Working with arrays
If you only need two variables in your sketch, it's ok to declare them as two different float or int variables. But, if you need lots of variables, this might not be the best option. In this case, you'll need to use an array. An array is basically a collection of variables of the same type. In this recipe, we'll cover how you can work with the functions Processing offers for working with arrays.
How to do it...
The first thing we'll do is to declare two arrays of floats and assign some values to them. You can easily do this by adding curly braces around a series of comma separated numbers.
float[] array1 = { 1.0, 4.7, 3.08 };
float[] array2 = { 72.86, 48.32 };
void setup()
{
noLoop();
}Inside the draw() function, we'll print the output of the functions to the console. The first thing we'll do is add an extra number to the first array by using the append() function.
println( "New Array: Array 1 + new float" ); println( "------------------------------"); float[] newArray...
