Return Lambda from Method in Java 8?

Question

I have just begun to use Java 8 and I am wondering if there is a way to write a method that returns a Function?

Right now I have method like below:

Function<Integer, String> getMyFunction() {   return new Function<Integer, String>() {     @Override public String apply(Integer integer) {       return "Hello, world!"     }   }  } 

Is there a way to write that more succinctly in Java 8? I was hoping this would work but it does not:

Function<Integer, String> getMyFunction() {   return (it) -> { return "Hello, world: " + it }  } 

Answer 1

Get rid of your return statement inside of your function definition:

Function<Integer, String> getMyFunction() {     return (it) -> "Hello, world: " + it; }
