Answer 1

You need to set the source for your project,

right click> propertiesa> source> set here

Answer 2

Generally on "-source 7": use JDK7

(For example, if you usually use JDK 6 and just want to use JDK 7 for a special project, etc.)

If you still have a problem using a different Netbeans JDK, the following steps may help.

First, install the JDK in any directory; it should not be your main JDK or entered in any PATHS or so.

All these steps should be considered.

In Netbeans, right click on the project -> Properties

• → Libraries → Platform Management ... → Add Platform ... and Add JDK Directory
• → Libraries → Java Platform: Select JDK 7
• -> Sources -> Source / Binary Format: select JDK 7

Answer 3

Intellij IDE handles itself, just click on the red light and select add JDK 7
