Answer 1

Also as a minor enhancement.

The main reason for the try/catch block is that e1 could be null for the initial movement. in addition to the try/catch, include a test for null and return. similar to the following

if (e1 == null || e2 == null) return false;
try {
...
} catch (Exception e) {}
return false;
