How do I generate a random number between 2 values

[manpreet.mukkar]

Hello Team,

I have a coding question about how do I generate a random number whose minimum character length is 2 and max is 4. In other words a random number between 10 and 9999

I am aware that we can generate a particular length using RandomStringUtils.randomNumeric(4) but not able to figure out how do I generate a random number between 2 different values

Thanks,

int randomInt = new Random().nextInt(9999 - 10 + 1) + 10

Thanks @Brandon_Hein This works for me.

Before your reply I was able to generate a random number between 10 and 9999 using excel and then calling that cell within the script because I was thinking no body I going to help me today. lol

More generally (for people reading this that want to use different bounds), the algorithm is:

new Random().nextInt(upperBound - lowerBound + 1) + lowerBound

There’s a tip waiting to be written, Brandon…

Or, if you prefer…

“Your mission, should you choose to accept it…”

Plus random strings/words, fixed character set…

[Brandon_Hein]

Maybe, although a lot of these are already topics in Stack Overflow. Maybe I will aggregate a bunch of these related topics into one tip in the Katalon context, like you mentioned.

You have the Java background, I don’t. It’ll certainly prove a worthy clearinghouse for me.

Here ya go

The Groovy/Java Utils Thread

After seeing several topics asking about the best ways to generate random data for use in web testing, @Russ_Thomas has recommended that a topic be created that can aggregate these techniques in one convenient place. So, here goes… Note: These were written to work alongside Katalon’s API, but be aware that all of these can be utilized outside of Katalon Studio, such as other Selenium-based tools, with the proper object translation. Also, please note that while these are all pure Java/Selenium/…

Thanks for the suggestion.
