创建一个桌子Table 类,该类中有桌子名称、重量、桌面宽度、长度
及桌子高度属性。其中有:
a.构造函数初始化所有数据成员
b.Area() :计算桌面的面积
c.Display(): 在屏幕上输出所有数据成员的值
d.ChangeWeight(int ):改变桌子重量的函数
e.在main()中实现创建一个桌子对象,计算桌面的面积,改变桌子重量,
并在屏幕上输出所有桌子数据成员的值。
public class Table{
private String tableName;
private float tableWeight;
private float tableLength;
private float tableWidth;
private float tableHeigth;
public Table(String name,float weight,float length,float width,float heigth)
{
tableName=name;
tableWeight=weight;
tableLength=length;
tableWidth=width;
tableHeigth=heigth;
}
public void area()
{
System.out.println("the area is:"+tableLength*tableWidth);
}
public void display()
{
System.out.println("Name:"+tableName+",Weight:"+tableWeight+",Length:"+tableLength+",Width:"+tableWidth+
",Height:"+tableHeigth);
}
public void changeWeight(int w)
{
tableWeight=w;
}
}class Test{
public static void main(String [] args){
Table tb=new Table("haha",20f,10f,10f,1.5f);
tb.area();
System.out.println("the value of table is:");
tb.display();
tb.changeWeight(666);
System.out.println("!now the value of table is:");
tb.display();
}
}
