The exact same way you instantiate a class from any of the various Java libraries: by using the 'new' keyword.
i.e
MyClass A = new MyClass();
this forces the MyClass definition to run its Constructor method, and return an instance of object of type MyClass.
It's the same as importing any other class: import [package name].[class name];
if you have a computer to look this up...... you can go and find out your self
A class is basically a definition, and contains the object's code. An object is an instance of a class. For instance, there is one java.lang.String class, but you can instantiate any number of distinct java.lang.String objects (instances). While a class defines the instance variables than an object has, the instantiated object itself actually contains those variables. So to put it simply: An object is an instance of a class.
There are a few places that a person can get a Java Applet tutorial. There are classes a person can take as well as self taught books and tutorials that a person can find online.
