java find the digit which can sum of a number code example

Example 1: Java program to find the sum of all the digits in the inputted number

long number, sum;
Scanner sc = new Scanner(System.in);
System.out.println("Enter any DIGIT number: ");
number = sc.nextLong();
sc.close();
// For Logic for adding all digits in the given number
for (sum = 0; number != 0; number /= 10) {
	sum += number % 10;
	}
System.out.println("ForLoop Sum of ALL digits: " + sum);

Example 2: to get sum of even digits java

//To find the sum of even digits in a given Number

    public static int getEvenDigitSum(int number){
        if(number<0){
            return -1;
        }
        int finalNumber=0;
        while(number>0){
           if((number%10)%2==0){
               finalNumber+=number%10;

           }
           number=number/10; //takes out last digit to test the next digit


        }
        return finalNumber;
    }
//Output: ex:number=12323 -- Ans: 4
