Differences

The following are some key differences between Java and Rust.

Characteristic	Java	Rust
Syntax	Java has a verbose syntax with a lot of boilerplate code, while Rust has a concise syntax with a focus on safety.	Rust has a concise syntax with a focus on safety, while Java has a verbose syntax with a lot of boilerplate code.
Paradigm	Java is primarily an object-oriented language, but also supports functional programming paradigms.	Rust is a multi-paradigm language that supports functional, imperative, and object-oriented programming paradigms.
Typing	Java is a statically typed language with type inference.	Rust is a statically typed language with type inference and strong, safe, and flexible typing.
