JAVA Program than read an integer and calculate the sum of its digits and write the number of each digit of the sum in English

import java.util.*;
public class Main 
{
	public static void main(String[] args) 
	{
        int m, n, sum = 0;
        Scanner sc=new Scanner(System.in);

        m = sc.nextInt();
        while(m > 0)
        {
            n = m % 10;
            sum = sum + n;
            m = m / 10;
        }
        
        System.out.println("Sum of Digits:"+sum);
        
        int v,a,r=0;
        
        String[] number = {"zero","one","two","three","four","five","six","seven","eight","nine"};
      
      while(sum!=0)
      {
             a=sum%10;
             r=r*10+a;
            sum=sum/10;
      }
      
      System.out.print("In Inglish : ");
      
      while(r!=0)
      {
            v=r%10;

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
