从txt文件中读取字符串，并将其存储到java中的char数组中

import java.io.File;
import java.io.FileReader;
import java.io.IOException;

public class ReadFileToStringArray {
    public static void main(String[] args) {
        File file = new File("file.txt"); // 替换为你的txt文件路径

        try (FileReader reader = new FileReader(file)) {
            StringBuilder stringBuilder = new StringBuilder();
            int character;

            while ((character = reader.read()) != -1) {
                stringBuilder.append((char) character);
            }

            String content = stringBuilder.toString();
            char[] charArray = content.toCharArray();

            // 打印char数组
            for (char c : charArray) {
                System.out.print(c);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
