I have two ArrayList
. Each is of size 100000. I want to compare them and count matched elements.
Here's my code:
for (int i = 0; i < mArryLst2.size(); i++) {
if (ArryLst1.contains(mArryLst2.get(i))) {
matchedPixels++;
}
}
Here comparison process is taking lot of time.
How to solve and optimize this problem.
