Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

is there premade function that gets mathematical Strings ( for example "(3+4+5)/sqr(20)") and returns result
Not built in to the Java language or SDK, but there's open source libraries such as https://github.com/sbesada/java.math.expression.parser that will do what you want.
-
Can't figure out "java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double" error
You might then want to use some specific math parser Java library. E.g. this sbesada/java.math.expression.parser.

Things I didn't know about Java: Generic Constructors
As I have never seen generic constructors before I wanted to know how "real-world" code uses them. So I wrote a program that parses the Java files in the JDK source code. It uses the JavaParser open-source library. Since its README file mentions Java 15, I ran the program on tag jdk-15+36 of the JDK source code.

Static Analysis at GitHub
GitHub released a pretty good java parser that I think is is related to this work https://github.com/javaparser/javaparser
I'm also using that parser using for a side project where developers can cross link their source code and host them statically: https://github.com/josephmate/OdinCodeBrowser#readme

Automatically unlocking concurrent builds and fine-grained caching for Java with dependency inference
So after taking a deeper look into the docs I've seen that analysis is done via https://github.com/javaparser/javaparser/ lib which has currently only support up to JDK14 (not JDK15, JDK16 nor JDK17...maybe JDK18)...Unfortunately I have not found a full working example for a Java build ...can you give a link?

Bulk Refactoring of Java Code
Depending on the type of refactorings needed, you may be able to use something like Java parser to read the code, refractor it, and write it out again.
What are some alternatives?
aviatorscript - A high performance scripting language hosted on the JVM.
Spoon - Spoon is a metaprogramming library to analyze and transform Java source code. :spoon: is made with :heart:, :beers: and :sparkles:. It parses source files to build a well-designed AST with powerful analysis and transformation API.
ExprTK - C++ Mathematical Expression Parsing And Evaluation Library https://www.partow.net/programming/exprtk/index.html
Lombok - Very spicy additions to the Java programming language.
MathParser.org-mXparser - Math Parser Java Android C# .NET/MONO (.NET Framework, .NET Core, .NET Standard, .NET PCL, Xamarin.Android, Xamarin.iOS) CLS Library - a super easy, rich and flexible mathematical expression parser (expression evaluator, expression provided as plain text / strings) for JAVA and C#. Main features: rich built-in library of operators, constants, math functions, user defined: arguments, functions, recursive functions and general recursion (direct / indirect). Additionally parser provides grammar and internal syntax checking.
rewrite - Automated mass refactoring of source code.
ExpressionEvaluator - A Simple Math and Pseudo C# Expression Evaluator in One C# File. Can also execute small C# like scripts

JHipster - JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."
