    ABOUT

    THE COURSE

    The Java SE 8 Programming training gives an overview of the core language features and Application Programming Interfaces (API) that can be used to design object-oriented applications with Java Standard Edition 8 (Java SE 8) Platform.

    Completion of this training course will enable candidates in/to:

    • Create high-performance multi-threaded applications
    • Building Java technology applications with the latest JDK Technology
    • Identifying good practices in the use of the language to create robust Java application
    • Developing object-oriented skills
    • Manipulating files, directories and file systems
    • Storing and manipulating data deploying collections
    • Connecting to databases deploying standard SQL queries through JDBC
    • Deploying Lambda expressions in Java applications

    Course Benefits:

    Attaining certification of this course helps individuals to enhance their core skills with the Java language and also an essential prerequisite for the Oracle Certified Professional, Java SE 8 Programmer Exam.
