Java SE Programming II

Java SE Programming II

Dauer: 5 Tage, Tageskurs
Kurssprache: deutsch, Unterrichtsmaterial überwiegend in englischer Sprache

This Java SE Programming II training covers the core language features and Application Programming Interfaces (API) you will use to design object-oriented applications with Java Standard Edition Platform. This is a second-level course for programmers learning the Java language. It rounds-out the topics that were taught in the previous course, Java SE: Programming I (former Java Fundamentals), and provides additional key skills for Java programmers, such as secure coding, modular programming, and database access. This course uses today's main Java version for its practices (currently Java 11).

Course Objectives:

  • Use Lambda Expression concurrency features
  • Apply modular programming practices and services to applications
  • Create high-performing multi-threaded applications
  • 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
