For that you need a way to pad the output, cattleDrive provide a method there, change " " to "0".

[B]import myUtils.myUtils.*;[/B]

it should be import myUtils.myUtils;

use the ? : operator.

Rob,

As Tim mentioned if you want to use Integer.parseInt(), you
have to handle the exception otherwise the program may terminated
ugly with some annoying exception message when user enter non-parsable string.

If you want to use parseInt() to implement isInteger(), you'll have to catch the exception.

first thing come to my mind is :

looping through the String s, for each
character ues Character.isDigit() to check.

Also pay attention to the possible positive/negative sign
at the beginning of the String s, as +/- are not digits
but could be part of valid integer.

...
user just inputs something and it gets printed out again
...

Things got complicated because you are not just got
anything from user then output it.

With System.out.print("Enter a number: ");
You are asking user to enter a number, then Integer.parseInt(input)
convert the input from String to integer.

Problem is user may not always follow the instruction and might enter something that is NOT parsable to integer.

To check this, the code was wrapped into try-catch block for possible Exception.

Hi,

I am palying with JFileChooser, I put out some code and it does shows
a openDialog box when run.

Problem is the program does NOT terminate after I choose a file & click OK.
(I did not see the promt appear)

Please advise if I did something wrong ?

import javax.swing.JFileChooser; import javax.swing.filechooser.FileFilter; import java.io.File; class FDialog { public static void main (String[] args) { JFileChooser chooser = new JFileChooser(new File(".")); chooser.setSelectedFile(new File("Play.java")); chooser.setFileFilter(new FileFilter() { // anonymous class for FileFilter public boolean accept(File f) { return f.getName().toLowerCase().endsWith(".java") || f.isDirectory() ; } public String getDescription() { return "*.java"; } }); int result = chooser.showOpenDialog(null); System.out.println(result); System.out.println(chooser.getSelectedFile().getName()); } }

First follow Ernest's advice by adding

import java.io.*;

you should see some difference.

1. usel Calendar.getInstance() to get a Calendar object.
2. call set(year, month, data) to set the date you need
3. call get(Calendar.DAY_OF_WEEK) to get the day, it return a number between
1 - 7 (Sunday - Saturday).

HTH

You need Collections.shuffle(Arrays.asList(cards);
