我需要找到用户输入的特定变量，但我不理解如何

    Scanner scan = new Scanner(System.in);
    int amount = 0;
    int input = 0;
    int[] numbers =  new int [amount];

    for(int i = 0; i<1; i++ )
    {
        System.out.println("How many numbers do you plan to enter?");
        amount = scan.nextInt(); 
        if (amount==amount)
        {
            for(int x = 0; x<amount; x++)
            {
                System.out.println("Enter a number");
                input = scan.nextInt();
                input = input + input;

            }
        }

    }
    double average = input/amount;
    System.out.println(average);
    Scanner scan = new Scanner(System.in);
