To be sure you need to download java from http://jdk8.java.net/lambda/.

Re. Collections support. Basic lambda examples are working for me. When I tried to do something simple like List.forEach {} it doesn’t compile. It appears it’s not part of the latest jdk 8 build yet, but I may be missing something. Does this work today?

Davide, what support do you expect? Thanks

is there already also support for map, filter and reduce operations on collections? Looks great anyway! Great job.

Works here. Could you please check that your module has 1.8 language level. Otherwise IDEA would treat lambdas as unsupported feature, hence no intention would be suggested.
Thanks

public class MyClassTest extends TestCase {
public void testFoo() {
Comparable integerComparable = new Comparable() {
@Override
public int compareTo(Integer o) {
return 0;
}
};
}
}

does not offer an intention.

Any ideas?

Hi,
actually this code
{code}
Set strs = new TreeSet();
strs.add(”");
for (String str : strs) {}
{code}
should not compile (and is highlighted in IDEA) as ’strs’ has raw type and cant be converted without cast to Set.
On the other hand code
{code}
Set strs = new TreeSet((o1, o2) -> {
return o2.compareToIgnoreCase(o1);
});
{code}
compile but is highlighted in the IDE. Will investigate the problem. Thanks

Thank you Anna

It works.

Regarding the other issue, is it a JDK-1.8 issue or IDE one?

Regards

What’s the font in the picture?
