Execute batch script from Java

I had a requirement to do a Ping request to a server machine inside java and execute some batch scripts and get results. I found that native ping from java is bit difficult to implement and need some ground level work. Then I found the awesome ProcessBuilder class which can execute OS processes to achieve all my requirements in one implementation. Given below is a simple code for do a windows ping request using this class.

import java.util.ArrayList;
import java.util.List;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.IOException;

public class executeCmd {

public static void main(String[] args) {
try {
List<String> commands = new ArrayList<String>();
//simulate >ping localhost -4
commands.add("ping");
commands.add("localhost");
commands.add("-4");
executeProcess(commands);
}
catch (Exception exc) {
System.out.println("error");
}
}

static void executeProcess(List<String> commands){
ProcessBuilder builder = new ProcessBuilder(commands);
builder.redirectErrorStream(true);
Process p;
try {
p = builder.start();
BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedWriter w = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
String line;
while (true) {
line = r.readLine();
if (line == null) {
break;
}
System.out.println(line);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
