在Java中使用Stringbuilder读取一个巨大的文本文件并添加

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadLargeTextFile {
    public static void main(String[] args) {
        StringBuilder stringBuilder = new StringBuilder();
        try (BufferedReader reader = new BufferedReader(new FileReader("path/to/large/file.txt"))) {
            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println(stringBuilder.toString());
    }
}
