If you don't understand arrays, you don't know basic Java. How would you make a chatting app knowing next to nothing about java?

They are used for generic access in loops. I.e. pretend you have 5 strings. You want to perform the exact same methods on them. Without an array, you would have to write out all the accesses to the functions. With the array, you could simply use a for loop for each function call so you only have to write it once.
