It is nothing like the real Java. Almost no regular data type is supported and there are severe limitations. [1]

You should view it as using a safe language instead of something like C. If Rust had been invented 20 years ago, it might have been Rust instead.

The secure element on iOS devices is a Java Card (https://www.apple.com/business/site/docs/iOS_Security_Guide.... p. 47).

Basically all smart cards use Java Card. There's an ISO standard, so I'm sure it's possible to implement your card in other environments, but everyone uses Java Card.
