How do you break a Monolith into Microservices at Scale? This ebook shows strategies and techniques for building scalable and resilient microservices.

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:

Strings in switch

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


Diamond operator (new LinkedList<>())

  • 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

JSR 292 (Exotic identifiers)

  • 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


Automatic resource management

  • convert to ARM hint


New parser

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:
