The code is fairly simple , which show currently running processes
Process p = Runtime.getRuntime().exec("TASKLIST");
BufferedReader reader = new BufferedReader(new InputStreamReader(
p.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
output on console i m getting in proper format

to show the output of the code on Jtextarea instead of
System.out.println(line);
i did
textarea.append(line+"\n");
but the formatting shows on text area is not proper as on console ,

----------------------------------UPDATE-------------------------------
Formatting issue resolved by changing the font of Textarea , now its properly aligned
Seems that unlike the console, the font used by textarea is not Monospaced Font.
Either set the JTextArea's font to a monospaced font (or the logical Font.MONOSPACED), or use a JTable to display your data.
