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
// Java Program to demonstrate the working of // getEncoding() Method of FileReader Class import java.io.FileReader; import java.nio.charset.Charset; class GFG { public static void main(String[] args) { try { // Creates a FileReader with the encoding set to // default. FileReader input1 = new FileReader( "C:\\Users\\lenovo\\Desktop\\input.txt" ); // Creates a FileReader with the specified // encoding. FileReader input2 = new FileReader( "C:\\Users\\lenovo\\Desktop\\input.txt" , Charset.forName( "UTF8" )); // The file reader's character encoding is // returned. System.out.println( "Character encoding of input1: " + input1.getEncoding()); System.out.println( "Character encoding of input2: " + input2.getEncoding()); // Closing Reader 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.
