Beginning
- The importance of Java and its origins.- What does the article deal with?
- Brief coverage on the organization of the article.
Part 1: What comes into your mind when you hear the word Java?
1. What is this programming language?
- The programming language and its origins.
- Its relative position in the hierarchy of programming languages.
- The core of the Java and the overview of its architecture (JVM, JDK, JRE).
2. Off to the Java Development Kit
- Downloading and installing development environments e.g., IntelliJ IDEA, Eclipse, or NetBeans.
- Installing JDK and setting up system path.
- Basic understanding of command line tools (javac, java, jar).
3. Introduction to the vast world of Java
- Scope and scale of variables, data types and their operations.
- Control flow (If-else, switch-case, for-while loops etc.)
- Functions and their importance in function-oriented programming.
4 Classes and Objects
- Explanation of definition of classes and the processes of instantiating objects
- Introduction to why constructors and initialization blocks are used.
– The concept of encapsulation and common access modifiers or access control keywords (public,private,protected) with examples.
5 Inheritance and Polymorphism
- The concept of extending a class and overriding one or more methods.
- The reasons defining the purpose of abstract classes and interfaces in an ‘is-a’ hierarchy.
- Description of Method overriding and Dynamic dispatch as a form of Polymorphism.
6 Exception Handling
- How to handle exceptions using try and catch and why a ‘finally’ clause is used.
- Throw and create for user-defined exceptions.
Part 3: Java Programming in Depth
7. Collections Framework– Basics of Java Collections encompassing List, Set, Map, etc, and its elements.
– Advantages of iterator and enhanced for loop.
– Carrying out operations using ArrayList, LinkedList, HashSet and HashMap.
8. Generics
– Need for genrics and explanation of type parameters.
– Wildcards and bounded type arguments.
– Using generics in collections and in designing classes.
9. Concurrency in Java
– What is a thread and how those threads can be synchronized in a basic way.
– Occurrence of concurrent collection and its utilities such as ConcurrentHashMap and CountDownLatch.
– Executor framework and the worls of thread pools.
Section 4: Implementing Applications in Java
10. Creation, Reading and Writing, and Serialization of Files- Implementing input and output files functionality with streams (FileInputStream, FileOutputStream).
- Converting given data objects to bytes and vice versa (ObjectInputStream, ObjectOutputStream).
11. Importing Java Networking and Sockets
- A step to step tutorial on implementing application communication by way of using sockets (ServerSocket, Socket).
- Implementation of client-server architecture.
12. Database Connectivity with JDBC
- Making a connection to the relational databases (MySQL, PostgreSQL) through ‘jdbc’.
Part 5: Java Frameworks and Tools
13. Getting acquainted with Spring Framework
– Basic Structural Components of Spring Core, Spring MVC, and Spring boot.
– Context, interfaces in spring.
14. Introduction to Java EE (Enterprise Edition)
- Brief on the Struts, EJB, servlets, and JSP and how they relate to Java EE.
- The workings of web applications from the Java EE perspective.
15. Unit Testing with JUnit
- Write out unit test cases and execute them through Junit.
- The principles behind TDD application development.
- Executing Data Manipulation Language commands and controlling their state.
Section 6: More Elaborate Subjects and Standards
16. Patterns of Design- Among many commonly applied design patterns Singleton, Factory, and Observer etc.
- The application of design patterns to Java applications.
17. Attaining Performance Efficiency
- Java application performance profiling.
- Memory management including garbage collectors.
18. Security: Practices to Follow
- Secure programming (ie. all input validated and all output encoded).
- Overview of Java Security APIs, tools and framework.
In Summary
