javabean实现求矩形的周长和面积

矩形的宽：cm

b.jsp

2、页面<%@pagelanguage="java"import="java.util.*"pageEncoding="gbk"%><%@pageimport="tom.jiafei.Rectangular"%>你给出矩形的长是：cm
你给出矩形的宽是：

3、tyname="squareness"property="width"/>cm
周长是：cm
面积是：cm2Rectangular.java页面packagetom.jiafei;publicclassRectangular{doublelength,width,perimeter,

4、area;publicvoidsetLength(doublea){length=a;}publicdoublegetLength(){returnlength;}publicvoidsetWidth(doubleb){width=b;}publicdoublegetWidth(){returnwidth;}publicdoublegetPerimeter(){//求矩形的周长perimeter=2.0*(length+width);returnperimeter;}publicdoublegetArea(){//求矩形的面积a

5、rea=length*width;returnarea;}}
