java线程“main”中的异常java.net.UnknownHostException：测试：测试：未知错误OS ubuntu

问题描述

此错误与我之前的问题有关，我在 InetAddress.getLocalHost（）时遇到错误。我发现在 / etc / hosts ：

This error is related to my previous question where I had an error with InetAddress.getLocalHost(). I found a suggestion to add an entry in /etc/hosts:

myip     localhost
127.0.0.1   localhost
127.0.1.1   test5

但我的错误仍未解决。

我的代码：

import java.net.*;

public class InetAddressTest {
    public static void main(String args[]) throws UnknownHostException {
        InetAddress Address = InetAddress.getLocalHost();

    }
}

错误：

Exception in thread "main" java.net.UnknownHostException: Sachin: Sachin: unknown error
    at java.net.InetAddress.getLocalHost(InetAddress.java:1484)
    at InetAddressTest.main(InetAddressTest.java:6)

推荐答案

您的主机名是Sachin。线程main中的异常java.net.UnknownHostException：Sachin：Sachin：未知错误显示。

Your host name is Sachin. The exception in thread "main" java.net.UnknownHostException: Sachin: Sachin: unknown error show that.

将Sachin添加到/ etc / hosts

Add Sachin to /etc/hosts

myip     localhost
127.0.0.1   localhost
127.0.1.1   test5
127.0.0.1   Sachin
