This class contains constructors and methods that are given below.

Tika AutoDetectParser Constructors

Constructor	Description
public AutoDetectParser()	It creates an auto-detecting parser instance using the default Tika configuration.
public AutoDetectParser(Detector detector)	It creates an auto-detecting parser instance.
public AutoDetectParser(Parser... parsers)	It creates an auto-detecting parser instance using the specified set of parser.
public AutoDetectParser(Detector detector, Parser... parsers)	It creates an auto-detecting parser instance using the specified detector and parser.
public AutoDetectParser(TikaConfig config)	Creates an auto-detecting parser instance using the specified set tika config.

Tika AutoDetectParser Methods

Following are the methods of Tika AutoDetectParser Class.

Method	Description
public Detector getDetector()	It returns the type detector used by this parser to auto-detect the type of a document.
public void setDetector(Detector detector)	It sets the type detector used by this parser to auto-detect the type of a document.
public void parse(InputStream stream, ContentHandler handler, Metadata metadata, ParseContext context) throws IOException, SAXException, TikaException	It is used to parse the input file.
public void parse(InputStream stream, ContentHandler handler, Metadata metadata) throws IOException, SAXException, TikaException	It calls the Parser.parse(InputStream, ContentHandler, Metadata, ParseContext) method with an empty ParseContext.

Tika AutoDetectParser Example

import java.io.IOException;
import java.io.InputStream;
import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.sax.BodyContentHandler;
import org.xml.sax.SAXException;

// Parsing using Auto-Detect parser
public class AutoDetectParseExample {
	public static void main(String[] args) throws IOException, SAXException, TikaException {
		System.out.println(parseToPlainText());
	}
	public static String parseToPlainText() throws IOException, SAXException, TikaException {
	    BodyContentHandler handler = new BodyContentHandler();
	 
	    AutoDetectParser parser = new AutoDetectParser();
	    Metadata metadata = new Metadata();
	    try (InputStream stream = AutoDetectParseExample.class.getResourceAsStream("Hello.txt")) {
	        parser.parse(stream, handler, metadata);
	        return handler.toString();
	    }
	}
}

Output:

Following is the content of hello.txt file after extraction.
