CupPillJarBox

Author: Robert Baxter

Consider the following classes:

public class Cup extends Box {
    public void method1() {
        System.out.println("Cup 1");
    }

    public void method2() {
        System.out.println("Cup 2");
        super.method2();
    }
}

public class Pill {
    public void method2() {
        System.out.println("Pill 2");
    }
}

public class Jar extends Box {
    public void method1() {
        System.out.println("Jar 1");
    }

    public void method2() {
        System.out.println("Jar 2");
    }
}

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

    public void method3() {
        method2();
        System.out.println("Box 3");
    }
}

Suppose the following variables are defined:

Box var1 = new Box();
Pill var2 = new Jar();
Box var3 = new Cup();
Box var4 = new Jar();
Object var5 = new Box();
Pill var6 = new Pill();

Indicate on each line below the output produced by each statement shown. 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, write the word error to indicate this.

var1.method2();
var2.method2();
var3.method2();
var4.method2();
var5.method2();
var6.method2();
var1.method3();
var2.method3();
var3.method3();
var4.method3();
((Cup) var1).method1();
((Jar) var2).method1();
((Cup) var3).method1();
((Cup) var4).method1();
((Jar) var4).method2();
((Box) var5).method2();
((Pill) var5).method3();
((Jar) var2).method3();
((Cup) var3).method3();
((Cup) var5).method3();
