Course Overview

This is a second-level course for people learning the Java language. It rounds-out the topics that were taught in the previous course, Java SE: Programming I and provides the additional key skills needed by Java programmers. This course uses today's main Java version for its practices (currently Java 11).

Course Objectives

  • Create Java applications that leverage the object-oriented features of the Java language, such as encapsulation, inheritance, and polymorphism
  • Execute a Java application from the command line
  • Create applications that use the Java Collections framework
  • Search and filter collections using Lambda Expressions
  • Implement error-handling techniques using exception handling
  • Implement input/output (I/O) functionality to read from and write to data and text files
  • Manipulate files, directories and file systems using the JDK NIO.2 specification
  • Perform multiple operations on database tables, including creating, reading, updating and deleting using both JDBC and JPA technology
  • Use Lambda Expression concurrency features
  • Apply modular programming practices and services to applications
  • Create high-performing multi-threaded applications
