Kathryn shows you how to import internal Java packages and libraries in order to get access to classes and functions that are already implemented.
- Libraries provide you with extra classes and methods…that are already implemented that you can use.…Some of the most well known internal Java libraries…are Java.lang, Java.util, and Java.net.…The Java.lang library package contains…the classes and interfaces that are…fundamental to the core Java language.…Some classes from this library are Boolean,…Byte, Float, Math, Process and Minimore.…The Java.util library provides users…with generic Java utilities, like scanning,…formatting strings, array manipulation utilities and more.…
Some classes and interfaces from Java.util include…Timezone, Hashtable, Vector,…Enumeration, and StringTokenizer.…The Java.net library contains classes in interfaces…that provide a powerful infrastructure…for networking in Java.…You can use classes in this library…to make API calls to retrieve data for your program.…Now that we know some of the libraries within Java,…let's try importing them and using them in our code.…To start off, we'll use the Pal class method…from the math class in the Java.lang library.…
