What is the difference between public void and void methods?
This question already has an answer here:
This has already been answered here: In Java, difference between default, public, protected, and private
Without specification of an access modifier the access is determined by the classes location within the package hierarchy. Similar to public, but not the same by any means.
With public void the word "public" is not a return type. The public is an access modifier in Java.
The following table shows the access to members permitted by each modifier; there are four
public
(none / blank) "package" level
protected
private
Access Levels
|Modifier |Class|Package|Subclass|World| ------------------------------------------ |public | Y | Y | Y | Y | ------------------------------------------ |protected | Y | Y | Y | N | ------------------------------------------ |no modifier| Y | Y | N | N | ------------------------------------------ |private | Y | N | N | N | ------------------------------------------
public is a visibility modifier, in this case there would be no limitation on which classes can access the method
void is a return type, void means the method doesn't return anything to the caller.
