Write a function to print the sum of the even and odd digit with given condition?

Question

Rohit's teacher has asked him to write a function that takes as input parameters the first parameter will be an integer number representing. The number whose digitSum needs to be found the second parameter will be a char representing the
option which would either be 'e' or 'o' representing 'even' or 'odd' respectively.

Function signature public int digitSum(int n, char ch);

digitSum(9625, 'o')
Example 1: if given number is 9625 and the option is 'o' we must add only the odd digit i.e. 9+5=14
digitSum(2134, 'e')
Example 2: if given number is 2134 and the option  is 'e' we must add only the odd digit i.e. 2+4=6

Answer 1

Even OR Odd Digits' Sum: try this code this is very similar, just input parameter is in string

 public EvenOddDigitsSum(int input1, String input2){
    int rem,sum=0;
       while(input1>0){
           rem=input1%10;
           input1/=10;
           if(input2.equals("odd")){
           if(rem%2!=0)   sum+=rem;   
           }
           else if(input2.equals("even")){  
           if(rem%2==0)   sum+=rem;   
           }
      }
    return sum;
}
