android - Can't work on my java projects in Eclipse Juno -

i used work in eclipse luna , had many projects in workspace. decided start coding android , downloaded adt bundle here. imported luna workspace , worked fine. however, whenever open class cannot resolved errors everywhere on used flawless code. difference in packages causing this? why can't write , compile java in juno?

note don't see errors in bundle explorer on left:

your jdk missing or incorrect. check in ur build path of project. jre still referencing old location.

java android eclipse
