Java FileReader Class getEncoding() Method with Examples
Last Updated :
02 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.
Java
import java.io.FileReader;
import java.nio.charset.Charset;
class GFG {
public static void main(String[] args)
{
try {
FileReader input1 = new FileReader(
"C:\\Users\\lenovo\\Desktop\\input.txt" );
FileReader input2 = new FileReader(
"C:\\Users\\lenovo\\Desktop\\input.txt" ,
Charset.forName( "UTF8" ));
System.out.println(
"Character encoding of input1: "
+ input1.getEncoding());
System.out.println(
"Character encoding of input2: "
+ input2.getEncoding());
input1.close();
input2.close();
}
catch (Exception e) {
e.getStackTrace();
}
}
}

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.
