Peak

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

Assuming that the following classes have been defined: 

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

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

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

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

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

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

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

And assuming the following variables have been defined: 

        Peak var1 = new Cliff();
        Gorge var2 = new Gorge();
        Peak var3 = new Hill();
        Peak var4 = new Gorge();
        Peak var5 = new Peak();
        Object var6 = new Cliff();

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();
((Gorge)var6).method1();
((Cliff)var3).method2();
((Gorge)var4).method2();
((Gorge)var3).method2();
((Hill)var3).method2();
((Gorge)var1).method1();
((Cliff)var4).method3();
((Peak)var6).method3();
