Use thisAn object reference that represents the current calling methodSuppose you want to get a reference to the current object within the method, using the keyword this. The Thi

output illustrates this point:Demosuper:Name=kevin age=22The use of this method is more commonly used. In addition, if a member of the parent class can be accessed by a class, you can use it like this, using the "super. Member name in the parent class" way, but often you do not have access to the member names in the parent class.Constructors are a special method in constructors that are called automatically when an object is initialized. In the constructor, this and super also have a variety of

Java's basic arithmetic operators are the same as most other programming languages. These include a plus sign (+), minus (-), Division (/), multiplication (*), and modulus (%, which gets the remainder from integer division). Integer division cuts the decimal number directly, not the rounding. Java also operates in a shorthand form, with assignment operations at the same time. This is marked by an operator before the equal sign, and is fixed for all operators in the language. For example, to add

, you can instantiate the class of the method or member variable directly in the static method. This is what public static void main does.Example 3 public class Staticcls {public static void Main (string[] args) { outercls.innercls oi = new Outercls.innercls (); /This does not need to be new one Outercls } } class Outercls {public static class Innercls { innercls () { System.out.println ("Innercls");}} Results: Innercls 3.
