Java error - not a statement, what does this mean?
提问by user2898828
I am trying to get my code to create the new constructor objects which I require to create a mobile phone object. I have tried naming the constuctor fields to create the object.
我试图让我的代码创建新的构造函数对象，我需要创建一个移动电话对象。我尝试命名构造函数字段来创建对象。
when I compile my code on this line this.Mobile samsungPhone = new Mobile("Samsung", 1, 2, "verizon", 3 "GPS");I get this error: not a statement, what does this mean??
当我在这一行编译代码时，出现此this.Mobile samsungPhone = new Mobile("Samsung", 1, 2, "verizon", 3 "GPS");错误：不是语句，这是什么意思？
UPDATED CODE!

Mobile Samsung = new Mobile("Samsung", 1, 2, "verizon", 3 "GPS");
There's a comma missing after parameter value 3. I'd say that's your culprit.
参数值 3 后缺少一个逗号。我会说这是你的罪魁祸首。

this.2 = memory card capacity;
this.3=resolution;
Makes no sense at all.
完全没有意义。
You can't assign values to a literal (2, 3).
您不能为文字 (2, 3) 赋值。
Edit: you would also need to fix this:
编辑：您还需要解决此问题：
Mobile Samsung = new Mobile("Samsung", 1, 2, "verizon", 3, "GPS");
As stated by other members.
正如其他成员所说。

Mobile is a class,"this" stand for current object.So,You can't use "this" for Mobile.You should:
Mobile 是一个类，“this”代表当前对象。所以，你不能对 Mobile 使用“this”。你应该：
Mobile samsungPhone = new Mobile("Samsung", 1, 2, "verizon", 3, "GPS");

You need to replace the numbers in your new Mobilector call with reasonable values, as described by what must be comments/notes below, e.g., where you have a 1put in the resolution (which makes no sense unless it's indexed or something), where you have a 2put in the memory card capacity, where there's a 3put in the resolution, etc.
您需要new Mobile用合理的值替换ctor 调用中的数字，如下面的注释/注释所描述的那样，例如，您1在分辨率中放置的位置（除非已编入索引或其他内容，否则没有任何意义），您有一个2放在存储卡容量，那里是一个3决议，等放
Then either comment out the lines that are garbage, or, preferably, delete them.
然后要么注释掉垃圾行，要么最好删除它们。
