Trivial usage of functional expression
Reports functional interface methods calls that are directly invoked on the definition of the lambda, method reference, or anonymous class. Such method calls can be replaced with the body of the functional interface implementation.
Example:
boolean contains(List<String> names, String name) {
return ((Predicate<String>)x -> {
return names.contains(x);
}).test(name);
}When the quick-fix is applied, the method call changes to:
boolean contains(List<String> names, String name) {
return names.contains(name);
