fix: Missing Javadoc tag

[Umang070]

Bug:
In the code snippet, the @deprecated Javadoc tag is missing. The @deprecated annotation is typically utilized to signal that a method or class is outdated. It's considered good practice to include a Javadoc comment alongside the annotation to give clarity for deprecation and offer recommendations on alternative usage.

Solution:
Add the missing @deprecated Javadoc tag before the function name.
