StringBuilder cannot be resolved to a type?

[julio]

Hi,

like in subject, I get this error when I compile my app that uses
StringBuilder.

Why? StringBuilder cannot be used in GWT (I'm using 1.4RC)?

Thanks,
Julio

Hi:

I think that StringBuilder is not supported by GWT.

Is there any reason you need StringBuilder, rather than StringBuffer?

Hi:

>From The Java Docs (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/
StringBuilder.html):

StringBuilder:

"A mutable sequence of characters. This class provides an API
compatible with StringBuffer, but with no guarantee of
synchronization. This class is designed for use as a drop-in
replacement for StringBuffer in places where the string buffer was
being used by a single thread (as is generally the case)."

So the answer is no, you don't need it.

GWT doesn't support Java 1.5 anyway. Stick to Java 1.4 classes.
