There is no need to copy elements over to another array. Just assume that elements 0 ... i1 are in sorted order and assume the length of the array is n. If i < n1 and elements i1 and i are in sorted order call your method recursively for the next elements. Otherwise if i == n1 the entire array is ... 
Then you will probably need to create a new array for each intersection and using nested for loops add items to your arrays depending on whether they are in one array and not in another by checking in an ifblock. First work out what you would do on paper, then translate this to java. It's not hard once you see the ...
