如何使变量最大和最小连续识别不同的数字输入。而不是只识别最后的输入。 [英] How Do I Make The Variables Max And Min Continuously Recognize The Different Inputs Of Num. Instead Of Only Recognizing The Last Input.

问题描述

/**
 * Write a description of class MinimumMaximum here.
 *
 * @author (your name)
 * @version (a version number or a date)
 */
import java.util.Scanner;
public class MinimumMaximum
{

    public MinimumMaximum()
    {
        Scanner number = new Scanner(System.in);
        int min=0, max=0, lcv = 0, num, num1;
        String maxmin;

          while ((lcv < 10) && (lcv >= 0))
        {
            lcv++;
            System.out.print("Please enter a number: ");
            num = number.nextInt();
            max = max(max,num);
        min = min(min,num);
        }










        maxmin= maxmin(max,min);
        System.out.println(maxmin);


    }


    public int max(int max, int num)
    {


        max = 1;




            if (num > max)

            max = num;

           else

           max = max;




    return max;
}

 public int min(int min,int num)
    {



        min = 0;



            if (num < min)
            min = num;

           else if (min > num)
           min = min;

        return min;
    }










    public String maxmin(int max, int min) {
        String maxmin = "The greatest value is " + max + " and the lowest value is "  + min + ".";
        return maxmin;
}

}

推荐答案

检查变量命名。你搞砸了很多最大和分钟。



你可以用this来引用类变量。



你也搞砸了返回值和引用：你按值传递max然后你返回那个值。

那太多了。传回或分配值：

Check your variable naming. You messed up there, to much "max" and "min".

You can reference the class variable with "this.".

also you messed up with return values and references: You are passing the "max" by value and then you return that value.
That is too much. Pass back OR assign values:

private void isMax(int num) // no return value
{
  if (num > this.max){
     this.max = num;
  }
}
 
public int min(int min,int num) // with return value
{
  if (num < min){
    return num;
  }
  return min; // default return
}

请选择一个版本并重写另一个版本。
