More than 3 billion devices run Java. As our world becomes more digital, the number of smart devices that run Java is increasing exponentially. Java has moved beyond just computers. Cell phones, parking meters, public transportation passes, ATMs, credit cards, and TVs, to name a few, run Java. Java Certified Professionals are needed to program all these devices.
Well-trained, highly skilled Java professionals are in demand!
- Earning a Java Certification deepens your Java expertise; you’ll develop sought after skills that map directly to real-world jobs
- 10 Million Java developers worldwide. You’ll stand out from the pack by earning a certification that truly validates your Java expertise
- 97% of certified Java professionals say they benefit from knowledge they acquired while preparing to take their certification exams, according to Java Magazine
- 93% of hiring managers say IT certifications are beneficial and provide value to the company according to CompTIA.
The process of becoming Java certified broadens an individuals knowledge and deepens your skills through exposure to a wide array of important features, functions and tasks. As you prepare for these certification exams, you can work your way through hands-on exercises and labs using real Java code, which expands on your own capabilities as a Java developer.
This entry-level course is aimed at programmers who are new to Java and who need to learn its concepts, language constructs, and data types. The course is designed for programmers who will apply these language skills to develop programs using the latest major versions of the JDK.
Course Objectives
This course will enable participants to:
- Write Java code that uses variables, arrays, conditional and loop constructs of achieve program objectives
- Identify modular programming principles
- Access and create static fields and methods
- Encapsulate a class using access modifiers and overloaded constructors
- Manipulate numeric, text, and string data using appropriate Java operators
- Set environment variables to allow the Java compiler and runtime executables to function properly
- Create simple Java classes and use object references to access fields and methods in a class
- Demonstrate polymorphism by implementing a Java interface
- Handle a checked exception in a Java application
- Use a Predicate Lambda expression as the argument to a method
- Define and implement a simple class hierarchy that supports application requirements
