String conversion

[Mini Pilla]

Hi All,
Can someone give me an idea to get around this small problem??
I don't want to lose "0" when I convert a string conatining "0" at the begining to lose.
For Ex:
When I convert "06789" to an int,we know that we get 6789.
Can I get 06789.
Thanx

Why are you trying to parse it into an int? If you need the leading zero(s), can't you keep it as a string? Can you explain a little more about how you are using the value?

OK!!!
Let me give more insight.....
I am reading a column from a CSV file which has numbers say "06789".
I am converting all those numbers into Int and storing them into a vector.
This vector I am passing into a TreeSet for sorting,from where I am taking min and max values.
I am outputing those values to users but while doing that I want to output 06789 as 06789 instead of 6789.
HOpe I was sucessful!!!
Thanx

java.text.DecimalFormat

I was thinking of DecimalFormat too. It works when you have a known number of digit. What if you enter "006879"? You have to keep track of the String length...

Then maybe ya just shouldn't be convertin' the input to a number and keep it as a String since that would seem to be what is desired.

And additionally use a custom Comparator for the TreeSet, so that the values get sorted by int value instead of lexicographically.
