Array Declarations

• Arrays can hold primitives or objects, but the array itself is always an object.
• When you declare an array, the brackets can be to the left or right of thevariable name.
• It is never legal to include the size of an array in the declaration.
• An array of objects can hold any object that passes the IS-A (or instanceof) test for the declared type of the array. For example, if Horse extends Animal, then a Horse object can go into an Animal array. Static Variables and Methods
• They are not tied to any particular instance of a class.
• No classes instances are needed in order to use static members of the class.
• There is only one copy of a static variable / class and all instances share it.
• static methods do not have direct access to non-static members.
