In the following code, no matter what int value i give, it always outputs: 0 is thinking...

Question

class Robot {
int id;
Robot(int i) {
id = i;
Brain b = new Brain();
b.think();
}

private class Brain {
public void think() {
System.out.println(id + " is thinking");
}
}
}

public class Program {
public static void main(String[] args) {
Robot r = new Robot(5);
}
}

Answer 1

Why implementing a Brain class? Just put think() as a public method of Robot.

Answer 2

I just compiled your code and seems to work fine ...

i get "5 is thinking"

Answer 3

jst make public int id; n then try

Answer 4

use this.id=i in constructor u will get the desired output
reply if ur problem is resolved I will explain how it happened
