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. |
Class – Example
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;
}
}
Object – Example
Following is the example for creating an object for Employee class
Employee e = new Employee();
