Understand the behavior of flatMap() when flattening nested collections.

The updated version of the IKM Java 8 test shifts focus away from rote syntax memorization. It now emphasizes production-grade code analysis, edge cases, and the functional paradigms introduced in Java 8. Functional Programming & Lambda Expressions To pass the updated IKM Java 8 exam

If a method is overloaded with a primitive int , a wrapper Integer , and a varargs parameter ( int... ), you must know the exact priority order the JVM uses to resolve the method invocation. Exact primitive match Widening (e.g., int to long ) Autoboxing (e.g., int to Integer ) String and Object Immutability

Generics, standard collection frameworks, and NIO (New I/O). Critical Test Rules (Avoid Instant Suspension) the compiler throws an error.

This is the heart of the Java 8 update. You will likely face complex scenarios involving: Intermediate vs. Terminal operations.
