如何实现ping效果呢？

实现思路:
    使用isReachable()方法即可实现ping效果

package com.java265.other;
import java.net.InetAddress;
public class Test {
	/*
	 * java265.com java模拟ping效果的示例分享
	 */
	public static void main(String[] args) throws Exception {
		String ipAddress = "23.254.230.95";
		InetAddress inet = InetAddress.getByName(ipAddress);

		System.out.println("ping: " + ipAddress);
		System.out.println(inet.isReachable(5000) ? "可ping通" : "主机不存在!");
	}
}
