Answer 1

public class MyClass {
    public static void main(String args[]) {
        int m[][] = {     
                        {1, 0, 2},  
                        {3, 5, 6},  
                        {7, 4, 1}  
                    };  
            
        int rows = m.length;  
        int cols = m[0].length;  
          
        int odd = 0, even = 0;  
        
        for (int i = 0; i < rows; i++){  
            for (int j = 0; j < cols; j++){  
                if(m[i][j] % 2 == 0)  
                    even++;  
                else  
                    odd++;  
            }  
        }  
          
        System.out.println("The frequency of odd numbers = " + odd);  
        System.out.println("The frequency of even numbers = " + even);  
    }
}




/*
run:
  
The frequency of odd numbers = 5
The frequency of even numbers = 4
  
*/
