public class PrintSpecificRowOfMatrix_Java {
    public static void PrintSpecificRowOfMatrix(int[][] matrix, int row) {
        int cols = matrix[0].length;
        
        for (int j = 0; j < cols; j++) {
            System.out.print(matrix[row][j] + " ");
        }
    }
 
    public static void main(String[] args) {

            { 29, 4, 7, 9, 18, 6 } };
 
        int row = 2;
 
        PrintSpecificRowOfMatrix(matrix, row);
