Getting dynamic with arrays

As we discussed at the beginning of all this array discussion, if we need to declare and initialize each element of an array individually, there isn't a huge amount of benefit to an array over regular variables. Let's look at an example of declaring and initializing arrays dynamically.

A dynamic array example

Let's make a really simple dynamic array example. You can get the working project for this example in the download bundle. It is located at Chapter 13/Dynamic Array Example/MainActivity.java.

Create a project with a blank Activity and call it Dynamic Array Example.

Type the following just after the call to setContentView in onCreate. Check whether you can work out what the output is before we discuss it and analyze the code:

// Declaring and allocating in one step
int[] ourArray = new int[1000];

// Let's initialize ourArray using a for loop
// Because more than a few variables is a lot of typing!

for(int i = 0; i < 1000; i++){

   // Put the value of ourValue...
