How to remove all unnecessary semicolons (at end of blocks)?

Some of our code written a while have unnecessary semi-colon. I wonder whats the easiest way to remove them. For example, the last semi-colon in the following 

 if(i == 2)
   {
       System.out.println("if statement");
   }
   else
   {
       System.out.println("else statement");
   };

It may be too late for you but this could help others:

CTRL + F

write what you want to delete in your case ; and then:

CTRL + ALT + SHIFT + J

This will select all the matches for your search in that file.

Then you just have to delete DELETE

It is probably too late for you but, you can Analyze your code with Intellij IDEA using the Inspection "Unnecessary semi-colon" then after it has found them all you can apply the Fix.

http://www.jetbrains.com/idea/documentation/inspections.jsp

Eclipse can also do this too but it suffers from a bug that doesn't allow you to apply the Quick Fix in bulk.

As the above said, by typing ctrl + f and searching for }; and replacing it with } would work great, but could break the code.

They are not necessary to be removed, as it is just the equivalent of:

if(true){
  //...
}
/*Empty Line*/;

It won't effect the code in any way, but is best to remove them just for preference.

You can find them easily enough by going into the Java Compiler / Error and Warnings preferences, then under "Potential Programming Problems" change "Empty Statements" to warning or error. Then it'll just be a matter of going through them. There may be a way of automating it, but I wouldn't bother unless there are loads :)
