method overloading in java

/*A class having multiple methods with
same name but different parameters 
is called Method Overloading*/

public class Names{
	static void name(String fname,String lname){
		System.out.println("My firstname is "+fname+" and lastname is "+lname);
	}
	static void name(String fname,String mname,String lname){
		
		System.out.println("My firstname name is "+fname+" and middlename is "+mname+" and lastname is "+lname);
	}
	public static void main(String[] args){
		Names.name("Khubaib","Ahmed");
		Names.name("Khubaib","Imtiaz","Ahmed");
	}
