• If you want to know whether an class-instance-containing array has been assigned a value at a specified position, then instantiate the following pattern:

  array name[index] == null 
  

• If you have a value stored in an array at a specified position, and you want to read that value, then instantiate the following pattern:

  array name[index] 
  

• If you want to know the length of an array, then instantiate the following pattern:

  array name.length
