java ping problem

Any one have any idea why this wont work??What its meant to do is put the ping command together and then inserts it into a command window and executes the command.Its putting the ping command together properly but nothing seems to be saving in the textfile "c:\ping.txt".Any help will be greatly appreciated.

public class Ping{

Ping(String Ip,String Ip1){
StringBuffer PingCommand = new StringBuffer("ping -n 1 ");
String PingText = " > c:\\ping.txt";

PingCommand.insert(PingCommand.length(),Ip);
PingCommand.insert(PingCommand.length(),PingText);
System.out.println(PingCommand);
try{

Process PingProcess = Runtime.getRuntime().exec(PingCommand.toString());
}
catch(Exception IO){
}

}
public static void main(String[] args){
Ping p = new Ping("192.168.1.1","");
}
}
