QUESTION
For an online java course, I'm coding the Caesar Cipher. Here, you input a string and a shift number, and the answer returns with the shifted string, where all the characters are shifted "down" the alphabet by the shift number. For my program, I also have a grouping exercise, where I have to group the shifted string into groups of a certain number (ex: "SGHSJDGDKGHSA" grouped by 3 is "SGH SJD GDK GHSA"). If the number of characters in the string is not divisible by the grouping number, then the program adds lowercase x's to the end of the string (ex: "SGHSJDGDKGHSA" grouped by 4 is "SGHS JDGD KGHS Axxx").
My program works until the grouping function (the groupify method in my code). The string with the groups is not returned. Any advice on how to fix this?

is defined but never initialised, hence sbShiftText.length()
is not valid.
It should be like this:
StringBuilder sbShiftText = new StringBuilder(shiftText);
