> Could we add the method: removeElementAll to remove all the occurrences of
> the specified element from the specified
> (boolean/char/byte/short/int/long/float/double/Object) array:
> {code:title=org.apache.commons.lang3.ArrayUtils.java|borderStyle=solid}
> public static <T> T[] removeElementAll(final T[] array, final Object
> element) {
> int index = indexOf(array, element);
> if (index == INDEX_NOT_FOUND) {
> return clone(array);
> }
> int[] indices = new int[array.length - index];
> int count = 0;
> indices[count++] = index;
> for (;;) {
> index = indexOf(array, element, ++index);
> if (index == INDEX_NOT_FOUND) {
> break;
> } else {
> indices[count++] = index;
> }
> }
> return (T[]) removeAll((Object) array, Arrays.copyOfRange(indices, 0,
> count));
> }
> {code}
> or maybe better:
> {code:title=org.apache.commons.lang3.ArrayUtils.java|borderStyle=solid}
> public static <T> T[] removeElement(final T[] a, final Object element,
> boolean removeAll) {
> int index = indexOf(a, element);
> if (index == INDEX_NOT_FOUND) {
> return clone(a);
> } else if (!removeAll || index >= a.length - 1) {
> return remove(a, index);
> } else {
> int[] indices = new int[a.length - index];
> int count = 0;
> indices[count++] = index;
> for (;;) {
> index = indexOf(a, element, ++index);
> if (index == INDEX_NOT_FOUND) {
> break;
> } else {
> indices[count++] = index;
> }
> }
> return (T[]) removeAll((Object) a, Arrays.copyOfRange(indices, 0,
> count));
> }
> }
> {code}
