Tugas PBO Remote AC

Hey guys! In this post I'm going to show you how to make an AC Remote using BlueJ.
I'm going to use 2 classes, which are:

1. Main
2. ACRemote

Main

 /*  
  * Main function for the AC Remote  
  *

  */  
 import java.util.Scanner;  
 public class Main{  
   public static void main(String args[]){  
     int menu;  
     Scanner input = new Scanner(System.in);  
       
     //Creates the remote  
     ACRemote remote = new ACRemote();  
     while(true){  
       //displays the remote interface every loop  
       remote.display();  
         
       //scans for menu number  
       menu = input.nextInt();  
       switch(menu){  
         //changes the temperature  
         case 1: remote.TempUp(); break;  
         case 2: remote.TempDown(); break;  
           
         //sets the AC swing mode  
         case 3: remote.getSwing(); break;  
           
         //terminates when the AC turned off  
         case 4: System.exit(0); break;  
       }  
     }  
   }   
 }  

ACRemote

 /*  
  * AC Remote Function  
  *  
  * Elkana Hans Widersen  
  * 05111740000127  
  * 23 September 2018  
  */  
 public class ACRemote{  
   private int temp;  
   private String swing;  
     
   //AC Remote Declaration  
   public ACRemote(){  
     temp = 24;  
     swing = "OFF";  
   }  
     
   //Sets Swing Mode  
   public void getSwing(){   
     if(swing == "OFF") swing = "ON ";   
     else swing = "OFF";   
   }   
     
   //Decrease temperature  
   public void TempDown(){  
     if(temp == 18) temp = 18;  
     else temp--;  
   }  
   
   //Increase temperature  
   public void TempUp(){  
     if(temp == 30) temp = 30;  
     else temp++;  
   }  
     
   //Displays the remote interface  
   public void display(){   
     System.out.println("|-------------------|");   
     System.out.println("|   TOSHIBA   |");   
     System.out.println("| Air Conditioner |");  
     System.out.println("|-------------------|");  
     System.out.println("|     " + temp + "    |");  
     System.out.println("|-------------------|");   
     System.out.println("|  SWING = " + swing + "  |");   
     System.out.println("|-------------------|");   
     System.out.println("| 1. ^  2. v  |");  
     System.out.println("| 3. Swing ON/OFF |");   
     System.out.println("| 4. AC Power OFF |");   
     System.out.println("|-------------------|\n");  
   }  
 }  

When you are done, it should look like this:

Thank you and see you next time!
