I want to read a text file (containing characters) and store them in an array (preferably String or char array) in java.

I have the following file:

I'm using the following code, but it doesn't work:

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: Please ignore the imports & code errors. This is only partial code.

Any help will be much appreciated!

expected output: in a 2-D array

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

The function split() returns array of String , not String . Try the following code:

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

Answer 2

Man do you really need to use an array? I would do something like this to read the file

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();
