Is there a way to ignore the 'Unreachable statement' error?

Is it possible to somehow ignore this error? I find it much easier to just put return in front of the code I don't want to run than to comment it (when the comments overlap and behave badly)...

33. if (1==1) return;
34. System.out.println("Hello world!");

It works in other languages too. But ByteCode without row 34.

If you want disable/enable certain piece of code many times trick from old C may help you:

some_code();
more_code();
// */

/*
some_code();
more_code();
// */

Now you need only to write /* at the beginning

No. It's a compile time error. So you must get rid of it before running your class.

What I usually do is put a fake if statement in front of it. Something like:

if(true)
    return;
// unwanted code follows. no errors.
i++;
j++;

With this code, you will not get a Unreachable statement error. And you will get what you want.

you have to fix that unreachable code.

public void display(){
  return; //move the return statement to appropriate place
  int i;
}

compiler will not compile your source code. you have to take care of your source code that every line is reachable to compiler.

It isn't possible to ignore this error since it is an error according to the Java Language Specification.

You might also want to look at this post: Unreachable code error vs. dead code warning in Java under Eclipse?
