How to Study for the Java Foundations Junior Associate exam

June 7th, 2015 by Jeanne Boyarsky

 

Oracle’s Java Foundations Junior Associate exam is brand new (in beta at the time of this post). Since this isn’t an upgraded version of an existing exam, it’s going to take time for books to come out on the topic.

I took the beta today to see if Scott and my OCA 8 book could be used study. The answer is yes supplemented by a few other things. (In the interest of disclosure, this is true of any OCA 7 book you might have access to as well.)

Before you read any further, see my other post on why I think you shouldn’t take the Junior Associate exam.

Still reading? Ok. If you have your mind set on taking the Junior Associate exam, here’s what you need to know.

Objectives Mapping

This cross references the objectives between the OCA 8 and Junior Associate exam. As you can see, reading an OCA book will put you in good shape. Then there are the “new” objectives:

Objective Topic How to study
1.2 Describe the real-world applications of Java Blog post on real world applications of Java
2.1 Describe the Java Development Kit (JDK) and the Java Runtime Environment (JRE) There’s not much to this.

  • The javac command is used to turn .java (source) files into .class (bytecode files). The javac command is part of the JDK.
  • The java command is used to run .class files. It is part of the JRE.
  • The JDK contains the JRE along with debugging tools and more.
2.4 Compiling and executing a Java program This is covered in OCA books. It isn’t on the OCA exam at the moment so a brief review here:javac Hello.javajava HelloPay attention to the extension (or lack thereof)
6.2 Format Strings using escape sequences including %d, %n, and %s Blog post on formatting Strings
7.1 Use the Random class Blog post on Random and Math
7.2 Use the Math class Blog post on Random and Math
8.4 Compare two String objects by using compareTo Blog post on compareTo
11.3 Traverse the elements of an ArrayList by using iterators Blog post on iterators
