Tugas 2 PBO B

Kuliah minggu ke-3 PBO hari ini, kelas saya mendapatkan tugas untuk membuat class bangun 3D dengan method, luas permukaan dan volume bangun.

Berikut adalah source code nya:

Main

 /**  
  * Menghitung Keliling dan Luas Lingkaran.  
  *  
  * @author (Ahmad Syauqi)  
  * @version (0.1)  
  */  
 public class MyMain  
 {  
   public static void main(String args[])  
   {  
     Cube aCube;  
     Bar bBar;  
     Tube cTube;  
     Ball dBall;  
     aCube = new Cube();  
     bBar = new Bar();  
     cTube = new Tube();  
     dBall = new Ball();  
     aCube.l = 10;  
     bBar.l = 1;  
     bBar.w = 2;  
     bBar.h = 3;  
     cTube.r = 7;  
     cTube.h = 10;  
     dBall.r = 14;  
     double areaCube = aCube.area();  
     double volumeCube = aCube.volume();  
     double areaBar = bBar.area();  
     double volumeBar = bBar.volume();  
     double areaTube = cTube.area();  
     double volumeTube = cTube.volume();  
     double areaBall = dBall.area();  
     double volumeBall = dBall.volume();  
     System.out.println("Kubus");  
     System.out.println("Panjang Sisi = "+aCube.l);  
     System.out.println("Luas Permukaan = "+areaCube);  
     System.out.println("Volume = "+volumeCube);  
     System.out.println("\nBalok");  
     System.out.println("Panjang Sisi = "+bBar.l);  
     System.out.println("Lebar Sisi = "+bBar.w);  
     System.out.println("Tinggi Sisi = "+bBar.h);  
     System.out.println("Luas Permukaan = "+areaBar);  
     System.out.println("Volume = "+volumeBar);  
     System.out.println("\nTabung");  
     System.out.println("Jari-jari = "+cTube.r);  
     System.out.println("Tinggi = "+cTube.h);  
     System.out.println("Luas Permukaan = "+areaTube);  
     System.out.println("Volume = "+volumeTube);  
     System.out.println("\nBola");  
     System.out.println("Jari-jari = "+dBall.r);  
     System.out.println("Luas Permukaan = "+areaBall);  
     System.out.println("Volume = "+volumeBall);  
   }  
 }  

Kubus

 public class Cube {  
   public double l;  
   public double area(){  
     return 6*l*l;  
   }  
   public double volume() {  
     return l*l*l;  
   }  
 }  

Balok

 public class Bar {  
   public double l;  
   public double w;  
   public double h;  
   public double area(){  
     return (2*l*w)+(2*l*h)+(2*w*h);  
   }  
   public double volume() {  
     return l*w*h;  
   }  
 }  

Tabung

 public class Tube {  
   public double r;  
   public double h;  
   public double area(){  
     return 2*3.14*r*(r+h);  
   }  
   public double volume() {  
     return 3.14*r*r*h;  
   }  
 }  

Bola

 public class Ball {  
   public double r;  
   public double area(){  
     return 4*3.14*r*r;  
   }  
   public double volume() {  
     return 4*3.14*r*r*r/3;  
   }  
 }  

Berikut hasil Screeshot program:
