Reading and Writing Text Files

Handling text files in Java involves performing operations like reading from, writing to, and appending to files. Here are some common techniques and examples for handling text files in Java: FileReader and BufferedReader are classes in Java used for reading text from files. Here’s a detailed explanation of each: FileReader FileReader is a class in Java that is used to read character files. It is a convenient class for reading text files using the default character encoding of the operating system. Key Points: Purpose : To read text files. Inheritance : It extends InputStreamReader , which in turn extends Reader . Encoding : Uses the default character encoding of the operating system unless specified otherwise. Basic Usage : Suitable for simple file reading tasks. Example: create a text file "example.txt" using any text editor and then run this program.In this example, FileReader reads the file character by character. import java.io.FileReader; import java.io.IOException; ...
