错误：类中的方法无法应用于给定类型

Question

如何摆脱此错误？

它说：

required: double, double
found: no arguments
reason: actual and formal argument lists differ in length

代码：

public double computeBMI(double kg, double meter)
{
    double bmin;

    bmin= kg/(meter*meter);

    return bmin;
}

public static void main (String args[])
{
    BMI obj = new BMI();    
    double bmin = obj.computeBMI();  //error appears here the period is highlighted.
    obj.checkStatus(bmin);
}   

Answer 1

嗯，您的const string backToChars = to_string(num + 13.0); copy(backToChars.cbegin(), backToChars.cend(), cstring + 5); 方法需要两个computeBMI。您没有传递任何内容，请尝试在错误行的空括号中输入两个doubles。错误消息告诉您。
