Why BufferedReader is faster than FileReader?

BufferedReader#readLine() method is called, characters of a line stored in the buffer, are returned as a String. It saves lots of time and hence is faster than FileReader#read() method.

What is FileReader in Java?

Java FileReader class is used to read data from the file. It returns data in byte format like FileInputStream class. It is character-oriented class which is used for file handling in java.

What is the difference between FileReader and FileInputStream?

1) The first difference is in their type hierarchy, FileReader extends from Reader class while FileInputStream is descendent of InputStream class. 2) The second difference is in their purpose. The FileReader is meant for reading text data while FileInputStream is for reading binary data.

What is the difference between InputStreamReader and BufferedReader?

BufferedReader reads a couple of characters from the Input Stream and stores them in a buffer. InputStreamReader reads only one character from the input stream and the remaining characters still remain in the streams hence There is no buffer in this case. ... will buffer the input from the specified file.

Why BufferedReader is used in Java?

BufferedReader is a Java class that reads text from the input stream. It buffers the characters so that it can get the efficient reading of characters, arrays, etc. It inherits the reader class and makes the code efficient since we can read the data line-by-line with the readline() method.

What is BufferReader class in Java?

The BufferedReader class of Java is used to read the stream of characters from the specified source (character-input stream). ... This class provides a method named read() and readLine() which reads and returns the character and next line from the source (respectively) and returns them.

What is readLine () in Java?

The readLine() method of Console class in Java is used to read a single line of text from the console. ... Return value: This method returns the string containing the line that is read from the console. It returns null if the stream has ended.

What is a FileReader?

The FileReader object lets web applications asynchronously read the contents of files (or raw data buffers) stored on the user's computer, using File or Blob objects to specify the file or data to read. It cannot be used to read a file by pathname from the user's file system. ...

How does InputStreamReader work in Java?

An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset . The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

What is the difference between FileInputStream and BufferedInputStream?

FileInputStream is meant for reading streams of raw bytes such as image data. For reading streams of characters, consider using FileReader. ... A BufferedInputStream adds functionality to another input stream-namely, the ability to buffer the input and to support the mark and reset methods.

What is Java InputStream file?

Java FileInputStream class obtains input bytes from a file. It is used for reading byte-oriented data (streams of raw bytes) such as image data, audio, video etc. You can also read character-stream data.

What is the difference between DataInputStream and InputStream?

An inputStream is the base class to read bytes from a stream (network or file). ... DataInputStream is a kind of InputStream to read data directly as primitive data types. BufferedInputStream is a kind of inputStream that reads data from a stream and uses a buffer to optimize speed access to data.
