Java中有没有类似于ping的方法

可以用InetAddress的isReachable方法：
import java.net.InetAddress;

public class MainTest {
public static void main(String[] args) {
try {
int timeOut = 3000;
byte[] ip = new byte[] { (byte) 192, (byte) 168, (byte) 100, (byte) 151 };
int retry = 4;
InetAddress address = InetAddress.getByAddress(ip);
for (int i = 0; i < retry; i++) {
if (address.isReachable(timeOut)) {
System.out.println(i + " OK");
} else {
System.out.println(i + " LOSS");
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
