How to delete the last element from an array?

Since in Java, arrays are non-resizable, you will have to copy everything into a new, shorter array.

Arrays.copyOf(original, original.length-1)

I know its a very old thread. Still the approved answer itself didn't work for me. And this is how I resolved it.

Create a method like this:

String[] sliceArray(String[] arrayToSlice, int startIndex, int endIndex) throws ArrayIndexOutOfBoundsException {    if (startIndex < 0)        throw new ArrayIndexOutOfBoundsException("Wrong startIndex = " + startIndex);    if (endIndex >= arrayToSlice.length)        throw new ArrayIndexOutOfBoundsException("Wrong endIndex = " + endIndex);    if (startIndex > endIndex) { // Then swap them!        int x = startIndex;        startIndex = endIndex;        endIndex = x;    }    ArrayList<String> newArr = new ArrayList<>();    Collections.addAll(newArr, arrayToSlice);    for (int i = 0; i < arrayToSlice.length; i++) {        if (!(i >= startIndex && i <= endIndex)) // If not with in the start & end indices, remove the index            newArr.remove(i);    }    return newArr.toArray(new String[newArr.size()]);}

Then called it like this:

String lines[] = {"One", "Two", "Three", "Four", "Five"};lines = sliceArray(lines, 0, 3);

This will result in:

"One", "Two", "Three", "Four"

Now I can slice the array in whichever way I want!

lines = sliceArray(lines, 2, 3);

This will result in:

"Three", "Four"

    @Test    public void removeLastElement() {    String[] lastElementRemoved = { "one", "two", "three" };    String[] removedElement = Arrays.copyOf(lastElementRemoved, 2);    System.out.println(Arrays.toString(removedElement));    }
