用java编写,求大神解答,跪谢了! 假设需要制造一个带有四个按钮和两个灯泡的盒子并具有以下功能:

这12个步骤已经详细的列出了做题的思想。 你就跟着思想一步一步来。代码是从上倒下一步一步执行的。 关键字 if 判断

编写一个盒子类Box的Java程序。 将参数传递给构造方法,计算盒子体积 capacity,在控制台输出。

class Box{

private double length;

private double width;

private double height;

public Box() {

if(lenght 0 || width 0 || height 0) {

System.out.println("输入值不合法!");

}

System.out.println("盒子体积是:"+length*height*width);

}

}

用JAVA编写:设计并实现类Box,所包含的实例数据表示盒子的高度、宽度和厚度,一个boolean型实例数据

public class Box {

private double height, width, thickness;

private boolean full;

Box(double height, double width, double thickness){

this.height=height;

this.width=width;

this.thickness=thickness;

full=false;

}

public double getHeight(){

return height;

}

public double getWidth(){

return width;

}

public double thickness(){

return thickness;

}

public boolean getFull(){

return full;

}

public void setHeight(double height){

this.height=height;

}

public void setWidth(double width){

this.width=width;

}

public void setThickness(double thickness){

this.thickness=thickness;

}

public void setFull(boolean full){

this.full=full;

}

public String toString(){

String s="";

if(getFull()==true)

s="The height of the box is "+getHeight()+";"

+"The height of the box is "+getHeight()+";"

+"The height of the box is "+getHeight()+";"

+"and the box is full";

else

s="The height of the box is "+getHeight()+";"

+"The height of the box is "+getHeight()+";"

+"The height of the box is "+getHeight()+";"

+"and the box is not full";

return s;

}

public static void main(String args[]){

Box b1=new Box(12.1,10.3,9.5);

Box b2=new Box(5.3,3.5,2.5);

System.out.println(b1);

System.out.println(b2);

b1.setFull(true);

b1.setHeight(15);

b1.setWidth(13);

b1.setThickness(14);

b2.setHeight(6);

b2.setWidth(4);

b2.setThickness(8);

System.out.println(b1);

System.out.println(b2);

}

}
