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 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.
