11 maj 2024 · Encoding a String into UTF-8 isn’t difficult, but it’s not that intuitive. This article presents three ways of doing it, using either core Java or Apache Commons Codec. As always, the code samples can be found over on GitHub. Learn how to encode a Java String to the UTF-8 character set.

In the absence of file.encoding attribute, Java uses “UTF-8” character encoding by default. Character encoding basically interprets a sequence of bytes into a string of specific characters.
The java.io.InputStreamReader, java.io.OutputStreamWriter, java.lang.String classes, and classes in the java.nio.charset package can convert between Unicode and a number of other character encodings. The supported encodings vary between different implementations of Java SE 8.
