Java中for循环的最小和最大结果
模拟篮球罚球表现和百分比。代码工作正常，但是在最后的打印摘要中，我需要报告5个游戏中的最高得分和最低得分。输出只需要说“最佳游戏罚球次数：” +一个数字（最大值）。然后，我也需要同样的东西来获得最差的游戏分数（分钟）。我想我需要从for循环结果中创建一个数组，但是在如何获得类似功能方面迷茫了。
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!");
}
}

如下进行：
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!
