When would you put a semicolon after a method closing brace?

Question

I\'ve been programming in Java for a while, and I\'ve just come across this syntax for the first time:

public Object getSomething(){return something;}; 
         


        

Answer 1

It's allowed by the grammar as a concession to harmless syntax errors, but it's not generally used and doesn't mean anything different (than leaving the semicolon out).

Just as a }; inside a method (such as after an if block) is a null statement and is allowed, an errant semicolon outside a method is considered a null declaration and is allowed.

Specifically, the following production from the Java Language Specification allows this:

ClassBodyDeclaration:
  ; 
  [static] Block
  ModifiersOpt MemberDecl
