android - reverse the order of an array
I have an array of objects.
Is it possible to make a new array that is a copy of this array, but in reverse order? I was looking for something like this.
// my array
ArrayList<Element> mElements = new ArrayList<Element>();
// new array
ArrayList<Element> tempElements = mElements;
tempElements.reverse(); // something to reverse the order of the array
You can do this in two steps:
ArrayList<Element> tempElements = new ArrayList<Element>(mElements);
Collections.reverse(tempElements);
Kotlin
val reverseList: List<Int> = yourActualList.reversed();
