📚 Learning and experimenting with the Java Collections Framework.

---

The Java Collections Framework is the name that Java uses, but I'm not sure I've ever heard this name used in conversation. Instead, I just think about Java's standard library classes like List, Set, Iterator, etc.

Instructions

• Use Java 16
• Build and run the program:
  • java src/dgroomes/Main.java
  • Alternatively, execute it from within an IDE like Intellij.
  • It should print:

    CountingIterator{elementsVisited=1} message: 'Hello'
    CountingIterator{elementsVisited=2} message: 'there,'
    CountingIterator{elementsVisited=3} message: 'world!'
    

Reference

• The Java Tutorials: Trail Collections
  • As always, Java's official guide–The Java Tutorials–are a great way to learn about core features of Java.
