I was looking through an old Java book from college, based on Java version 5. In it it lists some of the main Java classes including wrapped data types. Java has had over a quarter century of use and spread and continues to exist. I defend the OO paradigm simply because it allows software to be described as the existence of objects rather than code. The main classes mentioned in this pocket guide are:
Boolean
Byte
Character
Cloneable
Comparable
DecimalFormat
Double
Float
Integer
Iterator (an interface)
Long
Math (mostly used for its static methods)
NumberFormat
Object (all classes extend from this)
Random
Scanner
Serializable (interface)
Short
String
System
Long may these reign it could be said. How many are out there? Java pairs well with Cobol as something to replace it.
