What are return statements in java?

Java

you can understand what is the purpose of return in Java after this simple example

Basically return use in Java to return some values from a method

note: this sample will work on all Java versions, i test it on JDK 1.4

enjoy the code.

file name : Class1.Java

-----

package mypackage1; //package name

public class Class1 //class name + file name the

{

public String add(int a,int b) //a method in the class; its type is String and it take a and b variables; a and b are int

{

int answer = a+b; //this is some code in the class; maybe some operations; no need to know whats happening in this method

System.out.println("I'm in Class1"); //this is some code in the class; maybe some operations; no need to know whats happening in this method

return " I'm the returned value "+ answer; ////this is what you need to take from the method

}

public static void main(String [] arg)

{

Class1 c1 = new Class1(); //creating c1 object from Class1 Class

System.out.println(c1.add(10,6)); //printing the returned values from the method;

}

}

-----------------

output:

I'am in Class1

I'am the returned value 16
