创建2D数组，然后使用用户输入打印奇数的总数。 和那个数组中的奇数之和

Question

This what I have done so far. I can't get to print the total number of odd numbers in the array and the sum of that odd numbers.

import java.util.Scanner;

public class arrayssumofodd
{
    public static void main(String args[])
    {
        Scanner scan = new Scanner(System.in);

        int rows=scan.nextInt();
        int columns=scan.nextInt();
        int array[][]=new int [rows][columns];

        int odd=0;
        int sum=0;
        int num=0;

        for(int i=0;i<rows;i++)
        {
            for(int j=0; j<columns;j++)
            {
                array[i][j]=scan.nextInt();
                num=array[i][j];

            }

            for(int k=0;k<rows;k++)
            {
                for(int m=0;m<k;m++)
                {
                    if(num%2!=0)
                    {
                        odd++;
                        sum+=odd;
                    }
                }
            }
        }
        System.out.println("Odd number count "+" = " +odd);
        System.out.println("Sum of odd numbers "+" = " +sum);
    }
}

I've tried everything to get the odd numbers to print but I haven't been able to. It keeps outputting zero when I run the program.

Your for loops are mixed with each other.

for(int i=0;i<rows;i++)
{
    for(int j=0; j<columns;j++)
    {
        array[i][j]=scan.nextInt();
        num=array[i][j];
        // you can do operation with odd count and sum here
}

Or you can use the same two for loops to go through the numbers in the 2D array and just count the odd number and find the sum.
