Answer 1

It's because you start at the i index of the array, so when it gets to the number 2 in the array (which has the index 2), x starts from 2, but in the second array, it's index is 0, so it can't be found. In the second loop you have to start x from 0

Answer 2

// for(int x = i;x < arr2.length;x++){
for(int x = 0;x < arr2.length;x++){ // x=0
