Java中如何获取主机名呢?

Java代码获取主机名的实现思路

使用 
  InetAddress.getLocalHost().getHostName()
方法即可获取主机名

 package com.java265.other;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class TestIKe {
	/**
	 * Java265.com 获取主机名
	 * 
	 * @throws UnknownHostException
	 */
	public static void main(String[] args) throws UnknownHostException {
		String str = InetAddress.getLocalHost().getHostName();

		System.out.println("主机名:" + str);

	}
}
