使用记事本在Java中添加

class Addition
{
   public static void main(String[]args)
  {
    int x, y, z;
    System.out.printIn("Enter two integers to calculate their sum");
    Scanner in = new Scanner(System.in);
    x = in.nextInt();
    y = in.nextInt();
    z = x + y;
    System.out.printIn("Sum of enetered Integers="+z);
   }
}

在代码中,有人能解释一下吗? 这将是明智的
