A class in java is a user-defined type that describes what a certain type of object will look like. A class description consists of a declaration and a definition. Usually these pieces are split into separate files. An object is a single instance of a class. You can create many objects from the same class type.

class Employee{
    int id;
    String  name;

    public void setId(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public void setName(String  name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

public class tut9 {
    public static void main(String[] args) {
        Employee e1 = new Employee();
        e1.setId(1);
        e1.setName("Employee 1");
        System.out.println(e1.getId());
        System.out.println(e1.name);
    }
}
