Hi I am working in Java

I have to create min 5 digit integer value that should start with 1

for example 1 should be 00001
2 should be 00002 etc

00001
00002
...
...
99999
100000
100001
100002
...
...

and if we have a list of above values, I also need to find the earliest no from the list

Please help me with this logic

Many Thanks

you can't hold integer prepadded with 0s but can be manipulated using string when you want to display or print,

for e.g.,

int i = 1 ;
System.out.println( String.format( "%05d", i ) );

would print 00001

for finding the smallest from a list, use comparator and then use Collections.sort to sort. then you can take the smallest/largest from the list!

You can create the numbers stirngs(not integers) by prepending the required number of 'Zeros'.
