create a stack class based on an array of type double of fixed size. In the class,

The array should have the default size of 5.

The array size should be settable via a constructor.

The following methods must be implemented:

push inserts a value a the top of the stack

pop returns the top value, removing it from the stack

isEmpty returns true if the stack is empty, false otherwise

isFull - returns true if the stack is full, false otherwise

Please notice you must use an array not an arraylist or any other list. Im having trouble with a couple parts of it. Thanks

Also use java
