Assuming that the following classes have been defined: 

        public class Horse extends Cat {
            public void method1() {
            System.out.println("Horse 1");
        super.method2();
            }

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

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

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

        public class Cat extends Dog {
            public void method3() {
            System.out.println("Cat 3");
        method2();
            }
        }

And assuming the following variables have been defined: 

    Cat var1 = new Pig();
    Dog var2 = new Dog();
    Dog var3 = new Cat();
    Object var4 = new Horse();
    Cat var5 = new Horse();
    Horse var6 = new Pig();

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.method3();
var2.method3();
var3.method3();
var4.method3();
var5.method3();
var6.method3();
((Pig)var5).method1();
((Cat)var3).method3();
((Cat)var4).method1();
((Pig)var1).method1();
((Horse)var4).method1();
((Cat)var2).method3();
((Horse)var3).method1();
((Dog)var4).method2();
