I want to delete the selected element in an array in java

Question

I want to delete the selected element in an array in java, for example deleting 3,5,8 in

int[]={3,2,5,6,4,8,9}

an array is a fixed length, you want either to use an arraylist (which is not fixed length) or create a new int[] — Richard Tingle, Nov 27 '13 at 08:58
`int[index] = 0;` remove you replace with 0 or use `ArrayList`. — Subhrajyoti Majumder, Nov 27 '13 at 08:59

You can't. Arrays have a fixed length, and the only way to "delete" them would be to either use for example zero to mark a "deleted" entry, or to create a new smaller array and copy all but the "deleted" entries there.

You can use it :

array = ArrayUtils.removeElement(array, element)

Use ArrayUtils class to remove an element

 array = ArrayUtils.removeElement(array,element)

Arrays cannot be resized, so you either create a new array and copy the desired elements from the old one (use System.arraycopy(..)) for that, or better: use a Collection such as ArrayList or LinkedList.
