What is Bufferreader and BufferedWriter in Java?
BufferedReader bufferedReader = new BufferedReader(reader); will buffer the input from the specified file.

What is a buffered Writer in Java?
BufferedWriter is a sub class of java. io. Writer class. BufferedWriter writes text to character output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. The buffer size may be specified, or the default size may be used.
What is a buffer in Java?
Buffers are defined inside java. It is the block of memory into which we can write data, which we can later be read again. The memory block is wrapped with a NIO buffer object, which provides easier methods to work with the memory block.
