Java 实现判断 主机是否能 ping 通

Java 实现判断 主机是否能 ping 通

---

代码实现如下：

import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;

/**

public class PingUtil {
    public static void main(String[] args) {
        String host1 = "14.215.178.37";
        String host2 = "www.baidu.com";
        ping(host1);
        ping(host2);
    }

    /**
     * 判断主机地址能不能 ping 通，此处主机地址可以域名或者IP
     * @param host
     * @return
     */
    public static void ping(String host) {
        try {
            InetAddress inetAddress = InetAddress.getByName(host);
            boolean reachable = inetAddress.isReachable(5*1000);
            if(reachable) {
                System.out.println("ping success. Host name: " + inetAddress.getHostName() + ", IP addr: " + inetAddress.getHostAddress());
            }else {
                System.out.println("ping failed.");
            }
        } catch (UnknownHostException e1) {
            e1.printStackTrace();
        } catch (IOException e2) {
            e2.printStackTrace();
        }
    }
}

运行结果如下：

ping success. Host name: 14.215.178.37, IP addr: 14.215.178.37
ping success. Host name: www.baidu.com, IP addr: 14.215.177.39
