Using Java 8 to convert a list of objects into a string obtained from the toString() method

Question

There are a lot of useful new things in Java 8. E.g., I can iterate with a stream over a list of objects and then sum the values from a specific field of the Object

Answer 1

There is a method in the String API for those "joining list of string" usecases, you don't even need Stream.

List myStringIterable = Arrays.asList("baguette", "bonjour");

String myReducedString = String.join(",", myStringIterable);

// And here you obtain "baguette,bonjour" in your myReducedString variable
