Question

此错误与我之前提出InetAddress.getLocalHost()错误的问题有关。我找到了suggestion在/etc/hosts中添加条目：

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)

Answer 1

您的主机名是Sachin。 exception in thread "main" java.net.UnknownHostException: Sachin: Sachin: unknown error显示。

将Sachin添加到/ etc / hosts

myip     localhost
127.0.0.1   localhost
127.0.1.1   test5
127.0.0.1   Sachin

Answer 2

您可能会在应用程序中联系外部IP地址而您没有连接到互联网。因此，在对主机/ DNS或其他任何内容进行一些更改之前，请检查您的Internet连接......

您还可能需要VPN连接才能访问某些特定网络以访问这些外部URL / IP。所以，检查一下。
