About Arrays

Arrays should be used for variables that have something to do with each other. Basically, arrays are a list of variables, and arrays are a variable themselves. Here is how to make an array

[class][] [variable-name];
//Or...
int[] myInts;

To specify the length of an array:

myInts=new int[LENGTH];
//Put into one statement
int[] myInts = new int[LENGTH];

LENGTH = array size. It is simply how many items are in the array.

You need to initialize each part of the array. To "access" the members of the array:

myInts[2]==5;
int temp = myInts[3];

Note: Do NOT use arrays when the members have nothing to do with each other. This causes messy code! =Basic Tips for Improving Code
