UpCodeIn - Source code search engine for syntax elements of Java, JS...

In my everyday work as Java programmer, I often have to write a piece of java code that accomplishes a simple task, something many of us have written many times before, a boring piece of code. I don't want to write the same code again, I don't remember what parameters the method has, annotations, regex, IO operations on files, etc. Usually in this situation I use Google to quickly give me a fragment of such code. But here comes the problem - I get code fragments that do not suit my needs because Google as a text search engine does not distinguish the meaning of the searched text in the context of Java code. When I look for userId as a method parameter, it gets userId examples as a variable, etc. That is why a source code search engine was created where you can search for specific keywords in Java language syntax. You can search code for identifier (name) of method, annotation or variable, type, imports, superclass, modifier, exception, field, parameter name or value, enum and more.
