Question

我有一个客户端类，其中值“number”应该总是相应地改变为用户输入但是在每个循环之后它保持与第一个条目相同，例如：用户输入F下一个循环它将打印F而不是任何东西但。我尝试使用私有方法创建它的新实例，但我不断得到枚举错误，我不知道如何处理。

public class Client {

public static void main(String args[]) throws UnknownHostException, IOException {
    boolean test = true;
    Socket s = new Socket("127.0.0.1", 6115);
    Scanner sc = new Scanner(System.in);
    Scanner sc1 = new Scanner(s.getInputStream());
    PrintStream p = new PrintStream(s.getOutputStream(), true);
    //String number;
    while (test) {
        String number;
        number = "";
        System.out.println("Enter any string");
        number = sc.nextLine();
        p.println(number);

        //flushing printstream not variable?
        number = sc1.nextLine();
        System.out.println("CALLED");
        System.out.println(number);
        p.flush();
        System.out.println("Would you like to enter another string? Y/N: ");
        String cont1 = sc.nextLine();
        if (cont1.equals("N")) {
            test = false;
            System.out.println("Goodbye! ");
        }
    }
    s.close();
    sc.close();
    sc1.close();
}
}
private void resetVariable() {
    Client = new Client();

}

错误是“错误：（43,17）java：class，interface或enum expected”将光标放在私有对象的void之后

然后“错误：（46,9）java：class，interface或enum expect”突出显示私有对象中的括号

将您的方法移到类中： -

    } // This closes main
    //} // This was closing the Class Client
    private void resetVariable() {
        Client = new Client();

    } // This closes resetVariable
  } // This should now close Class Client

更新：通过以下评论 - 您还应该考虑从成员函数Client中实例化类resetVariable

循环中重置变量
