I keep getting a 'null value' in the allActivitiesLecturerLookupField[counter] memory locations instead of a lecturer's name. Why is this? All arrays have the correct information in them. What is wrong with my code?

Have you tried using a debugger or output statements so that you can actually see how things are running? I'd assume that the if statement never evaluates to true, so you're left with the initial null values.

Yes it prints out null 5 times. But i dont understand why.
Unless the two objects point to the same reference in memory, the expression will always be false and hence, never assign the value. I am guessing you want to use the .equals() method instead of == to test whether the objects are equivalent (data-wise) rather than pointing to the same reference in memory.
