Summary

• Representation of numbers in Java: the primitive numeric data types int, long, short, byte, float, double
• Set of values that can be represented, and operations on such primitive numeric data types
• Difference between the assignment for primitive data types and the assignment of references to objects
• Operators obtained by composition and expressions with side-effect
• Definition of constants
• Precision in the representation
• Conversion of strings in numbers and viceversa; input and output of numeric values
• Compatibility among primitive numeric data types; type conversions (cast)
• Other primitive data types in Java: char and boolean
