SKILL BENCHMARK

Java Certified Foundations Associate Proficiency

  • 25m
  • 25 questions
The Java Certified Foundations Associate Proficiency benchmark assesses your knowledge of handling exceptions and debugging your Java code. You will be evaluated on your skills in recognizing how Arrays and Arraylist are designed to handle looping through lists of data, and working with LinkedList, the HashMap, and the HashSet classes. A learner who scores high on this benchmark demonstrates that they have the skills to work with interfaces and static members, and can create and instantiate a class with and without constructor parameters and modify the object fields.
