Re: How clear console using java

Hi,

I am using Jdk1.5 for development. I need to clear java console after
printing 100 lines of test on console. I tried below code it is
working for compiling java (.java) but it through exception
(IOException).

        try {
            Process dir = Runtime.getRuntime().exec("cls");
            BufferedReader bufr_in = new BufferedReader(new
InputStreamReader(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 system
cannot 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 more

Please guide me, where I am going wrong thing? And how I can clear
console through my code?
