Consider the following classes:

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

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

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

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

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

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

public class Jerry extends Kurt {
    public void c() {
        System.out.println("Jerry 3");
        super.c();
    }
}

Suppose the following variables are defined:

Kurt   var1 = new Jerry();
Chris  var2 = new Chris();
Kurt   var3 = new Eddie();
Kurt   var4 = new Chris();
Object var5 = new Jerry();

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();
((Chris) var5).a();
((Jerry) var1).a();
((Jerry) var4).a();
((Chris) var3).b();
((Eddie) var3).b();
((Jerry) var4).c();
((Kurt) var5).c();
