FilterArrayUtil.filtermethod is used to edit an existing array element, only for a generic array operation, and the original type array is not provided. The editor interface in the method is used to return the edited value of each element, and returns NULL when this element is discarded.Example: Filtering an array, preserving only an even number integer[] a = {1, 2,3,4,5, 6};integer[] filter = Arrayutil.filter (A, new Editor @Override public Integer edit (Integer t) {return (t% 2 = 0)?
