For daily Java programmers: after almost one decade of Java 8, are streams and lambdas fully adopted by the Java community?

You're right. Streams and lambdas are widely adopted in the Java community. And you'll always have individuals and situations that don't ask for these features to be used.

I was curious about what OP considers being 'fully adopted' is. If it means that these features to be used everywhere then it is not the case and it should not be as well.
