Kill a Windows process with Java

I would like to kill a process in Java for an application in Java 1.4. ; I don't want to (can't) add some custom libraries so I will use 'Runtime' class to execute a DOS command:

tasklist: allow me to recover all processes running.

taskkill: allow me to destroy a process by its ID.

This is a Java class which will use these both commands to do the job:

KillProcess.java

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; public class KillProcess {       public static final int FIRST_COLUMN_LENGTH = 26;              /**       * pass all statements which must be found in the process description       *     process definition columns are:       *            - Image Name       *            - PID       *            - Session Name       *            - Session#       *            - Mem Usage       *            - Status       *            - User Name       *            - CPU Time       *            - Window Title       * @param args {String[]}: statements which must be found in the process description       * @throws IOException       */       public static void kill(String[] args) throws IOException{             int processId = 0;             // recover a file output from the DOS command 'tasklist'             // which list all running processes             Process process = Runtime.getRuntime().exec("tasklist /v");             InputStream inputstream = process.getInputStream();             InputStreamReader inputstreamreader = new InputStreamReader(inputstream);             BufferedReader bufferedreader = new BufferedReader(inputstreamreader);             String line;             while ((line = bufferedreader.readLine()) != null) {                   boolean blnFound = true;                   // loop on all statements to verify if the line contains it                   for (int i=0;ilength;i++){                         if (line.indexOf(args[i])<0){                               blnFound = false;                         }                   }                   if (blnFound){                         line = line.substring(FIRST_COLUMN_LENGTH);                         while(line.charAt(0)==' '){                               line=line.substring(1);                         }                         String strProcessId = line.substring(0, line.indexOf(' '));                         processId = Integer.parseInt(strProcessId);                   }             }             // verify the process has been found             if (processId!=0){                   // kill the process via 'taskkill'                   Runtime.getRuntime().exec("taskkill /pid " + processId + " /f");                   System.out.println("The process "+processId+" has been killed!");             } else{                   System.out.println("Process not found!");             }       }       public static void main(String[] args) throws IOException{             kill(args);       } }

This is an example of class use which will kill my IrfanView process ...

java KillProcess i_view32.exe IrfanView
