Change JRE in NetBeans project

问题

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.

回答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 Tools->Java Platform Manager.
• If JDK 1.6 is not in the list you can add it there.

回答2:

In Netbeans 8.2,

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

回答3:

There is a bug in NetBeans 8.0.2

When undertaking the above steps 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:
