使用Java的Runtime 就可以了，代码如下：
/*

*
* TODO To change the template for this generated file go to
* Window - Preferences - Java - Code Style - Code Templates
*/
package org.mytech.test;

import java.io.*;

/**

*/

public class RunPing {

public static void main(String[] argv) {
try {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("ping www.163.com");
BufferedReader reader = new BufferedReader(new InputStreamReader(
process.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

String IPAddre="127.0.0.1";
Process process = Runtime.getRuntime().exec("ping"+IPAddre); 
BufferedReader message= new BufferedReader(new InputStreamReader(process.getInputStream());
while(message.readLine()!=null){
   System.out.println(message);
}
