这篇文章主要介绍了Java判断主机是否能ping通代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
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
