0. 缓存机制

  • 缓存也可视为一种中间层,只是从缓存的角度,带来的不是底层细节的屏蔽,而是效率的提升;

1. 流式读取

  • 比如网络 io(net io)

    URL url = new URL("http://www.baidu.com");
    
    InputStream inStream = url.openStream();
    byte[] buffer = new byte[1024];
    ByteArrayOutputStream outStream = new ByteArrayOutputStream();
    int len = -1;
    while ((len = inStream.read(buffer)) != -1)
    {
        outStream.write(buffer, 0, len);
    }
