逻辑错误Java - BMI中的错误计算

public class BMICalculator {
    public static double calculateBMI(double weight, double height) {
        if (weight <= 0 || height <= 0) {
            throw new IllegalArgumentException("Weight and height must be positive numbers.");
        }
        
        double heightInMeter = height / 100; // 将身高从厘米转换为米
        double bmi = weight / (heightInMeter * heightInMeter);
        return bmi;
    }
    
    public static void main(String[] args) {
        double weight = 70; // 体重（kg）
        double height = 170; // 身高（cm）
        
        try {
            double bmi = calculateBMI(weight, height);
            System.out.println("BMI: " + bmi);
        } catch (IllegalArgumentException e) {
            System.out.println("Error: " + e.getMessage());
        }
    }
