如题

Answer 1

public class Test {
	public static double area(double length,double width){
		return length * width;
	}
	public static double bulk(double length,double width,double height){
		return length * width * height;
	}
	public static void main(String[] args) {
		System.out.println("面积："+Test.area(12.5, 2));
		System.out.println("体积："+Test.bulk(12.5, 2, 2.5));
	}
}
