Course Outline
Introduction
- JVM, JRE, and JDK for government
- Integrated Development Environment (IDE) selection and setup
- Compilation and execution of Java code in a secure environment
Java Syntax
- Packages and their role in organizing code for government applications
- Variables, arrays, and data types used in government systems
- Operators and control flow structures for efficient coding practices
- Enumeration details for managing discrete sets of values
Object-Oriented Programming
- Classes and objects: foundational concepts for building robust applications
- Class constructors: initializing objects with necessary parameters
- Inheritance, overloading, and overriding: enhancing code reuse and flexibility
- Access modifiers: controlling visibility and access to class members
- Abstract classes: defining templates for subclasses in government projects
- Interfaces: specifying behaviors that multiple classes can implement
Java Collection Framework
- Collections vs arrays: understanding the differences and appropriate use cases
- Lists, maps, queues, and sets: core collection types for managing data efficiently
- Maps: key-value pairs for fast lookups and associations
- Equals and hashCode contract: ensuring consistent behavior in collections
- Sorting: organizing data for easier access and analysis
Exception Handling
- Class Throwable: the base class for all exceptions and errors
- Checked and unchecked exceptions: managing predictable and unpredictable errors
- Throwing an exception: explicitly signaling error conditions
- 'try...catch' statements: handling exceptions gracefully in government applications
- Creating custom exceptions: defining specific error types for unique scenarios
Input/Output API
- Working with input and output streams: managing data flow securely
- Byte vs character streams: understanding different data handling methods
- File Handling: reading from and writing to files in a secure manner
- Object Serialization: converting objects to a format suitable for storage or transmission
- NIO.2: advanced file and network operations for improved performance
Java Concurrency
- Threads and concurrency: enabling multiple tasks to run simultaneously in government systems
- Thread class vs Runnable interface: choosing the right approach for concurrent execution
- Running tasks using ExecutorService: managing thread pools for efficient task management
- Synchronizing threads: ensuring data consistency and preventing race conditions
Requirements
Knowledge of procedural programming languages (such as C, PHP, Basic, Pascal) or object-oriented programming languages is required for government applications and projects.
