用Telphone iphone = new Iphone();和Iphone iphone = new Iphone();具体区别？

public class Text {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

Telphone iphone = new Iphone();

iphone.call();

iphone.messge();

Callphone callphone = new Callphone();

callphone.call();

callphone.messge();

}

}
