如何在java中读取文本文件并存储到数组中

File file = new File("file.txt");

FileReader fileReader = new FileReader(file);

BufferedReader bufferedReader = new BufferedReader(fileReader);

ArrayList<String> arrayList = new ArrayList<>();

String line;
while ((line = bufferedReader.readLine()) != null) {
    arrayList.add(line);
}

bufferedReader.close();

String[] array = arrayList.toArray(new String[arrayList.size()]);

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

public class ReadTextFileToArray {
    public static void main(String[] args) {
        try {
            File file = new File("file.txt");
            FileReader fileReader = new FileReader(file);
            BufferedReader bufferedReader = new BufferedReader(fileReader);

            ArrayList<String> arrayList = new ArrayList<>();
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                arrayList.add(line);
            }

            bufferedReader.close();

            String[] array = arrayList.toArray(new String[arrayList.size()]);

            // 输出数组内容，供参考
            for (String item : array) {
                System.out.println(item);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
