Milk

Author: Stuart Reges (on 2014/02/13)

Assuming that the following classes have been defined: 

        public class Juice extends Fruit {
            public void method2() {
            System.out.println("Juice 2");
        super.method3();
            }

            public void method3() {
            System.out.println("Juice 3");
            }
        }

        public class Egg extends Milk {
            public void method2() {
            System.out.println("Egg 2");
            }

            public void method3() {
            System.out.println("Egg 3");
            }
        }

        public class Milk {
            public void method1() {
            System.out.println("Milk 1");
        method3();
            }

            public void method3() {
            System.out.println("Milk 3");
            }
        }

        public class Fruit extends Milk {
            public void method3() {
            System.out.println("Fruit 3");
        super.method3();
            }
        }

And assuming the following variables have been defined: 

    Milk var1 = new Fruit();
    Juice var2 = new Juice();
    Milk var3 = new Egg();
    Milk var4 = new Juice();
    Milk var5 = new Milk();
    Object var6 = new Fruit();

In the table below, indicate in the right-hand column the output produced by the statement in the left-hand column. If the statement produces more than one line of output, indicate the line breaks with slashes as in "a/b/c" to indicate three lines of output with "a" followed by "b" followed by "c". If the statement causes an error, fill in the right-hand column with either the phrase "compiler error" or "runtime error" to indicate when the error would be detected.

var1.method1();
var2.method1();
var3.method1();
var4.method1();
var5.method1();
var6.method1();
var1.method2();
var2.method2();
var3.method2();
var1.method3();
var2.method3();
var3.method3();
((Juice)var6).method1();
((Fruit)var1).method1();
((Fruit)var3).method2();
((Fruit)var4).method1();
((Juice)var3).method2();
((Egg)var3).method2();
((Fruit)var4).method3();
((Milk)var6).method3();
