Buffered input/output

The buffered approach to input/output, commonly referred to as buffered input/output, can be implemented to reduce the number of input/output operations required. This approach is accomplished using temporary storage, known as a buffer. Buffers temporarily hold data during the transfer process. The goal of this approach is to minimize direct interactions with hardware and data streams. Java delivers on this promise by accumulating data in a buffer before processing it.

Now that you have a foundational understanding of buffered input/output, let’s examine the advantages and best practices of using this technique to improve Java application performance.
