Thread: 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");
		}
	}
}

do i need to put them together in a string and not in a int?

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.

Do you know how to get a String to print in reverse order? http://www.javaprogrammingforums.com...-problems.html

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.
