Assume that the following classes have been defined: 

public class Leela extends Fry {
    public void method1() {
        System.out.print("Leela1 ");
    }
    
    public void method2() {
        System.out.print("Leela2 ");
        super.method2();
    }
}

public class Farnsworth extends Bender {
    public void method1() {
        System.out.print("Farnsworth1 ");
    }
    
    public String toString() {
        return "Good news everyone!";
    }
}

public class Fry extends Bender {
    public void method2() {
        System.out.print("Fry2 ");
        super.method2();
    }
}

public class Bender {
    public void method1() {
        System.out.print("Bender1 ");
    }
    
    public void method2() {
        System.out.print("Bender2 ");
        method1();  
    }
    
    public String toString() {
        return "We're doomed!";
    }
}

Given the classes above, what output is produced by the following code? 

Bender[] rodriguez = { new Leela(), new Bender(), new Farnsworth(), new Fry() };
for (int i = 0; i < rodriguez.length; i++) {
    rodriguez[i].method2();
    System.out.println();
    System.out.println(rodriguez[i]);
    rodriguez[i].method1();
    System.out.println();
    System.out.println();
}
elements[0]: Leela
elements[1]: Bender
elements[2]: Farnsworth
elements[3]: Fry
