    split() is a String method. It is used in lots of code posted on the forum. Do a search for some examples.

    The are many examples given in the API doc for the split() method that use simple Strings.
    Look at some of them and see if the String you want to split has anything like what the examples show.

    regex stands for regular expression. That's something you'll not want to worry about for a while.

    Did you try the simple example you found? What happened?

    There are lots of tutorials on how to write regular expressions. Follow the links in the String class's API doc
    and ask google.

    do I type "regex" or is that a descriptive placeholder representing the actual delimter I wish to use?
    The API doc shows that the arg to the split method is a String named regex. Read the API doc for a description of the variable: regex in the Parameters: section.

    An easy way to see array contents:
    System.out.println("an ID "+ java.util.Arrays.toString(theArrayName));
