Java二维字符数组

Question

我需要编写一个具有数组返回方法的 Java 程序，该方法将二维字符数组作为参数并返回一维字符串数组。这是我的东西

import java.util.Scanner;
public class TwoDimArray {

    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        System.out.println("Enter the number of Rows?");
        int rows = s.nextInt();
        System.out.println("Enter the number of Colums?");
        int cols = s.nextInt();
        int [][] array = new int [rows] [cols];
    }

    public static char[ ] toCharArray(String token) {
        char[ ] NowString = new char[token.length( )];
        for (int i = 0; i < token.length( ); i++) {
            NowString[i] = token.charAt(i);
        }
        return NowString;
    }
}

您需要一个字符串数组，而不是字符数组:

public static String[] ToStringArray(int[][] array) {
    String[] ret = new String[array.length]; 

    for (int i = 0; i < array.length; i++) {
       ret[i] = "";
       for(int j = 0; j < array[i].length; j++) {
          ret[i] += array[i][j];
       }

    }
    return ret;
}
