Wrapper Classes - getxxx() Question

[Chris Gastin]

All wrapper classes have their particular getXxx() - I do not quite follow the API for it. For example could someone explain to me what getInteger() does?
Thanks

Welcome to the Ranch.
The porperties are name-value pairs that can be accessed with the methods getProperties() and getProperty() from the class System.
You can read about the class java.util.Properies in the Java Tutorial

Very simple example of use of Integer.getInteger:

public class A {
public static void main(String[] args) {
System.setProperty("Universal Number", "42");
System.out.println(Integer.getInteger("Universal Number"));
}
}
