Thread: Method for Cedit card check, help!!!!1

What exactly do you need help with (what have you done)?

Im stuck on how to create methods for the sumofodd/even places method. What i have is below....

import javax.swing.JOptionPane;
import java.util.Scanner;
 
public class CreditCard{
public static void main(String [] args){
 
Scanner input = new Scanner(System.in);
 
System.out.println("Enter your credit card number: ");
long number = input.nextLong();
 
System.out.println("Your credit card number is: " + number);
 
if (isValid(number)){
	System.out.println("The credit card number\n " + number + " is a valid");
}
else
	System.out.println("The credit card is not valid");		
}
public static boolean isValid(long number){
	long sumOdd = sumOddPlaces (number);
	long sumEven = sumEvenPlaces (number);
 
	if(sumOdd + sumEven % 10 == 0){
		return true;
	}
	else{
		return false;
}
}
 
public static int getDigit(int number){
	if(number < 10)
		return number;
 
	else{
	int d2 = number % 10;
	int d1 = number / 10;
 
	return d2 + d1;
	}
 
public static int sumOfEvenPlaces(long number){
   String str_prime = (new Integer(number)).toString();
   int lastIndex = str_prime.length()-1;
   	for (i =0; i <= lastIndex - 2; i--){
			if(   ) 
 
 
}
 
 
public static in sumOfOddPlaces(long number){

Here are the two methods i need names i need to make......

// Get the result from Step 2
 
      public static int sumOfEvenPlace(long number)
 
 // Return the sum of the odd place digits in number
 
      public static int sumOfOddPlace(long number)

Here's one way to see if a number is even or odd.

if (n % 2 == 0)
  // n is even
else
  // in is odd
