The FileReader class in Java is utilized for reading character files. It extends from the InputStreamReader class, offering a convenient method for retrieving the content of text files.<\/p>\n

The main role of the FileReader class is to read the content of a character file and convert it into a character stream. It can read each character or line of characters in a character file and store them in a buffer for reading. With the FileReader class, we can access data from text files, such as strings and characters.<\/p>\n

Some commonly used methods of the FileReader class include:<\/p>\n

    \n
  1. The read() method reads the next character of a character file and returns its Unicode value.<\/li>\n
  2. The method read(char[] cbuf) reads the contents of a character file into a character array.<\/li>\n
  3. The method read(char[] cbuf, int offset, int length) reads the content of a character file into the specified position of a character array.<\/li>\n
  4. The readLine() method reads the next line of a character file and returns a string.<\/li>\n
  5. close() method: closes the file reader.<\/li>\n<\/ol>\n

    It is important to note that the FileReader class is intended for character-based input and is suitable for reading text files, not binary files. For reading binary files, one should use the InputStream or FileInputStream class.<\/p>\n","protected":false},"excerpt":{"rendered":"
