Java Program to find the frequency of odd & even numbers in the given matrix
public class OddEven
{
public static void main(String[] args) {
int rows, cols, countOdd = 0, countEven = 0;
//Initialize matrix a
int a[][] = {
{4, 1, 3},
{3, 5, 7},
{8, 2, 6}
};
//Calculates number of rows and columns present in given matrix
rows = a.length;
cols = a[0].length;
//Counts the number of even elements and odd elements
for(int i = 0; i < rows; i++){
for(int j = 0; j < cols; j++){
if(a[i][j] % 2 == 0)
countEven++;
else
countOdd++;
}
}
System.out.println("Frequency of odd numbers: " + countOdd);
System.out.println("Frequency of even numbers: " + countEven);
}
}
Output:
Frequency of odd numbers: 5
Frequency of even numbers: 4
