    Default copying and comparing stacks

    How would I create a shallow copy of a stack? The interface method which I must implement is:
    	MyStackInterface<T> copy();
    	// Returns a shallow copy of this stack

    It doesn't make sense to me that I return an interface....

    The other method that I must implement is:
    	boolean equals(MyStackInterface<T> s);
    	// Returns true if the contents of this Stack are equal to the contents of s
    	// Does not change the contents of s.

    Can anyone help me please?

    Are you looking for

    Thread.currentThread().getStackTrace();

    This will return an array of [StackTraceElement]s.
