Oracle Certified Associate (OCA) Syllabus

# Java Basic

1. Basic Structure of a java class.
2. Define the scope of variables.
3. Create Executable java application with a main method; run a java program from the command line; produce console output.
4. Import other java packages to make them accessible in your code.
5. Compare and contrast the features and components of java such as platform independence, object orientation and encapsulation, etc.

# Using Operators and Decision.

1. Use of java operators; use of parentheses to override operator precedence.
2. Test equality between String and other object using == and equal().
3. Crate If and if/else and ternary operators.
4. Use of switch statement.

# Using Loop

1. Create and use of while loops.
2. Create and use of loops including enhanced for loop.
3. Create and use of do/while loops.
4. Compare loop.
5. Use of break and continue.

# Java data type

1. Declare and initialise variable.
2. Differentiate between Object reference, variable and primitive variable.
3. Explain an Object life cycle (Creation , de-reference by reassignment and garbage collection).
4. Develop Code that uses wrapper classes such as Boolean, Double and Integer.

# Creating and Using Arrays

1. Declare, Instantiate, initialize and use one dimension / multi-dimensional arrays.

# Inheritance

1. Describe inheritance and it’s benefits.
2. Use of polymorphism; method override, differentiate between the type of a reference and the type of an object
3. Determine when casting is necessary
4. Use of super and this to access objects and constructors
5. Use of abstract classes and interfaces

# Encapsulation

1. Create methods with arguments and return values; including overloaded methods.
2. Use of static keyword to methods and field.
3. Create and overload constructors; differentiate between default and user defined constructors
4. Apply access modifiers
5. Apply encapsulation principles to a class
6. Determine the effect upon object references and primitive values when they are passed into methods that change the values

# Exception Handling

1. Differentiate among checked exceptions, unchecked exceptions, and Errors
2. Create a try-catch block and determine how exceptions alter normal program flow
3. Describe the advantages of Exception handling 
4. Create and invoke a method that throws an exception
5. Recognize common exception classes (such as NullPointerException, ArithmeticException,  ArrayIndexOutOfBoundsException, ClassCastException )

# Working with selected classes from Java API

1. Use of the StringBuilder class and its methods
2. Create and manipulate Strings
3. Create and manipulate calendar data using classes from java.time.LocalDateTime, java.time.LocalDate , java.time.LocalTime, java.time.format.DateTimeFormatter,   java.time.Period
4. Declare and use an ArrayList of a given type
5. Write a simple Lambda expression that consumes a Lambda Predicate expression

# Assume the following

1. Missing package and import statements: If sample code do not include package or import statements, and the question does not explicitly refer to these missing statements, then assume that all sample code is in the same package, or import statements exist to support them.
2. No file or directory path names for classes: If a question does not state the file names or directory locations of classes, then assume one of the following, whichever will enable the code to compile and run:
• All classes are in one file
• Each class is contained in a separate file, and all files are in one directory
3. Unintended line breaks: Sample code might have unintended line breaks. If you see a line of code that looks like it has wrapped, and this creates a situation where the wrapping is significant (for example, a quoted String literal has wrapped), assume that the wrapping is an extension of the same line, and the line does not contain a hard carriage return that would cause a compilation failure.
4. Code fragments: A code fragment is a small section of source code that is presented without its context. Assume that all necessary supporting code exists and that the supporting environment fully supports the correct compilation and execution of the code shown and its omitted environment.
5. Descriptive comments: Take descriptive comments, such as "setter and getters go here," at face value. Assume that correct code exists, compiles, and runs successfully to create the described effect.
