1. API Contents
•Develop code that uses the primitive wrapper classes (such as Boolean, Character, Double, Integer, and so on), and/or autoboxing & unboxing. Discuss the test differences between the String, StringBuilder, and StringBuffer classes.
•Given a scenario involving navigating file exam systems, reading from files for 1Z0-852, writing to files, or interacting with the user, develop the correct solution questions using the following classes (sometimes in combination), from java.io: BufferedReader, BufferedWriter, File, FileReader, FileWriter, PrintWriter, and Console.
•Develop code that serializes and/or de-serializes objects using the test following APIs from java.io: DataInputStream, DataOutputStream, FileInputStream, FileOutputStream for 1Z0-852, ObjectInputStream, ObjectOutputStream and Serializable.
•Use standard J2SE APIs in the java.text package to correctly format questions or parse dates, numbers, and currency values for a specific locale; and, given a scenario, determine the test appropriate methods to use if you want to use the default locale or a specific locale. Describe the purpose and use of the java.util.Locale class for 1Z0-852.
2. OO Concepts
•Develop code that implements tight encapsulation, loose coupling exam, and high cohesion in classes, and describe the benefits for 1Z0-852.
•Given a scenario, develop code that exam demonstrates the use of polymorphism questions. Further, determine when casting will be necessary and recognize compiler as compared to runtime errors related test to object reference casting.
•Explain the effect of modifiers on inheritance questions with respect to constructors, instance or static variables, and instance or static methods.
•Develop code that implements "is-a" and/or "has-a" relationships.
3. Fundamentals
•Given an example of a class and a command-line, test determine the expected runtime behavior.
•Given the fully-qualified name of a class that is deployed exam inside and/or outside a JAR file, construct the appropriate directory structure for that class. Given a code example questions and a classpath, determine whether the classpath will allow the code to compile successfully for 1Z0-852.
