Hi, you may refer to #309

[brendancjz]

BiFunction<Character, String, Integer> s = new BiFunction<Character, String, Integer>() { public Integer apply(Character c, String s) { return (c + s).length(); } }

[Herrekt]

I got about the same here BiFunction<Character, String, Integer> s = new BiFunction<Character, String, Integer>() { @Override public Integer apply(Character c, String s) { return (c + s).length(); } };

[Radix-huang]

same BiFunction<Character, String, Integer> s = new BiFunction<Character, String, Integer>() { public Integer apply(Character i, String j) { return (i + j).length(); } }
