Java SE: Programming II

Improving knowledge and skills to:

• 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.

• Developers.
