code should be written in java

Exercise 1 [10 Points A microware control panel has four buttons i) increases the time by 30 seconds, ii) switches between power levels 1 and 2 ili areset button iv) start button. Your job is to model the microware control panel in Java and implement a class for simulating the microwave, with appropriate public interface for each button. When client invoke start button, it should print a message "Cooking for-seconds at level replace.. with current state values Write a client program/code to thoroughly test the class. Take snapshots of your tests and include those with submission. Exercise 2 10 Points] Declare a class CobboLock that works like the combination lock in a gym locker, as shown here. The lock is constructed with a combination-three numbers between 0 and 39. The reset method resets the dial so that it points to O. The turnLeft and trunRight methods turn the dial by a given number of ticks to the left or right. The open method attempts to open the lock. The lock opens if the user first turned it right to the first number in the combination, then left to the second, and then right to the third. Write a client program/code to thoroughly test the class. Take snapshots of your tests and include those with submission
