Apr 09, 2019 · I doubt that the statement “try (BufferedReader br = new BufferedReader(new FileReader(FILENAME)))” will not close both BufferedReader and FileReader. To close both the readers, we need to use “try(FileReader fr = new FileReader(FILENAME); BufferedReader br = new BufferedReader(fr))”. Please check.
BufferedReader 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. The default is large enough for most purposes. Apr 06, 2018 · Using the "readLine ()" method of the BufferedReader, we are reading all three line of texts (Marked as 3). Note that the readLine () method reads the line of text along with the newline character. So, when we print the readLine () return string in the console output window, the cursor goes to next line after printing the line. how about you create a method inside FileReadExample class which uses the in.readLine() method and returns a String value. So eg. if you create a method called String readALine() which returns str. you can use it in your testMain class like this-> mystr = fr.readALine(); – Onkar Borgaonkar Apr 28 '13 at 18:10 Java.io.BufferedWriter class methods in Java Bufferreader class writes text to character-output stream, buffering characters.Thus, providing efficient writing of single array, character and strings. A buffer size needs to be specified, if not it takes Default value. Jun 25, 2020 · The most useful package that is provided for this is the java.io.Reader.This class contains the Class BufferedReader under package java.io.BufferedReader What is BufferedReader in Java?

BufferedReader Basics The BufferedReader class main functionality is to reads text from inputstream. Morever it is used to buffer characters for the purpose of efficient handling of characters, arrays and strings.
BufferedReader in = new BufferedReader(new FileReader("foo.in")); will buffer the input from the specified file. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient.
