What are some common Java idioms I should know?

Common Java idioms include using the enhanced for loop, the singleton pattern, and the builder pattern. Would you like examples?

Yes, please provide examples of the enhanced for loop and the singleton pattern.

Sure! The enhanced for loop is used to iterate over collections. For example: for (String item : list) { System.out.println(item); }. The singleton pattern ensures a class has only one instance, like this: public class Singleton { private static Singleton instance; private Singleton() {} public static Singleton getInstance() { if (instance == null) { instance = new Singleton(); } return instance; } }.

That's helpful! Are there any other idioms that improve code readability?

Absolutely! Using meaningful variable names, the Optional class for handling nulls, and method references can greatly enhance readability.
