  int[] array2 = new int[5];
  BufferedReader in = new BufferedReader(new InputStreamReader(;
  System.out.println("Enter 5 numbers for the first Array : ");
  for(int i = 0; i < array1.length; i++){
  array1[i= Integer.parseInt(in.readLine());
  System.out.println("Enter 5 numbers for the second Array : ");
  for(int i = 0; i < array2.length; i++){
  array2[i= Integer.parseInt(in.readLine());
  catch(NumberFormatException ne){

  boolean check = Arrays.equals(array1, array2);
  if(check == false)
