Was trying to compile that sample example in my IDE but I am getting this error.

回答1:
You need to set the source for your project,
right click > properties > source > set here
回答2:
In general on "-source 7": use JDK7
(For example if you are normally using JDK 6 and just want to use JDK 7 for a special project etc.)
If you still have problem to use a different JDK in Netbeans, the following steps may help.
First, install JDK to any directory, it does not have to be your main JDK or entered to any PATHS or so.
All these steps must be regarded
In Netbeans, right-click on the project -> Properties
- -> Libraries -> Manage Platforms... -> Add Platform... and add your JDK directory
- -> Libraries -> Java Platform: select JDK 7
- -> Sources -> Source/Binary Format: select JDK 7

intellij IDE handles itself, just click the red bulb and choose add JDK 7
