Is there a Java equivalent to C#'s 'yield' keyword?

Question

I know there is no direct equivalent in Java itself, but perhaps a third party?

It is really convenient. Currently I\'d like to implement an iterator that yields all

Answer 1

Stream.iterate(seed, seedOperator).limit(n).foreach(action) is not the same as yield operator, but it may be usefull to write your own generators this way:

import java.util.stream.Stream;
public class Test01 {
    private static void myFoo(int someVar){
        //do some work
        System.out.println(someVar);
    }
    private static void myFoo2(){
        //do some work
        System.out.println("some work");
    }
    public static void main(String[] args) {
        Stream.iterate(1, x -> x + 1).limit(15).forEach(Test01::myFoo);     //var1
        Stream.iterate(1, x -> x + 1).limit(10).forEach(item -> myFoo2());  //var2
    }
}
