Hi,I am using Jdk1.5 for development. I need to clear java console afterprinting 100 lines of test on console. I tried below code it isworking for compiling java (.java) but it through exception(IOException).        try {            Process dir = Runtime.getRuntime().exec("cls");            BufferedReader bufr_in = new BufferedReader(newInputStreamReader(dir.getInputStream()));            String readLine = "";            if( ( readLine = bufr_in.readLine() ) != null )            {              System.out.println(readLine);              while( ( readLine = bufr_in.readLine() ) != null )                  System.out.println (readLine);            }        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }Above code throws exception at run time.java.io.IOException: Cannot run program "cls": CreateProcess error=2,The system cannot find the file specified    at java.lang.ProcessBuilder.start(Unknown Source)    at java.lang.Runtime.exec(Unknown Source)    at java.lang.Runtime.exec(Unknown Source)    at java.lang.Runtime.exec(Unknown Source)    at atm.Driver.main(Driver.java :52)Caused by: java.io.IOException: CreateProcess error=2, The systemcannot find the file specified    at java.lang.ProcessImpl.create(Native Method)    at java.lang.ProcessImpl.<init>(Unknown Source)    at java.lang.ProcessImpl.start(Unknown Source)    ... 5 morePlease guide me, where I am going wrong thing?
