This is Java 8.
<lang java>import java.util.function.*;
import java.util.stream.*;
public class Jensen2 {
static double sum(int lo, int hi, IntToDoubleFunction f) {
return IntStream.range(lo, hi).mapToDouble(f).sum();
}
public static void main(String args[]) {
System.out.println(sum(1, 100, (i -> 1.0/i)));
}
}
</lang>
The program prints '5.17737751763962'.
