What Does The Colon Mean In Java?

Question

What does the colon mean in Java? I have this:

public static List findAllAnagrams(List words) {
    List result =          


        

Answer 1

Don't think colon(:) means anything particularly. It's just how Java designers thought to delimit parameter and expression inside improved for loop.

for ( FormalParameter : Expression ) Statement
