Key differences between Java and Crystal

Characteristic	Java	Crystal
Syntax	Java uses a C-style syntax with curly braces and semicolons.	Crystal uses a Ruby-like syntax with a focus on readability and simplicity.
Paradigm	Java is primarily an object-oriented programming language with support for imperative and functional programming.	Crystal is a statically-typed, object-oriented language with a focus on simplicity and performance.
Typing	Java is statically-typed, which means that variable types are checked at compile-time.	Crystal is also statically-typed, but it has a type inference system that allows for some dynamic typing.
Performance	Java is known for its performance and is often used for high-performance applications.	Crystal is designed to be fast and efficient, with performance comparable to C or C++.
Libraries and frameworks	Java has a vast ecosystem of libraries and frameworks, including popular ones like Spring and Hibernate.	Crystal has a smaller ecosystem of libraries and frameworks compared to Java, but it is growing steadily.
Community and support	Java has a large and active community with extensive documentation and support resources.	Crystal has a smaller community compared to Java, but it is passionate and supportive.
Learning curve	Java has a moderate learning curve, especially for beginners, due to its strict syntax and concepts like object-oriented programming.	Crystal has a relatively steep learning curve, especially for beginners, due to its focus on performance and advanced features.
