What does "void" mean in "public void" ?

Hi everyone, sorry for asking too many questions because I'm new to java and other programming languages.

I have managed to browse google and still confused about void.

what does this "public void" mean compared to just "public"?

Thanks!

In, Java

  • void keyword means that the function/method has no return value.
  • public void, now this is 2 keywords here, void has been explained in the previous line; and public keyword is an access level modifier.

From Oracle Java doc https://docs.oracle.com/javase/tutorial/java/javaOO/accesscontrol.html

A class may be declared with the modifier public, in which case that class is visible to all classes everywhere. If a class has no modifier (the default, also known as package-private), it is visible only within its own package
