# switch stament problem

Posted 10 October 2012 - 06:40 AM

Create a program that simulates a slot machine. When the program runs, it should do the
following:
• Asks the user to enter the amount of money he or she wants to enter into the slot
machine.
• Instead of displaying images, the program will randomly select a word from the
following list: Cherries, Oranges, Plums, Bells, Melons, Bars. To select a word, the
program can generate a random number in the range of 0 through 5. If the number is 0,
the selected word is Cherries; if the number is 1, the selected word is Oranges; and so
forth. The program should randomly select a word from this list three times and display
all three of the words.
• If none of the random selected words match, the program will inform the user that he
or she has won \$0. If two of the words match, the program will inform the user that he
or she has won two times the amount entered. If three of the words match, the
program will inform the user that he or she has won three times the amount entered.
• The program will ask whether the user wants to play again. If so, these steps are
repeated. If not, the program displays the total amount of money entered into the slot
machine and the total amount won.

``` public static void main(String[] args) {
//define var
//String Cherries, Oranges, Plums, Bells, Melons, Bars;
int one,two,three,four,five,num,count;
double bet;
Random rand = new Random();

Scanner keyboard = new Scanner (System.in); //New scanner class

System.out.print("How much would you like to bet? ");//get's user input and bet
bet = keyboard.nextDouble();

for (count=1; count<=3;count++)
{

int picked = rand.nextInt(5);

switch (picked){
case 0:
System.out.print("Bells ");
break;
case 1:
System.out.print("Cherries ");
break;
case 2:
System.out.print("Orange ");
break;
case 3:
System.out.print("Plums ");
break;
case 4:
System.out.print("Melons ");
break;
case 5:
System.out.print("Bars ");
break;

}

}

}
}

```

I was given this task above, this is the code I have. I am stuck at a stand still how can I save the input from the first time the for loop runs to a specific variable? can I use a ++ on a variable i.e
``` word1 = .....
word1++
word2 = ....

```
? Im still stuck any help is appreciated I looked at many examples I can not for the life of me figure it out.

Is This A Good Question/Topic? 0

You'd be better off using an array than switch

Is there anyway to make something like this work?
``` public static void main(String[] args) {
//define var
//String Cherries, Oranges, Plums, Bells, Melons, Bars;
int one,two,three,four,five,num,count;
double bet;
Random rand = new Random();
int word=0,word1=word+1,word2=word+2;

Scanner keyboard = new Scanner (System.in); //New scanner class

System.out.print("How much would you like to bet? ");//get's user input and bet
bet = keyboard.nextDouble();

for (count=1; count<=3;count++)
{

int picked = rand.nextInt(5);

switch (picked){
case 0:
System.out.print("Bells ");word=1;
break;
case 1:
System.out.print("Cherries "); word=1;
break;
case 2:
System.out.print("Orange "); word=1;
break;
case 3:
System.out.print("Plums "); word=1;
break;
case 4:
System.out.print("Melons "); word=1;
break;
case 5:
System.out.print("Bars "); word=1;
break;

}

word++;
}
if(word==word1 || word==word2 || word2 == word1){
System.out.println("you won double money");
}

}
}

```

I wouldn't Using an array is clearer and simpler

Also, your code would be much cleaner if word,word1,word2 were int [] word = new int[3];.

Learn arrays. Honestly, forget switches; you never actually need them. You do need arrays.

Also this statement:
int picked = rand.nextInt(5);

returns a value between 0 and 4 inclusive so never "Bar" will be selected

Thanks for all the help I guess it is time to learn about arrays. These are great forums and I am sure I will be back.
