回答1:
No. Helios does not support Java 7 syntax. It is also an over three year old product. Kepler just came out. Last year Juno came out. The year before Indigo came out. Before THAT Helios came out.
Why can't you upgrade your Eclipse?
回答2:
Eclipse uses its own internal compiler and not javac from the JDK.
Hence you need a version of Eclipse officially supporting Java 7 which Helios doesn't. I would suggest the latest version of Eclipse Juno (4.2) and not the brand new Kepler (4.3) because it has had a year of bug fixes.

Try to switch to Juno version http://www.eclipse.org/downloads/
