Answer with Explanation

Here is the Java program to sort each row of a 2D array in ascending order:


import java.util.Arrays;

public class RowWiseSorting {
    public static void main(String[] args) {
        int[][] array = {
            {9, 7, 5},
            {3, 1, 2},
            {6, 4, 8}
        };

        System.out.println("Original 2D Array:");
        print2DArray(array);

        // Sorting each row of the 2D array
        for (int i = 0; i < array.length; i++) {
            Arrays.sort(array[i]); // Sorts each row in ascending order
        }

        System.out.println("\n2D Array After Row-wise Sorting:");
        print2DArray(array);
    }

    // Method to print a 2D array
    public static void print2DArray(int[][] array) {
        for (int[] row : array) {
            System.out.println(Arrays.toString(row));
        }
    }
}

Output: 


Original 2D Array:  
[9, 7, 5]  
[3, 1, 2]  
[6, 4, 8]  

2D Array After Row-wise Sorting:  
[5, 7, 9]  
[1, 2, 3]  
[4, 6, 8]
