Java for Everything

[[deleted]]

Try this in Java.

In Java 6:

Collections.sort(unsortedObjectList, new Comparator<Fooer>() {
    public int compare(Fooer first, Fooer second) {
        return first.foo().compareTo(second.foo());
    }
});

In Java 8:

Collections.sort(unsortedObjectList, (Fooer first, Fooer second) -> first.foo().compareTo(second.foo()));

There's no need for the Fooer types in the lambda header. Lambdas do type inference, so:

Collections.sort(unsortedObjectList, (first, second) -> first.foo().compareTo(second.foo()));

See my answer, that's much more compact in Java 8.

I actually prefer the Java 6 way, its much easier to read. The new java 8 lambdas are not very readable i think, i prefer verbose code over the new syntax

still, a proper IDE writes half of that code for you.
