Hello Friend,

A class is a blue print through which an object is created. In Java, all things are based on class and object.

class Person {

       String name = "";
       int age = 0;

       void changeName(String name1) {
            name = name1;

       void changeAge(int age1) {
            age = age1;
            void print() {
class PersonInformation{
    public static void main(String[]args){
    Person p=new Person();

The design of this class is based on the person objects. The fields name and age represent the state of object, and the methods- changeName and changeAge define its interaction with the outside world.The Person class does not contain a main method as it is just the blueprint for persons that might be used in a program.The class PersonInformation takes the responsibility of creating and using person objects.
