Calling a method of an object

Once the class has been instantiated as an object, and the object reference has been assigned to a variable, you can call a method of the Java object by using the variable as the prefix:
IMPORT JAVA java.util.regex.Pattern
IMPORT JAVA java.util.regex.Matcher
    DEFINE p Pattern
    DEFINE m Matcher
    LET p = java.util.regex.Pattern.compile("[a-z]+")
    LET m = p.matcher("abcdef")
    DISPLAY m.matches()

In this example, the last line of the MAIN module calls an object method that returns a boolean value that is converted to an INTEGER and displayed.
