Question

在无限循环中，我如何打印一个随机数会增加每一组次数（例如10次）？这是我目前的代码。

`import hsa.*;
 public class MidTermProject{
   public static void main(String[] args){
     Console con = new Console();

     int intCount;
     int intRand;
     int intAnswer;
     int intRand2;
     int intTotal;
     int intSubtractTotal;
     int intAnswer2;
     int intRand3;
     int intRand4;
     int intQuestionsAsked;
     int intTotalQuestions;
     int intTRand;
     int intTRand1;
     int intTRand2;
     int intTRand3;
     int intTRand4;
     double dblTotalScore;
     double dblScore;

    dblScore = 0;
    intQuestionsAsked = 0;   

//5 - Math Training Game     

con.println("This is the Math Training Game. The Questions will increase difficulty.");
con.println("There will be 30 Questions in Total");
con.println("");
con.println("One Digits:");
con.println("");

//Loop ---------------------------------------------------------------------

for(;;){
  for(intCount=0; intCount<5;intCount++){

    //----------------------------------------------------------------------------
    //1 DIGITS

    intRand=(int)(Math.random()*9+1);

    intRand2=(int)(Math.random()*9+1);

    intTotal = intRand + intRand2; 

    intRand3 =(int)(Math.random()*9+1);

    intRand4 =(int)(Math.random()*9+1); 

    intSubtractTotal = intRand3 - intRand4;

    con.println("What is " + intRand + " + " + intRand2);
    intAnswer = con.readInt();

    if(intAnswer == intTotal){

      con.println("Correct");
      con.println("");

      //Add score 

      dblScore = dblScore + 1;
      intQuestionsAsked = intQuestionsAsked + 1; 

    }else{
      con.println("Wrong");
      con.println("");

      intQuestionsAsked = intQuestionsAsked + 1;
    }
    // SUBTRACTION ---------------------------------------------------------

    con.println("What is " + intRand3 + " - " + intRand4);
    intAnswer2 = con.readInt();

    if(intAnswer2 == intSubtractTotal){
      con.println("Correct");
      con.println("");

      //Add Score -------------------------------------------------------------

      intQuestionsAsked = intQuestionsAsked + 1;
      dblScore = dblScore + 1;

    }else{
      con.println("Wrong");
      con.println("");

      intQuestionsAsked = intQuestionsAsked + 1; 

    }  

    intTotalQuestions = intQuestionsAsked;

    //----------------------------------------------------------

    while(intTotalQuestions == 10){


      intQuestionsAsked = 0;  
      intTRand =  intRand * 10;
      intTRand2 = intRand2 * 10;
      intTRand3 = intRand3 * 10;
      intTRand4 = intRand4 * 10;

      con.println("What is " + intRand * intTRand + "+" + intTRand2 * intRand2);
      intAnswer = con.readInt();

      con.println("What is " + intRand2 * intTRand2 + "-" + intRand3 * intTRand3);
      intAnswer2 = con.readInt();

    }        
    //--------------------------------------------           
  }
 } 
 }    
}'

有人能告诉我我做错了什么以及如何修复此代码以使其正常工作？

Answer 1

我的理解是你想要生成越来越高的随机数。存储先前随机生成的值。从您想要的任何范围生成新的随机数，并添加以前的数字以确保它增加。此外，由于看起来您的代码比以前更笨拙，我建议using arrays减少您拥有的所有过多实例变量。

Answer 2

让程序永远运行是糟糕的设计。

话虽如此，如果您希望每次设置范围时随机数都更大，

(min + (int)(Math.random() * ((max - min) + 1)));

并在每次迭代时增加min和max。

如何在java中每隔一定次数增加一个随机数？
