You design a class named Computer. This class needs to have following member variables and member methods:

Member Variables	private String data field named brand
	private boolean data field name status that specifies if the computer is on or not (default is false)
	private double data field name weight (default is 5.5)
	private int data field named ram (default is 0)
Constructors	Default constructor: public Computer()
	public Computer(int r, String b)
	public Computer(int r, String s, double w) (r is ram, s is the brand and w is the weight)
Methods	The accessor and mutator methods for all four data fields
	A method named toString() that returns string description of the computer.

You need to implement a TestComputer class. In this Test class, you need to create three Computer objects (C1, C2, and C3) using different constructors. Change the value of C1 (created by default) with users input values of brand HP, 4 pounds, and 16G ram. Get users input for ram and brand to create C2 using second constructor. After that, get users input of weight for C2, and change C2s weight. Get users input for ram, brand and weight to create C3 using third constructor.

Display objects by invoking their toString method.
