无法获得方法的输出

Question

我是Java新手，在使用方法时遇到麻烦。我正在尝试显示确定方法AndreDisplay，但是我尝试过的方法不起作用。当我把东西放在main中的defineAndDisplay（）的括号中时，我得到一个错误。我不确定自己出了什么问题，任何指导都将对您有所帮助，谢谢！

public static void determineAndDisplay(Scanner userInput, int pNum) 
    {
         //variables
      int count = 0, high = 0, low = 0;

      //loop
      while(true){

        System.out.print("Enter an integer, or -99 to quit: --> ");
        pNum = userInput.nextInt();

        if(pNum == -99)
        {
            break;
        } //if end
        count++;

        if(count == 1)
        {
            high = pNum;
            low = pNum;
        } //if end

                //highest
        if(pNum > high)
        {
           high = pNum; 
        } //if end

        //smallest
        if(pNum < low)
        {
            low = pNum;
        } //if end


        } //while end

        if (count == 0)
        {
     System.out.println("\nYou did not enter any numbers.");
        } //if end
        else
        {
     System.out.println("\nLargest integer entered: " + high);
         System.out.println("Smallest integer entered: " + low);
        } //else end
    } // determineandDisplay end

    public static void main(String[] args) {
      // start code here

    Scanner goGet = new Scanner(System.in);
        String doAgain = "Yes";

        while (doAgain.equalsIgnoreCase("YES")) {
            // call method
            determineAndDisplay();

            // repeat
            System.out.print("\nEnter yes to repeat --> ");
            doAgain = goGet.next();
        } //end while loop


    } // main end

Answer 1

public class MainClass{

 public static void determineAndDisplay(Scanner userInput, int pNum){

  // your code

 }

 public static void main(String[] args){

  // your code

 }

}

此外，请确保您的main方法始终位于与代码文件同名的公共类中。另外，请确保已导入扫描仪。
