How do I get the number of characters from a variable.

    #set($test1 = "ABCD")
    #set($test2 = "EFG")

What I would like to get is :
    4 for the $test1 variable since there are 4 characters
    3 for the $test2 variable since there are 3 characters

If this is not possible, is there a way I can get the first character of each variable so i would get :
    "A" for $test1
    "E" for $test2

    Because the variable is a Java String, you can utilize any of the class' methods.

    For instance, to obtain the length of the variable, you can use:

    #set($test1 = "ABCD")

    And, to get the first character, you can use:

    #set($test1 = "ABCD")

    Please let me know if you have any questions.
