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, 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).
Prerequisites
Required Prerequisite
Java SE: Programming I Ed 1
Цель курса:
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
