What is the FileWriter class in Java? | Java IO | Java Tutorial

In Java IO, the `FileWriter` class is used to write character data to a file. It is a subclass of the `Writer` class and provides methods to write data to a file as characters. Here's a detailed description of the `FileWriter` class:

The `FileWriter` class in Java provides a convenient way to write character data to a file. It is a subclass of the abstract `Writer` class and is used specifically for writing character streams.

When you create an instance of the `FileWriter` class, you specify the file you want to write to. If the file does not exist, a new file will be created. If the file already exists, its contents will be overwritten by default, unless you specify otherwise.

You can use various methods provided by the `FileWriter` class to write data to the file. These methods include `write(char[] cbuf)`, `write(String str)`, `write(int c)`, and `flush()`, among others.

It's important to properly handle exceptions when working with FileWriter, as IO operations can potentially throw IOException. This ensures that your program behaves predictably even in the presence of errors.

Overall, the `FileWriter` class is a useful tool for writing character data to files in Java, and understanding its usage can be beneficial for file handling operations in Java applications.
