方法是您在 Java 程序中调用的代码单元。方法可以支持参数并且通常返回一个值。要在 Java 中创建方法,请遵循以下四个步骤。 1.打开您的文本编辑器并创建一个新文件。键入以下 Java 语句: 您编写的方法名为computeAreaOfRectangle. 它接受两个整数参数并返回一个整数,即两个参数的乘积。 2.将文件另存为CreateAMet...

Each rectangle is defined by its bottom left corner and top right corner as shown in the figure. Assume that the total area is never beyond the maximum possible value of int. 解题思路: 几何题目。 代码如下: 1 2 3 4 5 6 7 8

"area=”+rectangle.area(5,4) 样的话你看这个就不难了，area在双引号里就是说它是要显示出来的，这个加号的意思是说这里有两项内容要显示，要是显示三项的话再来一个加号就是了，依次类推……Static int perimeter(int length,int width) ｛｝这里是对这个方法的定义它有两个变量一个是...
