We will use afunctionto calculate the perimeter of the rectangle. The logic and formula for calculating the perimeter of the rectangle are the same. We will use a function to reuse code later by simply changing the value. Steps for Implementation We create a function to calculate the perimeter...
那个类也有相关的方法,比如findArea或者findPerimeter。shape类有子类,更具体。正方形是一个shape对象,其值shapeType等于square,numberOfSides等于4。它的findArea方法获取lengthOfSides值并求平方。同时,triangle对象对于name、shapeType、numberOfSides有不同的值,其findArea方法也不同。这个例子在快速介绍对象的同时,也...
