всем привет,подскажите как решить задачу

import java.util.Arrays;

class Solution {
    public static void main(String[] args) {
        int[][] table = new int[][]{
                {1, 2, 3, 4, 5},
                {1, 2, 3, 4, 5},
                {1, 2, 3, 4, 5},
                {1, 2, 3, 4, 5},
                {1, 2, 3, 4, 5}
        };
        printTable(table);
        System.out.println();
        tmpColumn(table,2,4);
        printTable(table);
    }

    public static void tmpColumn(int[][] table, int column1, int column2) {
        for (int y = 0; y < table.length; y++) {
            int x = table[y][column1];
            table[y][column1] = table[y][column2];
            table[y][column2] = x;
        }
    }

    public static void printTable(int[][] table) {
        for (int y = 0; y < table.length; y++) {
            System.out.println(Arrays.toString(table[y]));
        }
    }
}
