Chair

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

Assuming that the following classes have been defined: 

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

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

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

            public void method3() {
            System.out.println("Table 3");
        method1();
            }
        }

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

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

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

And assuming the following variables have been defined: 

        Table var1 = new Table();
        Chair var2 = new Table();
        Table var3 = new Couch();
        Chair var4 = new Lamp();
        Chair var5 = new Couch();
        Object var6 = new Chair();

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.method2();
var2.method2();
var3.method2();
var4.method2();
var5.method2();
var6.method2();
var1.method1();
var2.method1();
var3.method1();
var4.method1();
var1.method3();
var2.method3();
var3.method3();
((Lamp)var4).method1();
((Lamp)var2).method1();
((Table)var5).method1();
((Couch)var1).method1();
((Chair)var6).method2();
((Couch)var5).method3();
((Table)var5).method3();
