在外部循环运行我的程序1000次并保持计数 - Java

标签: java loops

我以前有一些基本的java技能但是自从我使用它们已经有几年了。我的程序会执行我想要的一切,但是我需要它来运行程序1000次,并保持rtCorrectrtIncorrect的总计。这两个总数实际上是我最终需要的唯一东西(即我只需要最后评论的声明)。我不确定我是否应该在我的main方法中添加一个外部循环,或者我是否应该有一个单独的方法。我并不担心它很漂亮所以我宁愿只用一个简单的循环在main方法中完成所有操作。

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);

    }

}

以下是我的尝试:

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);
        }

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);


    }

}

这些都没有给我我需要的东西。第一个只打印出程序的一次迭代1000次,第二次给我一个RT的34000或者它在一次迭代x 1000上得到的任何RT,另一个转换为0

答案 0 :(得分:2)

要么。我建议(因为你是新手)只是在你的代码周围放一个for循环,当它工作时,如果你愿意,可以将它重构成单独的方法。

如果你将它重构为一种新方法,我建议你在main()

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

然后让runProgram()执行循环,并对已有的东西执行另一种方法,并将当前的Tally保持为MyClass的成员变量。避免链接大量静态调用并且必须具有返回值。

好的......这一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){
                    ...

在这种情况下,因为您知道代码循环的频率,所以使用for loop。语法如下:

for(counter; termination condition; incremental step)

例如:

for(int x = 0; x < 1000; x++)

在你的代码的上下文中,你只需将它包装在你的方法中,如下所示:

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

 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;
                }
   }
}

然后,当代码完成后,打印出你的值,你就会得到1000个案例的抽样数据,虽然从更科学的角度来说,如果你是为论文写这个,那么你就是处理PRNG(伪随机数生成器)然后你想要一个比它更大,更大的采样帧。 :)
