Q1: Write a Java class called Machine which has:
 2 instance variables brandName and power (to check if it is On or not)
 2 constructors (a multi-argument constructor and a zero-argument one)
 getters for the two instance variables
 a setter for brandName
 2 methods switchOn() and switchOff() which change the value of power
 a method called display() to print the status of the machine
Q2: Write a Java class called TestMachines which has a main method to test your
code as follows:
 create a Machine object to be initialized to "Dell" brand and to be Off.
 create another Machine object using the zero-arg constructor. Then change its
brand to "Sharp" and switch it on.
 print the status of the 2 machines.
 declare and create an array that can hold up to 3 machines
 fill the array with suitable data
 print how many machines of brand "Dell"
 declare and create an ArrayList of machines
 fill the list with suitable data
 print how many machines are On.
