System.out.println(line);
   }

output on console i m getting in proper format

     bash.exe              3360 Console             2      7,840 K

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 ,

    Image Name                     PID Session Name        Session#    Mem Usage
    ========================= ======== ================ =========== ============
    System Idle Process      0 Services                     0  4 K
    System                      4 Services                0 10,024 K

    csrss.exe                      436 Services            02,252 K

----------------------------------UPDATE-------------------------------

Formatting issue resolved by changing the font of Textarea , now its properly aligned

Answer 1

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.

Answer 2

You may want to use a JTable, using a JTable everything is in rows and columns like a spreadsheet. It may require more code than you already have but rest assured it will work (if programmed correctly)

To start off with you will need a 2-dimensional array like this:

private String[][] data = {
        {"Example 1", "0.0.1", "Update"},
        {"Example 2", "0.0.1", "Installed"}
};

Once you have this you will need a array of columns like this:

private String[] columns = {"Mod name", "Version", "Installed"};

Once you have both of these you can use this to make the table:

JTable table = new JTable(data, columns);
