Question

请看一下这个主题： Can I calculate the average of these numbers? 我怎么能为此编写程序？在正确的答案中，他只是在没有java程序的情况下编写了方程式，并且他使用了例如newValue而没有初始化newValue。这是等式：

int currentScore = (currentScore * currentCount + newValue) / currentCount;

Answer 1

请找到如下的步骤：

   private float calculateNewScore(){
        float currentScore = 6.1123
        int currentCount = 12;
        float newValue = 4.5;
        int newCount = currentCount+1;

        float newScore = (currentScore * currentCount + newValue) / newCount ;

    }

如果您正在寻找示例程序，它可以是这样的：

 public class CalculateScore {

  public static void main(String[] args) {
    float currentScore = 6.1123; //you can initialize with any desired value
    int currentCount = 12;//you can initialize with any desired value

    float newValue = 0;
    Scanner scanner = new Scanner( System.in );     

    do{
        System.out.println("Enter your new value. Enter 0 or negative to exit.");
        newValue = scanner.nextFloat();
        if(newValue>0){
            currentScore = (currentScore*currentCount+newValue)/(++currentCount);
            System.out.println("Your new score is "+currentScore);
        }else{
            System.out.println("Program is exiting");
        }

    }while(newValue >0);
   }
  }

如何为这个等式编写一个java程序
