Question

package Test;

public class A {

    public A() {
        System.out.println("Enter construct A...");
        init();
    }

    public void init() {
        System.out.println("Enter A's init...");
    }

}

package Test;

public class B extends A {

    int i = 0; 
    int j;

    public void init() {
        System.out.println("Enter B's init...");
        i = 100;
        j = 100;
    }

    public void printAll(){
        System.out.println(i);
        System.out.println(j);
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        B b = new B();
        b.printAll();
    }

}

Answer 1

Okay, new B gets first an A get created, first instance fields, then calling B’s init() which sets i and j to 100. Then the B gets created, which initializes the i to 0.

Enter construct A...
Enter B's init...
0
100
