Question

我一直在努力解决以下4个错误。

这是一个简短的可重复的例子：

import java.util.logging.Level1;
import java.io.OutputStream;
import java.io.InputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.SocketAddress;
import java.util.logging.Logger;

public class RcvThread2 implements Runnable{
    private static final int sizeBuf = 50;
    private Socket clientSock;
    private Logger logger;
    private socketAddress clientAddress;

    public RcvThread2(Socket clntSock, socketAddress clientAddress, Logger logger) {
        this.clientSock = clntSock;
        this.logger = logger;
        this.clientAddress = clientAddress;
    }

    public void run(
        try {
            InputStream ins = clientSocket.getInputStream();
            OutputStream outs = clientSocket.getOutputStream();
            // ...

为什么我会收到这四个编译错误？我该如何修理它们？

error : cannot find symbol
import java.util.logging.Level1;

symbol: class Level1
location: package java.util.logging

error : cannot find symbol
InputStream ins = clientSocket.getInputStream();

symbol: variable clientSocket
location: class RcvThread2

error: cannot find symbol
OutputStream outs = clientSocket.getOutputStream();

symbol : variable clientSocket
location: class RcvThread2

删除行import java.util.logging.Level1;（不存在，我认为您需要import java.util.logging.Level）。并且socketAddress clientAddress应为SocketAddress clientAddress（这就是您使用clientAddress获取有关未定义方法的消息的原因。）

为什么Java编译器找不到符号？
