While I was working on the samples for this post using the Nebeans nightly builds with support for Lambda Expressions downloaded from here. I found that the IDE gave good suggestions for converting the code to use the Java 8 support as and where possible. For example I had a small piece of code:

List<Person> olderThan30OldWay = new ArrayList<>();
for ( Person p : personList){
  if ( p.age >= 30){

and the IDE showed an yellow line under the for and provided a hint as shown in the screenshot below:
and using the hint resulted in the following code being added in place of the above code:

List<Person> olderThan30OldWay = new ArrayList<>();
personList.stream().filter((p) -> ( p.age >= 30)).forEach((p) -> {

This is going to be really useful for people to identify where the code can be replaced by Lambda Expression. A more detailed intent of experimenting with the above sample can be found in my previous post here.
