应该提示用户输入几个整数，并将它们存储到数组，然后按向前和向后的顺序打印这些整数。

 
      final int EMPLOYEES = 3;
      int[] hours = new int[EMPLOYEES];
      Scanner keyboard = new Scanner(System.in);
      System.out.println("Enter the hours worked by"+ " " + EMPLOYEES + " " + "employees.");
      System.out.print("Employee 1:");
      hours[0] = keyboard.nextInt();
      System.out.print("Employee 2:");
      hours[1] = keyboard.nextInt();
      System.out.print("Employee 3:");
      hours[2] = keyboard.nextInt();
      System.out.println("The hours you enter are:");
      System.out.println(hours[0]);
      System.out.println(hours[1]);
      System.out.println(hours[2]);
    }

我们也可以使用循环来实现这个程序的运行：

        
        final int EMPLOYEES = 6;
          int [] hours = new int[EMPLOYEES];
          Scanner keyboard = new Scanner(System.in);
          System.out.println("Country name and population");
          for (int index = 0; index<EMPLOYEES; index++)
          {
              System.out.print("Employee" + (index + 1) + " : ");
              hours[index] = keyboard.nextInt();
          }
          System.out.print("The hours you entered are:");
          for(int index = 0; index<EMPLOYEES; index++)
              System.out.println(hours[index]);
    }
