I have two Long array elements and both have some values
Long[] firstArray = new Long[10]; Long[] secondArray = new Long[25];
Both the array may or may not be equal in size.
firstArray[0] = new Long("1"); firstArray[1] = new Long("2"); firstArray[2] = new Long("3"); secondArray [0] = new Long("2"); secondArray [1] = new Long("3");
I want to compare the secondArray
with firstArray
and create a new thirdArray
with the values which are not in secondArray
.
In the above example the thirdArray
will have only 1
Answer
One possible solution would be to convert both of your arrays to List and use removeAll
:
Long[] firstArray = new Long[10]; Long[] secondArray = new Long[25]; firstArray[0] = new Long("1"); firstArray[1] = new Long("2"); firstArray[2] = new Long("3"); secondArray [0] = new Long("2"); secondArray [1] = new Long("3"); List<Long> first = new ArrayList<>(Arrays.asList(firstArray)); List<Long> second = Arrays.asList(secondArray); first.removeAll(second); Long[] thirdArray = first.toArray(new Long[first.size()]);
