Splitting of a String into a multiple element list in Java

Question

I have a String "Student1Student2Student3" for example, is there anyway i can turn this String into a list with three elements eg ["Student1", "Student2", "Student3"]?

The above string is just an example, "Student1" could be a random name of variable length. Thanks in advance.

Answer 1

Based on your comment

I think in the final code it would be ideal to split on a lowercase letter followed by an uppercase letter.

it looks like you are looking for split("(?<=[az])(?=[AZ])") .

Look-around mechanisms are zero-length which means they don't include in matched (in delimiter) characters they ware suppose to test. This will allow us to test lower-case character from left and upper-case from right but not consume it while splitting (since they will not be included in match).

Answer 2

You can use the regex ([a-zA-Z]+[0-9]+) to match specific parts of the string (for example in the string Student1Student2Student3 , the first match would be Student1 , and then Student2 .

Here's a hint, use the Pattern class and the Matcher class

:) hopefully it will be enough to help you out.
