java - 外部循环运行我的程序 1000 次并保持计数 - Java

Question

我曾经有一些基本的java技能，但我已经有几年没有使用它们了。我的程序一次就能完成我想要的所有操作，但我需要它运行该程序 1000 次并保留 rtCorrect 和 rtIn Correct 的总数。这两个总数实际上是我最终需要的唯一东西(即我只需要最后注释掉的语句)。我不确定是否应该在主方法中添加外部循环，或者是否应该有一个单独的方法。我并不担心它是否漂亮，所以我宁愿在主方法中用一个简单的循环来完成这一切。

import java.util.Random;

public class Thesis {

        public static void main (String [] args){

        int correct = 0;
        int incorrect = 0;
        int rtCorrect = 0;
        int rtIncorrect = 0;


            while(correct<20 && incorrect<20){
                    Random rand = new Random();
                    int pickedNumber = rand.nextInt(100);
                    if (pickedNumber<52){
                        correct++;
                    }
                    else if (pickedNumber>51){
                        incorrect++;
                    }
                    if (correct == 20){
                        rtCorrect = rtCorrect + correct + incorrect;
                    }
                    else if (incorrect == 20){
                        rtIncorrect = rtIncorrect + incorrect + correct;
                    }
                }

        }
        System.out.printf("Correct: %d Incorrect: %d", correct, incorrect);
        System.out.printf ("\nCorrect Response Time: %d\nIncorrect Response Time: %d", rtCorrect, rtIncorrect);
        //System.out.printf ("\nTotal Correct RT's: %d \nTotal Incorrect RT's: %d", totalRTCorrect, totalRTIncorrect);

    }

}

这是我尝试过的:

import java.util.Random;

public class Thesis {

        public static void main (String [] args){

        int correct = 0;
        int incorrect = 0;
        int rtCorrect = 0;
        int rtIncorrect = 0;


        for (int j = 0; j < 1000;j++){
            int totalRTIncorrect = 0;
            int totalRTCorrect = 0;

            while(correct<20 && incorrect<20){
                    Random rand = new Random();
                    int pickedNumber = rand.nextInt(100);
                    if (pickedNumber<52){
                        correct++;
                    }
                    else if (pickedNumber>52){
                        incorrect++;
                    }
                    if (correct == 20){
                        rtCorrect = rtCorrect + correct + incorrect;
                    }
                    else if (incorrect == 20){
                        rtIncorrect = rtIncorrect + incorrect + correct;
                    }
                }

                totalRTIncorrect = totalRTIncorrect + rtIncorrect;
                totalRTCorrect = totalRTCorrect + rtCorrect;
                System.out.printf ("\nTotal Correct RT's: %d \nTotal Incorrect RT's: %d", totalRTCorrect, totalRTIncorrect);
        }

和

import java.util.Random;

public class Thesis {

        public static void main (String [] args){

        int correct = 0;
        int incorrect = 0;
        int rtCorrect = 0;
        int rtIncorrect = 0;
        int totalRTIncorrect = 0;
        int totalRTCorrect = 0;

        for (int j = 0; j < 1000;j++){

            while(correct<20 && incorrect<20){
                    Random rand = new Random();
                    int pickedNumber = rand.nextInt(100);
                    if (pickedNumber<52){
                        correct++;
                    }
                    else if (pickedNumber>52){
                        incorrect++;
                    }
                    if (correct == 20){
                        rtCorrect = rtCorrect + correct + incorrect;
                    }
                    else if (incorrect == 20){
                        rtIncorrect = rtIncorrect + incorrect + correct;
                    }
                }

                totalRTIncorrect = totalRTIncorrect + rtIncorrect;
                totalRTCorrect = totalRTCorrect + rtCorrect;
        }
        System.out.printf ("\nTotal Correct RT's: %d \nTotal Incorrect RT's: %d", totalRTCorrect, totalRTIncorrect);
        //System.out.printf("Correct: %d Incorrect: %d", correct, incorrect);
        //System.out.printf ("\nCorrect Response Time: %d\nIncorrect Response Time: %d", rtCorrect, rtIncorrect);


    }

}

这些都没有给我我所需要的。第一个仅打印出程序的一次迭代 1000 次，第二个给我一个 RT 为 34000 或在一次迭代中达到的任何 RT x 1000，另一个 RT 为 0

Answer 1

要么。我建议(因为您是新手)在代码中放置一个 for 循环，当它起作用时，如果您愿意，可以将其重构为单独的方法。

如果你将其重构为一个新方法，我建议在你的 main() 中进行

 MyClass myclass = new MyClass();
myclass.runProgram();

然后让 runProgram() 执行循环，并对您已有的内容使用另一种方法，并将当前计数保留为 MyClass 的成员变量。避免链接大量静态调用并必须有返回值。

好的...这部分是为了解决以下评论:

    public static void main (String [] args){


            int totalRTIncorrect = 0;
            int totalRTCorrect = 0;

            for (int j = 0; j < 1000;j++){

                int correct = 0;
                int incorrect = 0;
                int rtCorrect = 0;
                int rtIncorrect = 0;

                while(correct<20 && incorrect<20){
                    ...
