How do I ping a host? - Learn Java by Examples

Since Java 1.5 (Tiger) the java.net.InetAddress class introduces isReachable() method that can be used to ping or check if the address specified by the InetAddress is reachable.

package org.kodejava.net;

import java.net.InetAddress;

public class PingExample {
    public static void main(String[] args) {
        try {
            InetAddress address = InetAddress.getByName("172.16.2.0");

            // Try to reach the specified address within the timeout
            // period. If during this period the address cannot be
            // reach then the method returns false.
            boolean reachable = address.isReachable(10000);

            System.out.println("Is host reachable? " + reachable);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
