    Default Loopy Lotto....

    Cant Seem to get my if thens to stop adding each other. I want them to go num1,num2,num3 but this program is adding all 3 together.... Rough...

    import javax.swing.JOptionPane;
     
    public class Lotto {
    	public static void main(String[] args) {
     
    		String inputOneString = JOptionPane.showInputDialog(
    			"Enter the First Digit of Your Lotto Number Pick");
     
    		int inputOne = 
    			Integer.parseInt(inputOneString);
     
    		String inputTwoString = JOptionPane.showInputDialog(
    			"Enter the Second Digit of Your Lotto Number Pick");
     
    		int inputTwo = 
    			Integer.parseInt(inputTwoString);
     
    		String inputThreeString = JOptionPane.showInputDialog(
    			"Enter the Third Digit of Your Lotto Number Pick");
     
    		int inputThree = 
    			Integer.parseInt(inputThreeString);
     
    		int numberOne = (int)(System.currentTimeMillis() % 10);
    		int numberTwo = (int)(System.currentTimeMillis()*4  % 10);
    		int numberThree = (int)(System.currentTimeMillis()*5 % 10);
    		int lottoNumber = numberOne + numberTwo + numberThree;
    		int userNumber = inputOne + inputTwo + inputThree;
     
    		if (userNumber == lottoNumber) {
    			System.out.println("The Lotto Number Was " + lottoNumber + " Your Numbers Match Exactly!! You Win $10,000");
    		}
    		else if (userNumber == (numberOne + numberThree + numberTwo) OR (numberTwo + numberOne + numberThree) OR (numberTwo + numberThree + numberOne) OR (numberThree + numberOne +numberTwo) OR (numberThree + numberThree + numberOne)){
    			System.out.println("The Lotto Number Was " + lottoNumber + " Your Numbers Match All 3 Numbers in a Different Order!! You Win $3,000");
    		}
    		else if ((inputOne == numberOne) OR (inputTwo == numberTwo) OR (inputThree == numberThree)){
    			System.out.println("The Lotto Number Was " + lottoNumber + " Your Numbers Match 1 of the 3 Numbers!! You Win $1,000");
    		}
    		else {
    			System.out.println("The Lotto Number Was " + lottoNumber + " Your Numbers did not Match any of the Lotto Numbers. You Lose");
    		}
    	}

    Well, adding integers together will add them mathematically.

    Yes, make it a String.

    String lottoNumber = numberOne + "," + numberTwo + "," + numberThree;

    String userNumber = inputOne + "," + inputTwo + "," + inputThree;

    if (lottoNumber.equals(userNumber))

    Also, perhaps it'll add it

    else if (userNumber == (numberOne + numberThree + numberTwo) OR (numberTwo + numberOne + numberThree) OR (numberTwo + numberThree + numberOne) OR (numberThree + numberOne +numberTwo) OR (numberThree + numberThree + numberOne)){

    Also, the Or operator is || except with bytes and the And operator is && except with bytes. I don't know much about bytes so I can't answer about those.

    You'll have to replace userNumber == with userNumber.equals(values);

    and values be

    numberOne + "," + numberThree + "," + numberTwo;

    If that still won't work by replacing all of those, you'll have to make those values like shown above as Strings and use the equals method comparing userNumber.equals(thatString)

    else if ((inputOne == numberOne) OR (inputTwo == numberTwo) OR (inputThree == numberThree)){

    inputOne is a String. numberOne is an int. They will never be equal as your code currently is.

    They have to be the same type.

    Using the Integer wrapper class, you could do this;

    Integer n1 = numberOne;

    String n1String = n1.toString();

    inputOne.equals(n1String)


    Hope that helps.

    Using the Integer wrapper class, you could do this;

    Integer n1 = numberOne;

    String n1String = n1.toString();

    inputOne.equals(n1String)
    You don't even need to do that. Just:
    inputOne.equals(numberOne+"");

    You can just add a blank String to any object to automatically call its toString() method. For simple types, they are already represented in the same way as their Wrapper Class's toString() method so it it not necessary to use a Wrapper class.

    I only ever use Wrapper Classes for Lists (ArrayLists, Vectors, ect.) that do not support simple types.

    Do you know how to get a String to print in reverse order? Have a few odd problems.

    Right now I have no clue why it's not storing anything in str for values other than 1 or 2.

    Also, I think even if I had it right, it'll be printing the binary value of the number backwards, unless I can figure out how to switch calling something till the right time.
