Semicolon at end of 'if' statement

Question

Today, after half an hour of searching for a bug, I discovered that it is possible to put a semicolon after an if statement instead of code, like this:

if(a          


        

Answer 1

A possible use case:

if (a==b);
else {
  // Do something
}

Not good, but possible.

Still, I do think that the Java specification should disallow an empty if.
