TotallyLazy functional code in Java

I am attempting to use the functional library TotallyLazy, in Java. I am programming in AIDE on Android. I have this code which doesn't work:

package net.intrepidis;
import java.util.Comparator;
import static com.googlecode.totallylazy.Sequences.sequence;
import static com.googlecode.totallylazy.comparators.Comparators.ascending;

public class FunctionalTest
{
    public static void Go()
    {
        sequence(34, 25, 62)
            .sort(ascending());
    }
}

If I use this line instead then it works:

            .sort((Comparator<Comparable>)ascending());

However, that looks wrong to me, and goes against the grain of the framework. What am I doing wrong? Is it just because the Java version used by AIDE doesn't allow for the abbreviated code?

Solution

  • You could also do 

    sequence(34, 25, 62)
.sort(Comparators.<Integer>ascending());

    This is useful if the sequence is a generic type
