Beginning Java Application Development (JavaSE)

Beginning Java training course teaches aspiring Java programmers the skills they need to successfully write their first applications in Java.Note: This course is optimized for Java 1.7, 1.8, or later. Earlier versions can be taught on request.

JAVA TRAINING OBJECTIVES

All students will:

• Understand Java’s importance, uses, strengths and weaknesses
• Understand Java language basics
• Write, compile, and run Java programs
• Understand the Object Model and Object Oriented Programming
• Use classes, inheritance, polymorphism
• Create well designed classes and use them in your Java programs
• Use composition and delegation to create objects from other objects
• Use packages to organize code
• Understand interfaces, their importance, and their uses
• Use interfaces to implement abstraction
• Learn good Java coding style
• Create well-structured Java programs
• Compile and execute programs with the JDK development tools and with an Integrated Development Environment (IDE) of your choice
• Use the core Java libraries (java.lang, java.util)
• Use exceptions for error handling
• Understand the basics of using JDBC and JPA, and use them to access databases from Java
• Use the Java Collections Framework
• Be aware of, and use the new features of Java 8 (if using Java 1.8 or later), as well as important advanced features of earlier Java versions
• Use basic I/O streams (Optional)
