java中for循环的最小和最大结果

Question

模拟篮球罚球表现和百分比。代码运行良好，但在最后的打印摘要中，我需要报告 5 场比赛的最高分和最低分。输出只需要说“最佳比赛罚球数：”+ 一个数字（最大值）。然后我也需要同样的东西来获得最差的比赛分数（分钟）。我想我需要从 for 循环结果中创建一个数组，但我不知道如何获得这样的功能。

import java.util.*;

public class Final2 {
public static void main(String[] args){
    int in = 0;
    double total_in = 0;
    int out;
    int count = 0;
    int games = 1;
    int tries;
    double average = 0;
    int total = 0;

        Scanner scan = new Scanner(System.in);
        System.out.print("Enter Player's Free Throw Percentage: ");
        int input = scan.nextInt();

        do{             
            System.out.println("\nGame " + games + ":");
            games++;

            for (tries = 0; tries < 10; tries++){
                int shot = (int)(Math.random()*100);
                count++;


                if (shot < input){
                   in++;
                    System.out.print("IN ");

                }   

                else{
                    System.out.print("OUT ");
                }               
            }
            System.out.println("\nFree Throws Made: " + in + " Out Of 10. ");
            total_in += in;
            in = 0;
        }   
        while (games <= 5);{
        }           
        average = (total_in / count)*100;

    System.out.println("\nSummary:");
    System.out.println("Best Game Free Throws Made: " + "???");
    System.out.println("Worst Game Free Throws Made: " + "???");
    System.out.println("Total Free Throws Made: " + String.format("%.0f", total_in) + " Out Of " + count);
    System.out.println("Average Free Throw Percentage: " + String.format("%.0f", average) + "%");       
    System.out.println("\nEND OF SIMULATION!");     
 }
}

Answer 1

不要想得那么复杂，作为不解决赋值的帮助：考虑为最小值和最大值使用变量。

Answer 2

每次在游戏循环中检查 in 是否大于您的“跑步最大值”（即 maxShots），是否 in 小于您的“跑步最小值”（即 minShots）。

还要注意如何初始化这些最大和最小变量。如果设置 minShots = 0，它可能会报告最小值为 0，即使实际最小值大于该值。这是因为当您检查 in 是否小于 minShots 时，0 将始终小于或等于 in。

import java.util.*;

public class Final2 {
public static void main(String[] args){
    int in = 0;
    double total_in = 0;
    int out;
    int count = 0;
    int maxShots = 0;
    int minShots = 10;
    int games = 1;
    int tries;
    double average = 0;
    int total = 0;

        Scanner scan = new Scanner(System.in);
        System.out.print("Enter Player's Free Throw Percentage: ");
        int input = scan.nextInt();

        do{             
            System.out.println("\nGame " + games + ":");
            games++;

            for (tries = 0; tries < 10; tries++){
                int shot = (int)(Math.random()*100);
                count++;


                if (shot < input){
                    in++;
                    System.out.print("IN ");

                }   

                else{
                    System.out.print("OUT ");
                }               
            }
            System.out.println("\nFree Throws Made: " + in + " Out Of 10. ");
            total_in += in;
            if(in > maxShots){
                maxShots = in;
            }
            if(in < minShots){
                minShots = in;
            }
            in = 0;
        }   
        while (games <= 5);{
        }           
        average = (total_in / count)*100;

    System.out.println("\nSummary:");
    System.out.println("Best Game Free Throws Made: " + maxShots);
    System.out.println("Worst Game Free Throws Made: " + minShots);
    System.out.println("Total Free Throws Made: " + String.format("%.0f", total_in) + " Out Of " + count);
    System.out.println("Average Free Throw Percentage: " + String.format("%.0f", average) + "%");       
    System.out.println("\nEND OF SIMULATION!");     
 }
}

按如下方式进行：

import java.util.Scanner;

public class Final2 {
    public static void main(String[] args) {
        int in = 0;
        double total_in = 0;
        int out;
        int count = 0;
        int games = 1;
        int tries;
        double average = 0;
        int total = 0;
        int worst = Integer.MAX_VALUE, best = Integer.MIN_VALUE;

        Scanner scan = new Scanner(System.in);
        System.out.print("Enter Player's Free Throw Percentage: ");
        int input = scan.nextInt();

        do {
            System.out.println("\nGame " + games + ":");
            games++;    
            for (tries = 0; tries < 10; tries++) {
                int shot = (int) (Math.random() * 100);
                count++;
                if (shot < input) {
                    in++;
                    System.out.print("IN ");
                } else {
                    System.out.print("OUT ");
                }
            }
            worst = Math.min(worst, in);
            best = Math.max(best, in);
            System.out.println("\nFree Throws Made: " + in + " Out Of 10. ");
            total_in += in;
            in = 0;
        } while (games <= 5);
        average = (total_in / count) * 100;

        System.out.println("\nSummary:");
        System.out.println("Best Game Free Throws Made: " + best);
        System.out.println("Worst Game Free Throws Made: " + worst);
        System.out.println("Total Free Throws Made: " + String.format("%.0f", total_in) + " Out Of " + count);
        System.out.println("Average Free Throw Percentage: " + String.format("%.0f", average) + "%");
        System.out.println("\nEND OF SIMULATION!");
    }
}

测试运行：

Enter Player's Free Throw Percentage: 60

Game 1:
OUT OUT IN IN OUT IN OUT IN IN OUT 
Free Throws Made: 5 Out Of 10. 

Game 2:
IN IN OUT IN OUT IN OUT IN OUT IN 
Free Throws Made: 6 Out Of 10. 

Game 3:
IN OUT IN IN IN OUT IN IN OUT OUT 
Free Throws Made: 6 Out Of 10. 

Game 4:
OUT IN IN IN IN OUT OUT IN IN IN 
Free Throws Made: 7 Out Of 10. 

Game 5:
IN IN IN IN OUT IN OUT OUT OUT OUT 
Free Throws Made: 5 Out Of 10. 

Summary:
Best Game Free Throws Made: 7
Worst Game Free Throws Made: 5
Total Free Throws Made: 29 Out Of 50
Average Free Throw Percentage: 58%

END OF SIMULATION!
