Java SE: Programming I Training in Hong Kong

It is recommended that you have previously studied programming languages, or have an existing knowledge of Java Programming.

• 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
