Re: 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()

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

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:

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

Hi&nbsp;
&nbsp;
I'm not a groovy scripter - i'd like to be, but what i need is a absolutely no initial coding skills groovy course, which doesnt exist - so I tend to just steal snippets of what other people have given me and try and expand those with help - but isn't what you want just a simple concatenation?
&nbsp;
Just considering how datatypes work - you wouldn't be able to maintain any leading zeros on an integer I wouldn't have thought cos the zero's would get dropped as 0000012345 = 12345 if numeric - so the values would have to be treated as a string.
&nbsp;
my ridiculously poor coding skills have come up with the following:
&nbsp;
a = "12345";
b = "00000";

log.info(b+a);
When I executed the above - the response was as follows:&nbsp;&nbsp;
&nbsp;
Sun Sep 23 12:12:21 BST 2018: INFO: 0000012345
&nbsp;
Is this what you wanted? or have I missed something essential again?
&nbsp;
Cheers,

if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
