How about these:

Similarities

As in Java, in Ruby, ...

  • The memory is managed for you through the garbage collector.
  • Objects are strongly typed.
  • Public, private, and secure methods exist.
  • There are built-in doc tools (Rubys is called RDoc). The documents created by rdoc are very similar to the documents created by javadoc.

Differences

Unlike Java, in Ruby, ...

  • You do not need to compile your code. You just run it directly.
  • - . .

Therefore, I can say that in Java and Ruby there is not too much in common. Until today, I cannot find any similarities between them, since Ruby has gone its own way, unlike many other languages ​​that come from C.
