在Java编程中,如何获取本地计算机的IP地址和主机名?
以下示例显示如何使用InetAddress
类的getLocalAddress()
方法获取系统的本地IP地址和主机名。
package com.yiibai;
import java.net.InetAddress;
public class GetLocalIPAddress {
public static void main(String[] args) throws Exception {
InetAddress addr = InetAddress.getLocalHost();
System.out.println("Local HostAddress: " + addr.getHostAddress());
String hostname = addr.getHostName();
System.out.println("Local host name: " + hostname);
}
}
上述代码示例将产生以下结果 -
Local HostAddress: 192.168.1.50
Local host name: YB-PC
