When we execute the test above, it passes. As we’ve seen, we’ve passed theaListobject to thereversemethod, and then the order of the elements in theaListobject gets reversed. In case we don’t want to change the originalList, and expect to get a newListobject to contain the element...

This method reverses the elements in a list, so we must convert the array into a list first by using java.util.Arrays.asList(array) and then reverse the list. It will reverse the backing array items as well. Note that the reverse() method reverses the order of the items in the ...
