What is a java class

A class is a blueprint of object. In java, class is a keyword, you can not use this keyword to name a variable because it is reserved to represent a class.  In  a class you can create other classes, you can create methods, create global variables and etc. Below is an example of a class Student.

package com.example.myapplication.alert;

/**
 * Created by SONY on 17/10/2016.
 */
public class Student {
    private String name;
    
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

You can use that class by creating the object class first like in the example below :

 Student student = new Student();
        student.setName("Robert");
        String name = student.getName();
