OK I've done something now. It's difficult to see how you can do this without any input prompts at all but if you think I've done too much just take them out: /* The program examines each of the 'n' elements of the array in turn. If it's even it examines the next element If it's odd it looks through the remaining elements until it finds one (if any) which is even and swaps the two around. The minimum number of recursions will be none if all array elements are odd. The maximum number of recursions will be n - 2 if at least 6 array elements are even. */ import java.util.Scanner; public class Problem3 { private static int start = 0; public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); System.out.print(How many integers are to be entered : ); int number = keyboard.nextInt(); System.out.println(); if (number { System.out.println(Must be a positive number); return; } System.out.println(Enter  + number +  numbers); int[] ia = new int[number]; for(int i = 0; i { ia[i] = keyboard.nextInt(); } System.out.println(); ia = evenBeforeOdd(ia); for (int i : ia) { System.out.print(i +  ); } } private static int[] evenBeforeOdd(int[] ia) { for(int i = start; i { if (ia[i] % 2 == 0) { if (i > start) { int temp = ia[i]; ia[i] = ia[start]; ia[start] = temp; } start++; if (start { ia = evenBeforeOdd(ia); } break; } } return ia; } }
