JAVA,写一个名为Rectangle的类表示矩形，怎么写？

Answer 1

说明
1。颜色题目没初始化，我定义为“black”
2。 测试函数具体没说测试什么，以及长宽没初始化数值，故代码中只调用toString()方法，具体自己改写

public class Test
{
public static void main(String[] args)
{
Rectangle r1 = new Rectangle(2.3,5.2);
System.out.println(r1.toString());

}

}

class Rectangle
{
private double width,height;
private String color = "black";
Rectangle(double width,double height)
{
this.width = width;
this.height = height;
}
public void setWidth(double width)
{
this.width = width;
}
public double getWidth()
{
return width;
}
public void setHeight(double height)
{
this.height = height;
}
public double Height()
{
return height;
}
public double getArea()
{
return height * width;
}
public String toString()
{
return "长方形的宽是" + width + "长方形的高是" + height + "长方形的颜色是" + color;
}

}
