Write a Java program to print the area and perimeter of a rectangle. Java: Perimeter of a rectangle A perimeter is a path that surrounds a two-dimensional shape. The word comes from the Greek peri (around) and meter (measure). The perimeter can be used to calculate the length of fence...
.编写一个完整的Java Application 程序。包含接口ShapeArea,MyRecta具体要求如下: ⑴接口ShapeArea: double getArea():求一个形状的面积 double getPerimeter ():求一个形状的周长 ⑵类 MyRectangle:
先回答你的问题 "area"=+rectangle.area(5,4)这是要 打印的内容 应该会打印出“area=20” area加引号说明是字符串 加点说明是周长perimeter和面积area是rectangle类中的方法 就像你说System.out.println一样 println就是system类的一个方法 当然这个方法还比较特殊 需要用out标明是输出再说你这代码 ...
