Objectives

• Write Java code that uses variables, arrays, conditional and loop constructs
• Manipulate primitive numeric data and string data using Java operators
• Create Java classes and use object references
• Access the fields and methods of an object
• Manipulate text data using the methods of the String and StringBuilder classes
• Use casting without losing precision or causing errors
• Declare, override, and invoke methods

• Use classes from the java.time and java.time.format packages to format and print the local date and time
• Encapsulate a class using access modifiers and overloaded constructors
• Define and implement a simple class hierarchy
