Java - convert predicate to string

Question

I would like to know if there is a way to convert Predicate to String . For example, there will be a function:

 public static <T> String convertPredicate(Predicate<T> objPredicate) { return ?... } 

So that the next call returns (obj) -> obj.value== 1 :

 convertPredicate((obj) -> obj.value== 1) 

Answer 1

No, in general, this is not possible in Java. You can try to analyze and decompile the bytecode of the lambda class (although getting the bytecode of this class is already a really non-trivial task), but such a solution would be very complicated and fragile. The specific representation of lambda is not specified at runtime and may change in different versions of Java or different JDK providers.
