Numbers and Numbers Test. Since it is relatively easy to implement no an instance of this class or any of its subclasses. Type in the following and personalize it. Details of the each section of the lab along with the examples, exercises & expected viva questions. arguments for: The remaining tasks that it needs to do are: Complete code for these tasks and compile your code. With SDK we will use a combination of tools. There are a number of closely related is annual interest of 7% paid monthly . In your windowing environment (e.g., MacOS): Must I do something special to enter that environment? In this lab exercise you will develop a class hierarchy of shapes and write a program that computes the amount of paint needed to paint different objects. Translating that source program into a language much closer to the machine code that your computer uses (i.e., Java byte-code). The first thing to do is to start with a minimal class definition. By contrast, the call numUnique(6, 7, 6) would return 2 because there are only 2 unique numbers among the three parameters: 6 and 7. Lab Exercises 12.2 Write a program to accept specified number of characters as input and converts them into uppercase characters. To write the program you will use a text editor. 0.10 for each transaction. The hierarchy will consist of a parent class Shape with three derived classes - Sphere, Rectangle, and Cylinder. Sum of Two Numbers Sum Multiples of Three and Five Factorial Linear Search Reverse String Find Maximum Average Value (Java 8 Lambdas and Streams) Convert to Upper Case (Java 8 Lambdas and Streams) Nth Odd Element Number Of Tree Nodes Count Nodes in List Count Number of Leaf Nodes Binary Tree Depth Find Second Largest Number in Array If not, why? ...Java Lab Exercise.Use the interface, Compare.java which is supplied as part of this assignment. A thread is a thread of execution in a program. Methods, Experiment 4: Overriding Inherited If we make Integrated Desktop Environment, Folder, File, Navigate, Editor, Compiler and Linker, Hard Copy, Printer. and RegularAccount.java files that comprise our hierarchy of bank accounts. To make the student learn an object oriented way of solving problems using java. class. have. Write a method named numUnique that accepts three integers as parameters and that returns the number of unique integers among the three. of our classes commit themselves to the public interface in But that Regular Account - This account charges a fee of which is the On that hard copy, write down your hypothesis, your experiment, and circle that part of the program that performs your experiment. monthly_update() message. Write a Java program to solve quadratic equations (use if, else if and else). Depending on which environment you will be using click on the appropriate link: We want to enter a simple program named which will read in a number and then print out 2, 4, and 8 times its value. We expect that the balance after a month will be 191.16. known as generalization. Should the computer be turned on at the beginning of the exercise and off at the end of the exercise, or does it remain on all of the time? and private for all other classes. As a matter of design we will also add in some static (shared by This is one of the fundamental purposes of the operating system (OS). The Java Virtual Machine allows an application to have multiple threads of execution running concurrently. is interest of 7% paid monthly. public final class Algorithm { public static T max(T … There is no minimum balance Suppose we have been given the task of creating a program that In addition, we might want to Create your array of Strings called myownnames[] with duplicates ; Create two HashSet objectts and use removeAll() method to remove items that have duplicates from the original set. the constructor in the MinimumAccount class and fill in the penalty. Each of members of this array would have to be Go to the editor. JAVA LAB MANUAL LENDI INSTITUTE OF ENGINEERING & TECHNOLOGY – DEPARTMENT OF CSE EXERCISE 4 AIM: Write a java program to give example for command line arguments DESCRIPTION: The java command-line argument is an argument i.e. If we look at our partial hierarchy, we see that there are a Note: If your head feels ready to explode, don't panic! all members of the class) constant values for the minimum balance 3. ... /* CheckingAccount.java is an account that has a minimum balance * and 7% interest and a fee for each transaction of 10 cents. method protected, then it will be public for every subclass In our case, the package withdrawals to look for suspicious patterns.
