Hey guys, I found something very useful, so sharing it here.
\nIn one of my project there was a requirement to create a fixed length user-id. Let’s say it was 5 characters ID.
\n
\nSo in other words we required to convert <\/strong>–
\n‘123’ to ‘00123’ and ‘1000’ to ‘01000’ and ‘12345’ will remain ‘12345’.
\nIt appears very simple, but the thing is how quick we do this<\/strong>.
\n
\nEarlier I thought to do this by calculating the length of id and prefixing required number of zeros.
\n
\nAlternate single-line and faster solution is –
\n[groovy]
\n \/\/ following will return a String with size of 5 characters and prefixes zeros (if id has digits lesser than 5).
\n String.format(‘%05d’, id)
\n \/\/ Note down, id is a digit here.
\n[\/groovy]<\/p>\n

That’s all. . isn’t it nice?. We can utilize it at many places like – converting date from ‘1-1-2010′ to ’01-01-2010’.
\nIdea is to introduce such kind of utility. If you already knew this, please ignore \ud83d\ude42
\nplease open the ideas – if you know something better than this.
\n
\ncheers!
