What the MyName Class demonstrates

Java starts by finding and running the method named main

public static void main(String[] arg)

String name defines a variable (or field)

  Notice where it is declared: inside the class but outside any method.

The name variable is associated with MyName objects

  These are called instance variables

You assign values to variables

  A variable (also called a field) is given a value using

destination = source expression;

You call methods

object_reference.method_name();

You generate output

System.out.println( [ a string ] )

Java forces you to check for possible exceptions

try {
 ...
} catch ( ... ) {
 ...
}
