Blue

Assuming that the following classes have been defined: 

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

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

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

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

        public class Blue {
            public void method1() {
            System.out.println("Blue 1");
        method2();
            }

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

        public class Red extends Blue {
            public void method2() {
            System.out.println("Red 2");
        super.method2();
            }
        }

And assuming the following variables have been defined: 

    Blue var1 = new Blue();
    Green var2 = new Green();
    Object var3 = new White();
    Red var4 = new Green();
    Blue var5 = new Red();
    Blue var6 = new White();

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();
var1.method2();
var2.method2();
var3.method2();
var4.method2();
var1.method3();
var2.method3();
var3.method3();
var4.method3();
((Blue)var3).method1();
((Red)var3).method2();
((White)var3).method3();
((White)var4).method3();
((Green)var5).method3();
((Red)var5).method1();
((Blue)var6).method3();
((Green)var6).method3();
