This seems to be a common error and I've used SO resources to make attempts to fix this. I've tried Cleaning the project, refreshing the project, switch workplace and switch back, removed and re-added the JRE7.
I don't know what else to do.

解决方案Since:
1.8
So upgrade to Java 8, or try to find an older version of the tutorial.
I'm new at this. How can you tell what you are running? I'm using Eclipse
To determine your current Java version in eclipse, go to
Help -> About Eclipse -> Installation Details (Button in
lower Left) -> Configuration pane
Look for the line java.specification.version - on my machine that is
java.specification.version=1.8
Or the line java.runtime.version - on my machine that is
java.runtime.version=1.8.0_11-b12
