import java.util.function.Function;

public class Main {

  public static void main(String[] args) {

    Function<Integer,Double> centToFahrenheitInt = x -> new Double((x*9/5)+32);
    double fahrenheit = centToFahrenheitInt.apply(100);
    System.out.println("Centigrade to Fahrenheit: "+fahrenheit);
  }

}
