how to add leading zero to a string or integer using groovy script

Hi JayKondra

The Solution Lucian has provided is the quickest and simple but it you want to do an elaborated solution, then you can try below code :

def a = 1234
def stringLen = 10
def strLen = a.toString().size()
expectedLen = stringLen.toInteger() - strLen.toInteger()
for(i = 0; i<=expectedLen-1;i++)
{
	a = "0" + a 
}

log.info a
log.info a.length()

Click "Accept as Solution" if my answer has helped, and remember to give "kudos" :)

Thanks and Regards,

If you have an integer value, the Sting.format method linked by Lucian is ideal, but regarding the other half of your question of padding strings...

Groovy strings have the several padding methods included:

• padRight
• padLeft
• center

So in your example, if the variable "a" was a string, you could do the following:

def a = "12345"
def zeroPaddedString = a.padLeft(10, "0")
log.info(zeroPaddedString)

The following link explains the padding functions in more details:
