Maybee something like this will work Runtime.getRuntime().exec("/bin/df -h"); where df = DiskFree

Hello The problem is that method actionPerformed does not have access to your button. You are creating the two buttons inside the LunchPanel constructor. If you create them in the LunchOrder order class it will work just fine. public void actionPerformed(ActionEvent e) {...

Hi I'm not sure what you mean, maybee the following code will fix it ? It will return true or false, depending if the ( and ) are balanced. public class Check { public static boolean BalanceExist(String data) { int left = 0; int right = 0; for(int i = 0 ; i < data.length() ; i++)...

I wrote an exemple but the getLockingKeyState does not work on my machine, FreeBSD5.1. Don't know about other OS.

Sure,there is the JOptionPane and it has a lot of static methods. Eg JOptionPane.showMessageDialog(null,&quot;My Messagebox...&quot;);

Well, there is no method in Java to clear the screen(not what I know about) What you can do is to use the OS commands to do this. If you are running Linux, *BSD or something else look a like you can try this code, it will work fine. public void cleerScreen() throws IOException {...

This one will work import java.awt.*; import javax.swing.*; public class Driver { public static void main(String[]arg) { JFrame frame = new JFrame(); Container cont = frame.getContentPane(); JPanel panel = new JPanel(); JLabel i = new JLabel(new ImageIcon(&quot;mail.gif&quot;))...

Well simdan42. Do you get any errors or something ?

Lets say your file looks like this a|aa|aaa b|bb|bbb c|cc|ccc then the output will be like aaaaaa bbbbbb cccccc or was it something else you wanted ? import java.io.*; import java.util.*; public class Driver { public static void main(String[] arg) throws IOException { StringBuffer...

Opps, sorry there is no add method for the StringBuffer Use append instead.

One way is StringBuffer strBuff = new StringBuffer(); strBuff.add(youStringObject);

Hi. I don't remember the getchar funtion, is it enough to just press one button with getchar or do you need to press one button and then press enter ? well here is one exampel where you must press enter too... import java.io.*; public class Driver { public static void main(String[] arg)...
