Forward Refrence

[rohan yadav]

public class ForwardRef
{
    int j = getI();
    int i = 5;
    
    private int getI() { return i; }
    
    public static void main(String[] args)
    {
        System.out.println(new ForwardRef().j);
    }
}
    

Why the output of above program is 0

[Ankur kothari]

because when you call the getI() the i is initialised to its default value...

[rohan yadav]

But i thought that wen getI() method return i it would have been initialized to 5, because int i = 5; statement would be executed first.
Am i right??

[Ankur kothari]

hey when int j is being executed the line int i=5 isnt executed....that is why the jvm only knows about the variable i...so default value

[rohan yadav]

ohhhhhh got it

Concept: The initalization of the variable happen in the order in which the variable appear.
In this case when j is initialized the value of i is initialized to 0.
