I want to sort array in ascending order by using this code please help

import java.util.Scanner;

public class matrix {
    public static void main(String[] args) {
        int a, b;
        try (Scanner s = new Scanner(System.in)) {
            System.out.println("Enter total rows: ");
            int row = s.nextInt();
            System.out.println("Enter total columns: ");
            int column = s.nextInt();
            int array[][] = new int[row][column];
            {
                System.out.println("Enter Elements: ");
                for (a = 0; a < row; a++) {
                    for (b = 0; b < column; b++) {

                        array[a][b] = s.nextInt();
                        System.out.print("");

                    }
                }
                System.out.print("");

                System.out.println(" Matrix before Transpose is ");
                for (a = 0; a < row; a++) {
                    for (b = 0; b < column; b++) {
                        System.out.print(" " + array[a][b] + " ");
                    }
                    System.out.println();
                }
                System.out.println("");
                System.out.println("The above matrix after Transpose is ");
                for (a = 0; a < column; a++) {
                    for (b = 0; b < row; b++) {
                        System.out.print(" " + array[b][a] + " ");
                    }
                    System.out.println("");

                }
                System.out.println("");

                int max = Integer.MIN_VALUE;
                for (a = 0; a < row; a++) {
                    for (b = 0; b < column; b++) {
                        if (max < array[a][b]) {
                            max = array[a][b];
                        }
                    }
                }

                System.out.println("Maximum number in the matrix is " + max);
            }
        }
        System.out.println();
        // System.out.println("Matrix in asscending order"+);

    }
