javaclass.static_field read or write a static Java field new javaclass(...) create a new Java object
Each JavaClass object contains properties that have the same names as the public static fields and methods of the Java class it represents. These properties allow you to read and write the static fields of the class. Each JavaClass object has different properties; you can use a for/in loop to enumerate them for any given JavaClass object.
java.lang.System is a JavaClass object that represents the java.lang.System class in Java. You can read a static field of this class with code like the following:
var java_console = java.lang.System.out;
You can invoke a static method of this class with a line like this one:
var version = java.lang.System.getProperty("java.version");
Finally, the JavaClass object also allows you to create new Java objects like this:
var java_date = new java.lang.Date();
