Puzzle 50 – Solution

Declaring the variable breadth as a static variable solves the problem of forward reference in the puzzle. Static code is referenced and initialized before any instance code – and so the forward reference problem of the breadth variable gets solved.

package com.twister;

public class Area {

    int length = 10;
    int area = length*breadth;
    static int breadth = 20;

    public static void main(String[] args) {
        Area a = new Area();
        System.out.println(a.area);
    }
}
