Array Declaration

• An Array in Processing

• • looks a like a regular variable, but is declared using the brackets “[ ]” to denote that it is an a list, rather then a single variables
  • • ex: int [ ] numbers;
  • can hold any type of data ... ints, floats, colors, etc ...
  • • ex: float [ ] pos; color [ ] rainbow; ... etc
  • must be initialized with the new command, which tells Processing how many variables are in the array
  • • ex: int [ ] numbers = new int[3];
  • the elements in the list are indexed from 0 to the length-1
  • • ex: int[0] = 0; // means the first element is = 0
  • has a built in value that returns the length of the array
  • • number.length // returns an int numebr of elements in the array
