ParseContext class is a component of the Java package org.apache.tika.parser, which is used to parse context and pass it on to the Tika (The Apache Tika toolkit detects and extracts metadata and text from over a thousand different file types) parsers org.apache.tika.parser.ParseContext implements a Serializable interface.
public class ParseContext extends Object implements Serializable
Constructor:
1. ParseContext() – ParseContext() initialize a new instance of ParseContext class.
ParseContext p = new ParseContext()
Note: p is the new instance of ParseContext class.
