Question

这是下面的代码

        public static double rectangleArea(double length, double width)
        {
           Area = length*width;
            System.out.println("Area: " + area);
            return area;

Answer 1

根据你的代码，我假设你是用 Java 编写的。假设这可行:

public class Logic { 
    public static double rectangleArea(double length, double width) {
      double area = length*width; 
      System.out.println("Area: " + area); 
      return area;
    }
}
