How to create optional class in java?

Great question! Java's Optional class was introduced in Java 8 to help deal with null values more elegantly. Here's how to create and use them:

Creating Optional objects: ```java // Empty Optional Optional emptyOpt = Optional.empty();

// Optional with non-null value Optional nameOpt = Optional.of("John");

// Optional that might be null String possibleNull = getStringThatMightBeNull(); Optional maybeName = Optional.ofNullable(possibleNull);
