Hi all,
I need to format a number into a String. The pattern should be of 4 digit. How can I achieve that? For example if value of an int is 1, I should get 0001 after formatting and if there is 123, I should get 0123.

Try this out:
http://www.particle.kth.se/~lindsey/JavaCourse/Book/Code/Tech/Formats/CJ/com/horstmann/format/Format.java
Just change the printf-Methods, that they return the wanted value.
With this changed class you can write something like:
Format.printf( "%4d", YourLongValue );
Hope this helps

(This should probably be in our FAQ.)
Take a look at the java.text.DecimalFormat.
Were you able to figure it out? If you'd like another nudge in the right direction, just ask. Do feel free to post any relevant code you're working on.
