• object is a base class which may be used to store references to objects of any class.

• Strings can be indexed as arrays.

• Arrays are indexed lists of any base type or any class type including GameObjects.
• Arrays are declared using these statements

Train[] trains;
int[] Numbers = new int[n]; // where n is the number of items in the array.

• The keyword new creates the array but does not initialise any of the members

Numbers[3] = 256; // assigns a value to the array. Array indices start at zero

• Arrays may also be returned by methods

Signal[] signals = World.GetSignalList()  // creates an array of signals from a built in method
Numbers[Numbers.size()] = 5;              // adds a new value after the end of the array, increasing its size by 1
Numbers[0,1] = null;                      // deletes the first value from the array, decreasing its size by 1
