JDK 7 Support in NetBeans IDE 7.0

In the upcoming NetBeans IDE 7.0, the user will be able to select JDK 7 as a project's target platform. If this is done, the built-in parser starts using the new compiler (no red underlines for new javac features) and the following set of IDE features are enabled:

• Strings in switch
• Diamond operator (new LinkedList<>())
• java.util.Objects
• JSR 292 (Exotic identifiers)
• Multicatch
• Automatic resource management
• New parser

Details on each of the above are found below:

• code completion updated
• hint converting a cascade of if-elses to switch

• warning when the diamond operator is not used and could be, includes fix to remove the superfluous bounds
• tooltip in hyperlink (Ctrl-point to the identifier) shows inferred bounds

• equals and hashcode generator (Alt-Insert, "equals() and hashCode()") uses java.util.Objects.equals/hashCode if available

• exotic identifiers supported in semantic highlighting, mark occurrences and Go to Declaration
• suggestion to convert an integer constant to a different radix can also convert to binary literal

• code completion works in the multicatch variable declaration
• hint to join multiple catches into one multicatch if the handling code is the same
• fix for the error if the multicatch variable is not final

• convert to ARM hint

As mentioned, the built-in parser recognizes the new syntax. In the following screenshot, all the hints from the previous screenshots have been applied to yield the final result:
