JAVA Development

JAVA is a very popular object-oriented programming language, particularly for client-server web applications. Java is an underlying technology required by many applications and websites and you’ll find it just about everywhere— laptops, data centers, business applications, game consoles, utilities, cell phones and more.

With the prevalence of Java, there is a continued demand for Java programmers. Consult America has the Java training classes for those new to Java as well as higher-level training classes for established programmers.

1. Introduction to Java Programming

  • Stand–alone applications and servlets
  • Compiling source code into bytecode
  • Overview of class libraries

2.Object–Oriented Programming with Java

The object paradigm

  • Encapsulation, inheritance and polymorphism
  • OO analysis and design: “Is a” and “Has a”
  • Designing an OO application step by step
  • Diagramming object structure with Unified Modeling Language (UML)

Java’s object–oriented features

  • Instantiating objects from classes
  • Aggregation and composition
  • Extending existing classes
  • Overloading and overriding methods

3. Structure of the Java Language

Language syntax

  • Declaring and initializing variables
  • Declaring and using arrays
  • Upcasting, downcasting and autoboxing

Flow control

  • Invoking methods and passing parameters
  • Conditionals and loops
  • Handling exceptions with try and catch

Defining classes

  • Fields (instance data)
  • Methods (functions)
  • Abstract classes and interfaces
  • Organizing classes with packages and modifiers
  • Composition vs. inheritance

Building the components of a Java program

  • Leveraging generics with the collections API
  • Developing new classes
  • Compiling and debugging

4. Developing GUIs

Foundations of user interfaces

  • Basic GUI widgets
  • Event–driven programming
  • Benefits of a portable windowing library

Java Foundation Classes (JFC)

  • Creating Swing components
  • Adding Swing components to containers
  • Arranging Swing components using layout managers
  • Dialogs and message boxes

Event handling

  • Registering event handlers
  • Inner classes and top–level classes

5. Storing and Retrieving Data with File I/O

Java streams

  • Streams, Readers and Writers
  • Catching and throwing exceptions
  • Formatting text output

Files and directories

  • Reading and writing files
  • Creating, deleting and renaming files
  • Obtaining directory and file information

6.Working with Relational Databases

JDBC database access

  • Leveraging the JDBC API
  • Choosing database drivers
  • Connecting to a database

Improving performance with prepared statements and stored procedures

  • Submitting SQL statements
  • Retrieving and processing results

7. Java Development Tools

  • Java Development Kit (JDK)
  • Compiler (javac)
  • Javadoc utility
  • Java Archive (JAR) utility
  • Java Integrated Development Environments (IDEs)
