Class vs Object

Following are the difference between Class and Object

Object Class
Object is an instance of a class. Class is a blueprint or template from which objects are created.
Object is a real world entity such as pen, laptop, mobile, bed, keyboard, mouse, chair etc. Class is a group of similar objects.
Object is a physical entity. Class is a logical entity.
Object is created through new keyword mainly e.g. Student s1=new Student(); Class is declared using class keyword e.g. class Student{}
Object is created many times as per requirement. Class is declared once.
Object allocates memory when it is created. Class doesn’t allocated memory when it is created.
There are many ways to create object like new keyword, newInstance() method, clone() method, factory method & deserialization. There is only one way to define class in java using class keyword.

Following is the example for a Employee class

public class Employee {
	private int eid;
	private String ename;
	private int eage;
	public String getEmployeeName() {
		return ename;
