Cone

Assuming that the following classes have been defined: 

        public class Scoop extends Spoon {
            public void method1() {
                System.out.println("Scoop 1");
            }
        
            public void method3() {
                System.out.println("Scoop 3");
            }
        }

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

            public void method2() {
                System.out.println("Cone 2");
                method1();
            }
        }

        public class Spoon extends Cone {
            public void method1() {
                System.out.println("Spoon 1");
                super.method1();
            }
        }

        public class Cup extends Cone {
            public void method3() {
                System.out.println("Cup 3");
            }
        }

And assuming the following variables have been defined: 

        Cone var1 = new Scoop();
        Cone var2 = new Spoon();
        Cone var3 = new Cone();
        Object var4 = new Spoon();
        Spoon var5 = new Scoop();
        Object var6 = new Cup();

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();
var4.method2();
var5.method2();
var6.method2();
((Spoon)var1).method3();
((Cup)var6).method3();
((Scoop)var4).method1();
((Cone)var6).method2();
((Cone)var4).method1();
((Scoop)var6).method3();
((Scoop)var3).method3();
((Scoop)var5).method3();
