Currying: Difference between revisions

Or in Java 8:

<lang java8>

import java.util.function.BiFunction;

import java.util.function.Function;

public class Curry {

public static <T, U, R> Function<T, Function<U, R>> curry(BiFunction<T, U, R> biFunction) {

return t -> u -> biFunction.apply(t, u);

}

public static int add(int x, int y) {

return x + y;

}

public static void main(String[] args) {

BiFunction<Integer, Integer, Integer> bif = Curry::add;

Function<Integer, Function<Integer, Integer>> curried = curry(bif);

Function<Integer, Integer> add5 = curried.apply(5);

System.out.println(add5.apply(2));

}

}

</lang>
