    If methods with the same name are defined in both superclass and subclass, the method in the subclass overrides the method in the superclass. This is called method overriding. Example 1: Method overriding Output In this example, by making an object dog1 of Dog class, we can call its method printMessage() which then executes the display() statement. Since display() is defined in both the classes, the…

    Java program to create an enum class Output In the above example, we have created an enum class named Size. The class contains four constants SMALL, MEDIUM, LARGE, and EXTRALARGE. Here, the compiler automatically converts all the constants of the enum into its instances. Hence, we can call the method using the constant as objects. In this call, the this keyword is…

    Java program to print the object Output In the above example, we have created an object of the class Test. When we print the object, we can see that the output looks different. This is because while printing the object, the toString() method of the object class is called. It formats the object in the default format. That…

     Java program to create a private constructor Output In the above example, we have created a private constructor of the Test class. Hence, we cannot create an object of the Test class outside of the class. This is why we have created a public static method named instanceMethod() inside the class that is used to create an object of the Test class. And from the Main class,…

    In this tutorial we will see how to calculate area and circumference of circle in Java. There are two ways to do this: 1) With user interaction: Program will prompt user to enter the radius of the circle2) Without user interaction: The radius value would be specified in the program itself. Program 1: Output: Program 2:…
