Exercises Java. Your name.Welcome to our course on Object Oriented Programming in Java using data visualization. People come to this course with many different goals -- and we are really excited to work with all of you! This is an intermediate Java course. We recommend this course to learners who have previous experience in software development or a background in computer science. In achieving this goal you will also learn the fundamentals of Object Oriented Programming, how to leverage the power of existing libraries, how to build graphical user interfaces, and how to use some core algorithms for searching and sorting data.
We are excited to be offering a unique course structure, designed to support learners of different backgrounds in succeeding at their own pace. The first module explains how this will work and if this course is right for you. We also recommend taking a few minutes to explore the course site. A good place to start is the navigation bar on the left.

Welcome to the first week of our course. In this week, we'll get started by introducing ourselves and the Google engineers who will be making appearances throughout the course. We'll also give you of the unique video series we provide and help you understand how to navigate the course to get the most out of it given your background and learning speed.
Finally, we'll jump right into objects and designing classes. This might be a bit of review for some of you who might have learned this in your first programming course. If that's the case, feel free to jump ahead to the Practice Quiz at the end of the week. Let's get started!
In this second part of this week, we'll walk you through setting up your system and working through your first assignment so you'll be having fun with it in no time. Before that though, we'll finish going over some of the fundamentals fundamentals of object oriented programming. Specifically, being able to trace code is a key skill in becoming a stronger programmer. Like the end of last week, the first part of this week might be a bit of a review of material you already learned in your first Java programming course.
In this first real part of the project, you will create an interactive graphical map that will display geospatial data. We encourage you to play around as you watch the videos.A class called circle is designed as shown in the following class diagram.
It contains:. This Circle class does not have a main method. Hence, it cannot be run directly. Let us write a test program called TestCircle in another source file called TestCircle. A class called Author as shown in the class diagram is designed to model a book's author. Write the Author class. Also write a test driver called TestAuthor to test all the public methods, e. A class called Book is designed as shown in the class diagram to model a book written by one author. Write the Book class which uses the Author class written earlier.
Also write a test driver called TestBook to test all the public methods in the class Book. Take Note that you have to construct an instance of Author before you can construct an instance of Book. Take note that both Book and Author classes have a variable called name.
Object Oriented Programming – Java OOPs Concepts With Examples
However, it can be differentiated via the referencing instance. For a Book instance says aBookaBook. There is no need and not recommended to call the variables bookName and authorName. In the earlier exercisea book is written by one and only one author. In reality, a book can be written by one or more author. Modify the Book class to support one or more authors by changing the instance variable authors to an Author array. A class called MyPointwhich models a 2D point with x and y coordinates, is designed as shown in the class diagram.
Notes : Point is such a common entity that JDK certainly provided for in all flavors. A class called MyCirclewhich models a circle with a center x,y and a radiusis designed as shown in the class diagram. The MyCircle class uses an instance of MyPoint class created in the previous exercise as its center. Write the MyCircle class.How i spent my winter vacation for class 6
Also write a test driver called TestMyCircle to test all the public methods defined in the class. A class called MyTrianglewhich models a triangle with 3 vertices, is designed as shown.
The MyTriangle class uses three MyPoint instances created in the earlier exercise as its three vertices. Write the MyTriangle class. Also write a test driver called TestMyTriangle to test all the public methods defined in the class.Object Oriented programming is a programming style which is associated with the concepts like class, object, Inheritance, Encapsulation, Abstraction, Polymorphism.
As Java being the most sought-after skill, we will talk about object-oriented programming concepts in Java. In OOP, computer programs are designed in such a way where everything is an object that interact with one another. Inheritance is one such concept where the properties of one class can be inherited by the other. As we can see in the image, a child inherits the properties from his father. Similarly, in Java, there are two classes:.
Parent class Super or Base class. A class which inherits the properties is known as Child Class whereas a class whose properties are inherited is known as Parent class. In single inheritance, one class inherits the properties of another.
Object Oriented Programming With Java Lab Exercises and Solutions
It enables a derived class to inherit the properties and behavior from a single parent class. This will in turn enable code reusability as well as add new features to the existing code. Here, Class A is your parent class and Class B is your child class which inherits the properties and behavior of the parent class.
When a class is derived from a class which is also derived from another class, i. If we talk about the flowchartclass B inherits the properties and behavior of class A and class C inherits the properties of class B. Here A is the parent class for B and class B is the parent class for C. So in this case class C implicitly inherits the properties and methods of class A along with Class B. When a class has more than one child classes sub classes or in other words, more than one child classes have the same parent class, then such kind of inheritance is known as hierarchical.
If we talk about the flowchart, Class B and C are the child classes which are inheriting from the parent class i. Hybrid inheritance is a combination of multiple inheritance and multilevel inheritance. Since mu ltiple inheritance is not supported in Java as it leads to ambiguity, so this type of inheritance can only be achieved through the use of the interfaces. Now we have learned about inheritance and their different types. Encapsulation is a mechanism where you bind your data and code together as a single unit.
It also means to hide your data in order to make it safe from any modification. What does this mean? The best way to understand encapsulation is to look at the example of a medical capsule, where the drug is always safe inside the capsule.
Similarly, through encapsulation the methods and variables of a class are well hidden and safe. Let us look at the code below to get a better understanding of encapsulation:. Let us try to understand the above code. We have then created a getter and setter methods through which we can get and set the name of an employee. Through these methods, any class which wishes to access the name variable has to do it using these getter and setter methods.
Abstraction refers to the quality of dealing with ideas rather than events. It basically deals with hiding the details and showing the essential things to the user. If you look at the image here, whenever we get a call, we get an option to either pick it up or just reject it. But in reality, there is a lot of code that runs in the background. Therefore, abstraction helps to reduce complexity. You can achieve abstraction in two ways:. Now what does the abstract keyword mean?
If a class is declared abstract, it cannot be instantiated, which means you cannot create an object of an abstract class.All the materials that we are provided for the students is to score Good maximum marks.

Using constructor display the message. Example for call by value. Example for call by reference. And also use the this keyword as return statement. Lab 4 2 Hrs Real Time 4. For this program use the above room. And use these classes in inherit class. Lab 5 2 Hrs Real Time 5. In this class we have three sub classes circle, triangle and square each class has two member function named draw and erase. Create these using polymorphism concepts. It is necessary to make sure that every class from which all other classes in the project will be inherited.
Since any new classes in the project must inherit from the base class, programmers are not free to create a different interface. Therefore, it can be guaranteed that all the classes in the project will respond to the same debugging commands.
