Question

我想读取一个文本文件（包含字符）并将它们存储在java中的数组（最好是String或char数组）中。

我有以下文件：

我正在使用以下代码，但它不起作用：

public class A3 {

    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub

        FileReader f = new FileReader("C:\\Users\\Dell\\Desktop\\COSC600\\sampleinp.txt");
        BufferedReader br = new BufferedReader(f);

        String ar[][] = new String [50][50];

        for(int i=0;i<ar.length;i++) {
            for(int j=0;j<ar.length;j++) {
                String s = br.readLine();
                ar[i][j] = s.split(" ");
            }
        }
    }

}

PS：请忽略进口＆amp;代码错误。这只是部分代码。

非常感谢任何帮助！

预期输出：采用二维数组

T I R Q H H V Z Z R D A P O B .........P
M L W L O P B I E W V O G G O .........V
Y Q S I T H G I E Q O .................A

Answer 1

函数$this->input->post('wktu_up', TRUE);返回split()的数组，而不是String。请尝试以下代码：

String

Answer 2

你真的需要使用数组吗？我会做这样的事情来读取文件

import java.util.ArrayList;
import java.util.List;

 public class A3 {

public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub

    FileReader f = new FileReader("C:\\Users\\Dell\\Desktop\\COSC600\\sampleinp.txt");
    BufferedReader br = new BufferedReader(f);

    List<String[]> words = new ArrayList<String[]>();

    line = br.readLine();
    while(line != null){

    words.add(line.split(""));
    line = br.readLine();   

}}}

阅读文本文件（包含字符）＆amp;将它存储在java中的2D数组中
