Apr 06, 2018 · The "BufferedWriter" class of java supports writing a chain of characters output stream (Text based) in an efficient way. The Chain-Of-Characters can be Arrays, Strings etc. The "BufferedReader" class is used to read stream of text from a character based input stream.
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. The default is large enough for most purposes. java.io.BufferedWriter class extends the java.io.Writer class. BufferedWriter class is used to write to the stream from buffer. Generally, to increase the efficiency of writing to the output stream this class is used. Java BufferedWriter Examples: Write Strings to Text File Use the BufferedWriter type to create a text file and write strings to it. Call the write and newLine methods. Output – Read & write UTF file (BufferReader & BufferWriter) 1. Start writting contents to file - BufferedWriter(NIO) 2. Successfully written contents to file - BufferedWriter(NIO) 3. Java.io.BufferedReader Class in Java Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. The buffer size may be specified, or the default size may be used. Java BufferedWriter write (int c) Example Below is a java code demonstrates the use of write (int c) method of BufferedWriter class. The example presented might be simple however it shows the behaviour of the write (int c) method. Don’t get confused on the characters being written on the file because it is not straight forward.
Java BufferedReader class is used to read the text from a character-based input stream. It can be used to read data line by line by readLine () method. It makes the performance fast. It inherits Reader class.
