When you use BufferedWriter to write, the data gets written to an internal buffer.
Only once the internal buffer is full OR if there is a need to flush, this data gets written to the target character stream/writer.
This buffering approach reduces the (costly) interactions with writing to the network or the disk thereby improving the performance compared to using non buffered writers.
The idea behind Big-O notation is to describe how many operations a process takes depending on the size of the problem. In doing this, we are able to communicate the relative complexity of the code algorithm
In this article, we will discuss the need for benchmarking and illustrate the concepts and usage of Java Microbenchmark Harness (JMH) with examples.
