Very true, in Java, at least in the last 20 years, inheritance is de-facto deprecated, all new bits and bolts like enums, annotations, lambdas or records do not support inheritance.
So you have to use composition.

How is composition in Java inconvenient?
The common toolkits today (spring boot, google guice, etc) are much more focused on composition over inheritance, by injecting arguments and implementing pure interfaces rather than extending base classes. Older legacy Java frameworks and bad teachers are more at fault than the Java language itself IMO.
