Java，如何有效地分块大输入流的片段？

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.IOException;

public class StreamChunkingExample {
    private static final int CHUNK_SIZE = 1024; // 每块数据的大小

    public static void main(String[] args) {
        try (BufferedInputStream inputStream = new BufferedInputStream(new FileInputStream("input.txt"))) {
            byte[] buffer = new byte[CHUNK_SIZE];
            int bytesRead;

            while ((bytesRead = inputStream.read(buffer)) != -1) {
                processChunk(buffer, bytesRead);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static void processChunk(byte[] chunk, int bytesRead) {
        // 在这里对每一块数据进行处理
        // 可以进行解析、分析、转换或存储等操作
        // 示例代码只是简单地打印每块数据的内容
        System.out.println(new String(chunk, 0, bytesRead));
    }
}
