Question

Please write in JAVA code:

Create a simple dice game that rolls 2 die at the press of a button. Append the results of each roll to a text area. If the values rolled are the same(i.e., you've rolled a double), indicate that next to the dice values.

import java.util.Random; 

public class gam{
    // Open file in append mode.
        public static void appendStrToFile(String fileName, 
                                       String str)

            BufferedWriter out = new BufferedWriter(

            out.write(str+"\n"); 
            out.close(); 
        } 
        catch (IOException e) { 
            System.out.println("exception occoured" + e); 
        } 
    } 
    // perform game using random numbers.
         static void func(){

                String s="", d1="",d2="";
                Random rand = new Random();
                int rand_int1 = rand.nextInt(6)+1; 
        int rand_int2 = rand.nextInt(6)+1;
        d1=Integer.toString(rand_int1);
        d2=Integer.toString(rand_int2); 
        if(rand_int1==rand_int2){
                s=d1+", "+d2+" you've rolled a double.";
        }
        else{
                s=d1+", "+d2;
        }

        appendStrToFile("result.txt", s);
                
        }
         public static void main(String []args){
                // crate a file
                File file = new File("C:\\Users\\LENOVO\\Desktop\\game\\result.txt");
                int t=1;
                boolean result;
                try   
                {  
                        result = file.createNewFile();  //creates a new file  
                        if(result)      // test if successfully created a new file  
                        {  
                        System.out.println("file created "+file.getCanonicalPath()); //returns the path string  
                        }  
                        else  
                        {  
                        System.out.println("File already exist at location: "+file.getCanonicalPath());  
                        }  
                }   
                catch (IOException e)   
                        {  
                        e.printStackTrace();    //prints exception if any  
                        } 
                // Take input        
                Scanner myObj = new Scanner(System.in);
                while(t ==1){
                        System.out.println("Press 1 to role dice or press 0 to exit game.");
                        String option = myObj.nextLine();
                        t=Integer.parseInt(option); 
                        if(t==1){
                         func();// perform the game
                        }
                        else{
                                System.out.println("Exiting game...");
                        }

                }

                

        
     }
}

The final results of the game are written to "result.txt" file.
