    Default Can i get some help with an array code

    im new to java and i have trouble with array not sure if i need to make a new static class i believe i do but my code works exactly as i want it to but im missing 2 things a counter counting the number of times my "numholder" variable comes up and as which number ie: 2 came up 3 times till the user hits quit
    not sure if i should put it in an array or write in a counter because it has to count both the straight line and if the user chooses to "bet" on another number without spinning i put in the option alrdy under my "additional" variable but i think thats were i need my array not sure if theres another way to do it would appreciate some help

    if (bet == 'a'|| bet == 's')
     
    										{
     
    											if (bet == 'a')
    											{ 
     
    												System.out.println("If you bet a number leave a space between each number");
    												s=scan2.toString();
    												String arrayString[] = s.split("\\s+"); 
     
     
    												String[] items = s.split("\\s+");
     
    												int[] results = new int[items.length];
     
    												for (int i = 0; i < items.length; i++) 
    												{
     
    												    try {
    												        results[i] = Integer.parseInt(items[i]);
    												    } catch (NumberFormatException nfe) {};
     
     
    											amountholder= howmuch* arrayString.length;
    												}			
    														if (amountholder>iamount)
    															{ 
    																System.out.println("You bet to much");	
    															}	
     
    															else {
    															int numholder1 = rand.nextInt(odds) + 1;		
    															int[] array = results;
    																	int value =numholder;
     
    																	int index = Arrays.asList(array,betnum).indexOf(numholder);
    																	System.out.println("You got" + numholder1);
    																	if(index>0);
    																	{      
    																		wins++;
     
    																		newcash=iamount +(howmuch* (odds-1));
     
    																		System.out.println("Congratz you Won" + " "+ (howmuch* (odds-1)));
    																	}                                      
     
    																	if(index<0) 
    																	             {
    																		newcash= (iamount-howmuch);
    																		lose++;
    																		System.out.println("Sorry you lost" +" " + howmuch);
     
    																	              }                
    																	}
     
    										System.out.println("You now have "+ newcash + "$");
     
    										System.out.println("Type: b to bet");
    										System.out.println("Type q to quit");
    										userinput = scan1.nextLine().charAt(0);

    Thanks for posting your code correctly, but your problem statement/question is very hard to read and understand. Can you add some punctuation, maybe ask an actual question so that we know what you need help with? Showing actual output versus desired might be helpful.

    do you need to throw each extra bet into an array or can you use some type of if statement?
    The bets need to be stored somewhere and that somewhere could be an array.
    i need the counter to say 2 came up 3times or however many times your spinned till u quit
    Similarly, multiple results that correspond to multiple bets need to be stored somewhere. Parallel arrays, one for bets and the other for results, are not my favorite solution, but I suspect that it's appropriate for your level.

    To pursue the parallel array approach, you'll need to decide the maximum number of bets that can be placed to size the arrays, OR use a collection that can vary in size, like an ArrayList.

    You'll suck less if you practice using them and gain confidence through experience. Someone showing you examples won't help your confidence or gain you experience.
