Does the union() function preserve the order of the items passed to it?
I suspect not, given that Java Sets don't preserve order...

Hi mike,
Yes , the union() function preserves the order of items we passed as input.
Lets say, if we pass two arrays as input array 1 and array 2.
It gives the unique values from the array 1 and appends the unique values from array 2 in the same order we gave.
