Question

您好我正在使用Java执行命令系统。例如：您输入＆＃34; date＆＃34;然后你会看到时间和日期但是这个问题出现了，当我试图修复它时，它是一个永无止境的循环。这里的代码有一点解释：

switch(string){
case "date":
    //Give date

case "random":
    //The thing is when you type "random" it will wait on the next input from the user and store it in this variable.

    while(!string2.equals("BREAK")){
        String string2 = (String) inputdata.readObject();
        //It will process the users next information if the user NOT type "BREAK".
    }
    break;

    //The problem is that the variable "string2" must be outside the while loop BUT it NEEDS in the loop. I tried with do while loop but the same problem happend.
}

如果我必须解决这个问题，我必须在循环中的循环循环中循环.... 谢谢你的回答。：D评论，如果你不明白，我在开头就不明白我的问题。

你可以在循环之外声明string2然后在里面引用它吗？

String string2;
switch(string){
case "date":
//Give date

case "random":
//The thing is when you type "random" it will wait on the next input from the user and store it     in this variable.

while(!string2.equals("BREAK")){
    string2 = (String) inputdata.readObject();
    //It will process the users next information if the user NOT type "BREAK".
}
break;

//The problem is that the variable "string2" must be outside the while loop BUT it NEEDS in the loop. I tried with do while loop but the same problem happend.
}

Java Socket永无止境循环
