2. What is the difference between overloading and overriding a method? 6. Write a constructor for the Undergraduate Student class access the name and age value of 18, and the year value of 0. 9. Suppose the Truck code from the previous problem changes to the following: public class Truck extends Car { public void mi() { System.out.println("Truck 1"); public void m2() { super.m1(); } public String toString() { return super.toString() + super.toString(); ) } Using the same variables form the previous problem, what is the output form the following statements? System.out.println(mytruck); mytruck.m1(); mytruck.m2(); 2. What is the difference between overloading and overriding a method? 6.
