Velocity Variable(use together string and integer variables)


How can I use String and Integer variables it together in "Velocity"?

#set ($var1 = "exp"+1)

I tried a few times but I could not.

Any help will be highly appreciated.


Solution

  • If you were trying to do concatenation, it's not supported by Velocity, not even for 2 Strings. Instead, you should use string interpolation. Example:

    #set ($string = "exp")
    #set ($number = 1)
    #set ($interpolatedExample1 = "$string$number")
    #set ($interpolatedExample2 = "${string}someStringLiteral$number")
