Change JRE in a NetBeans project

Question

I have a NetBeans project which is using the JRE 1.4 environment which means I can't use generics.

How can I change the project to use 1.6(?), so I can use generics?

Answer 1

• In the Project tab, right-click on the project and select Properties. In the Library category select Java Platform JDK 1.6.
• Then, in the Source category select Source/Binary Format JDK6.
• This assumes that you installed JDK 1.6 and NetBeans knows about this.
• JDK 1.6 must be known to NetBeans as a Java Platform.
• From the menu select menu Tools → Java Platform Manager.
• If JDK 1.6 is not in the list, you can add it there.

Answer 2

In NetBeans 8.2,

• right click the project, and select Properties
• under the menu build/compile, select the Java platform from the drop down menu

Answer 3

There is a bug in NetBeans 8.0.2

When undertaking the steps in OliBlogger's answer in changing JRE or JDK for a project, NetBeans attempts to save the project with the new JDK (9 in this instance), but it goes into an infinite loop and eventually gives an OutOfMemoryError:
