我正在尝试让我的代码创建创建手机对象所需的新构造函数对象。我尝试命名构造函数字段来创建对象。
更新：我已经修改string为String，但是现在当我更新它时，我得到了错误：
error: constructor Mobile(java.lang.String,int,int,java.lang.String,int,java.lang.String) is already defined in class Mobile
此错误出现在页面底部：
public Mobile(String MobilephoneType, int Mobilescreensize, int Mobilememorycardcapacity, String newserviceprovider, int Mobilecameraresolution,
String MobileGPS) {
这个错误是什么意思？
到目前为止的代码：
/**

public class Mobile
