Revision of Arrays

Useful Methods of the Array Class

Method	Description
copyOf(array, newSize)	returns a copy of the array with the given size
copyOfRange(array, startIndex, endIndex)	returns a copy of the selection specified of the given array - from startIndex (inc) to endIndex (excl)
equals(array1, array2)	returns true if the arrays contain the same elements
fill(array, value)	sets every element of the array to the given value
sort(array)	rearranges the elements of the array so they appear in non-decreasing order
toString(array)	retuns a String representation of the array, as in [3, 5, 7]

So the way to compare Arrays is the same as comparing Strings - instead of using ==, you need to use Arrays.equal. I assume this is true for everything that isn't a primitive data type.
