Caused by: java.lang.ArrayIndexOutOfBoundsException: length=10; index=10

The indices in a 10-element array run from 0 to 9. You're trying to access element at index 10 that does not exist.

Simple fix is to change the random indexing with nextInt(11) to nextInt(10). For better future proofing, you can also make it nextInt(questionsArray.length).
