    Can almost do everything Java can and sometimes a little better.

    Object orientation is just broken in Python with Java standards. Also (Meme-ing a bit here) the idea behind Java... the reason behind Java... the force behind Java...

    is the JVM... (no longer meme-ing) which led and leads to this day to insane portability, reliability and compatibility, backwards and forwards, offered by no other ecosystem in existence. There already is this great rift between Python 2 and 3 and within minor versions of 3 itself.

    C# and Java are almost identical. Besides the fact they're being lead by different companies, they have almost the entirely same performance profile and same syntax.

    C++ is much more low-level and close to C than Java, which can be used more easily to create applications faster. However Java is a bit slower than C++

    Rust is not only much more performant in comparison to Java, but it also has some features other languages like C++ don't, such as memory management through the use of borrow checking and really good pattern matching. All of that coupled with a great package manager and Rust is considered by many to be the low-level language of the future.

    It's very low-level, compared to Java. It's not entirely general purpose like Java.

    C cannot directly be seen as an alternative to Java, because Java focusses on business applications, while C focusses on systems programming. You will not be as productive in C as you can be in Java or its derivate languages. For low-level programming IMHO C is the first choice though. Before complaining that C is outdated remember that even the heart of Java is written in C/C++. Also remember that the software that makes your computer usable in the first place is most likely also written in C.
