Java FileReader Class getEncoding() Method with Examples

Last Updated : 2 Feb, 2022

The getEncoding() method of FileReader Class in Java is used to return the name of the current stream's character encoding. If the stream is utilizing a historical encoding name, it will be returned; otherwise, the canonical encoding name of the stream will be returned.

Syntax:

public String getEncoding()

Returns: This method returns the encoding's historical name, or null if the stream has been closed.

Example: We generated two file readers, input1 and input2, in the preceding example. The character encoding is not specified in input1. As a result, the default character encoding is returned by the getEncoding() function. The character encoding, UTF8, is specified by input2. As a result, the getEncoding() function returns the character encoding supplied.

Assume we have a text file named input.txt that contains the following information. This file will be utilized as a source of data in our example application.
