jpl.Integer
public class Integer
Integer is a specialised Term with a long field, representing a Prolog integer value.
Integer i = new Integer(1024);Once constructed, the value of an Integer instance cannot be altered. An Integer can be used (and re-used) as an argument of Compounds. Beware confusing jpl.Integer with java.lang.Integer.
