returntypes

[Ramgopal Reddy]

in this aplication whats going exactly i dont know. As per my knowledge front of methods we put returntypes but below aplication Test acts as (?)



class Test {

int a;

Test(int i) {

a = i;

}

Test incrByTen() {

Test temp = new Test(a+10);

return temp;

}

}

class RetOb {

public static void main(String args[]) {

Test ob1 = new Test(2);

Test ob2;

ob2 = ob1.incrByTen();

System.out.println("ob1.a: " + ob1.a);

System.out.println("ob2.a: " + ob2.a);

ob2 = ob2.incrByTen();

System.out.println("ob2.a after second increase: "

+ ob2.a);

}

}

...a constructor, which does not have a return type.

For details on constructors, see this section from Bruce Eckel's Thinking in Java.

        Test(int i) {

a = i;

}    

This is a constructor.

  
 
           Test incrByTen() {

Test temp = new Test(a+10);

return temp;
 
  

This is a method with the [B] Test object [/B} return type. Java is oo language and you can return objects as well as primitives.
