代码如下

class Box{

private int width;

private int length;

private int height;

public Box(int width,int length,int height){

this.width = width;

this.length = length;

this.height = height;

}

public void showBox(){

System.out.println("盒子的width、length、height分别为"+width+","+length+","+height);

}

}

这很简单啊，看图：

望采纳！

追问public class Box{
private double width;
private double length;
private double height;
public Box(double width, double length, double height){
this.width = width;
this.length = length;
this.height = height;
}
public void showBox(){
System.out.printf("width=%f; length=%f; height=%f", width, length, height);
}
}

这个是对的吗

class box
{
double length,width,height;

public box(double length,double width,double height){
this.length = length;
this.width = width;
this.height = height;
}

public void setlength(double x){
length = x;
}
public void setwidth(double x){
width = x;
}
public void setheight(double x){
height = x;
}

public double getlength(){
return length;
}
public double getwidth(){
return width;
}
public double getheight(){
return height;
}

public double getarea(){
return (lenght*width+length*height+width*length)*2;
}

public double getvolumn(){
return length*height*width;
}
}

public class testbox
{
public static void main(string [] args){
box b = new box(2,4,5);

}
}
