Suppose that the following two classes have been declared:

public class Car $\{$

public void m$1()\{$

System.out.println$("$car $1")$;

$\}$

$$

public void m$2()\{$

System.out.println$("$car $2")$;

$\}$

$$

public String toString$()\{$

return "vroom";

$\}$

$\}$

public class Truck extends Car $\{$

public void m$1()\{$

System.out.println$("$truck $1")$;

$\}$

public void m$2()\{$

super.m$1()$;

$\}$

public String toString$()\{$

return super.toString$()+$ super.toString$()$;

$\}$

$\}$

Write a class MonsterTruck whose methods have the behavior below. Don't just print$/$return the output; whenever possible, use inheritance to reuse behavior from the superclass.

Method Output$/$Return

m$1$

monster $1$

m$2$

truck $1$

car $1$

toString

"monster vroomvroom"
