How Can I Decode HTML Entities in Java?

Decoding HTML Entities in Java

Unescaping HTML character entities in Java allows you to convert special characters, such as "" " and "">"," back to their original Unicode characters. In .NET, this is achieved using the HttpUtility.HtmlDecode method.

Java Equivalent

Java does not provide a direct equivalent to the .NET HttpUtility.HtmlDecode method. However, you can use third-party libraries like Apache Commons Lang to achieve this functionality.

Solution Using Apache Commons StringEscapeUtils

import org.apache.commons.lang3.StringEscapeUtils;

String html = "" "">";
String unescapedHtml = StringEscapeUtils.unescapeHtml4(html);

System.out.println(unescapedHtml); // Outputs: " " >

The StringEscapeUtils.unescapeHtml4() method decodes HTML 4.0 entities, converting special characters back to their Unicode representations.
