HashMap: get arraylist to be a set of key or value
<p>I have two arraylists A1, A2. Each element of A1 would be the key and each element of A2 the corresponding value. So the solution that I found is looping on A1 ( A1 and A2 have the same size) making hashmap.add(A1[i],A2[i]) but is there a way to directly send the key value pairs as two sets? I want to avoid loops it is going to slow my code..Thank you in advance!</p>
