how remove @SuppressWarnings(“unused”) in netbeans?

Question

I always see in many codes:

@SuppressWarnings("unused")

How can I remove these lines I use in java (in the NetBeans IDE):

@SuppressWarnings("unused")
String newName1 = input.next();         
@SuppressWarnings("unused")
String newFamily1 = input.next();           
String newGender1 = input.next();           
@SuppressWarnings("unused")
String arrow = input.next();        
@SuppressWarnings("unused")
String newName2 = input.next();         
@SuppressWarnings("unused")
String newFamily2 = input.next();
String newGender2 = input.next();

Delete them. All they are is a hint to the IDE that the local variable is never referenced again. IMO if you're not using them it's a bit misleading to have variables--why not use a real parsing library? — Dave Newton, Jul 08 '12 at 15:46

If you don't actually need the variable and you're just trying to advance input just call input.next() and don't assign it to anything.

Search for it and replace all with ""

You mean execution errors : As far as I can see, you use input.next(). That looks like an Iterator/StringTokenier and it means that you're trying to go beyond the Iterator/StringTokenizer limit. Use if(input.hasNext()/input.hasMore()) newFamily2 = input.next(); – Razvan Jul 08 '12 at 15:43
