Consider the following classes:

public class Polar extends Bear {
    public void b() {
        a();
        System.out.println("Polar 2");
    }

    public void c() {
        System.out.println("Polar 3");
    }
}

public class Bear {
    public void a() {
        System.out.println("Bear 1");
        c();
    }

    public void c() {
        System.out.println("Bear 3");
    }
}

public class Pooh extends Teddy {
    public void b() {
        System.out.println("Pooh 2");
        super.c();
    }

    public void c() {
        System.out.println("Pooh 3");
    }
}

public class Teddy extends Bear {
    public void a() {
        System.out.println("Teddy 3");
        super.a();
    }
}

Suppose the following variables are defined:

Bear   var1 = new Teddy();
Pooh   var2 = new Pooh();
Bear   var3 = new Polar();
Bear   var4 = new Pooh();
Object var5 = new Teddy();

Indicate on each line below the output produced by each statement shown. 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, write the word error to indicate this.

var1.a();
var1.c();
var2.a();
var2.b();
var3.a();
var3.b();
var4.a();
var5.a();
((Pooh) var5).a();
((Teddy) var1).a();
((Teddy) var4).a();
((Pooh) var3).b();
((Polar) var3).b();
((Teddy) var4).c();
((Bear) var5).c();
