Use diamond operator
** org.openrewrite.java.cleanup.UseDiamondOperator** The diamond operator (<>) should be used. Java 7 introduced the diamond operator (<>) to reduce the verbosity of generics code. For instance, instead of having to declare a List's type in both its declaration and its constructor, you can now simplify the constructor declaration with <>, and the compiler will infer the type.
