Reports lambda expressions that can be replaced with anonymous classes.

Expanding lambda expressions to anonymous classes may be useful if you need to implement other methods inside an anonymous class.


s -> System.out.println(s)

After the quick-fix is applied:

new Consumer<String>() { @Override public void accept(String s) { System.out.println(s); } }

Lambda expression appeared in Java 8. This inspection can help to downgrade for backward compatibility with earlier Java versions.
