Processing Arrays
– Arrays and for loops are made for each other
– Loops are used to iterate over elements of an array
– For and For Each Loop
Passing Arrays to Methods
Returning Arrays from Methods
Arrays Utility classes
You can also pass arrays to custom methods
All of the arrays that I’ve demonstrated so far have been single-dimensional arrays, where the array has a fixed number of items and each item is an object of some kind, a string, a number, and so on.
In Java you can also create multidimensional arrays. These are arrays where each item in the array is also an array, and it’s a good way to store a matrix of information. I’ll show a demonstration of using multidimensional arrays using code to print mid left, mid center etc
java.util.Arrays
Lots of static methods
