Q. In an object-oriented language such as Java, if I use a class that is GPL'ed without modifying, and subclass it, in what way does the GPL affect the larger program?

A. Subclassing is creating a derivative work. Therefore, the terms of the GPL affect the whole program where you create a subclass of a GPL'ed class.

How to use 

Option[] options = new Option[] {
    //           long option     argument type          short   description
    new Option("long-option1", "1", Option.REQUIRED_ARGUMENT, "description1"), 
    new Option("long-option2", "2", Option.OPTIONAL_ARGUMENT, "description2"), 
    new Option("long-option3", "3", Option.NO_ARGUMENT,       "description3"), 
};
Args arg = new Args(args, options);
Option[] parsedOptions = arg.getOptions();
for(int i = 0; i < parsedOptions.length; i++){
    System.out.println("arg" + i + ": " + parsedOptions[i]);
}

Above program execute result is follow. 

$ java Prog --long-option1=value1 --long-otion2=value2 --long-option2 -3 hoge
arg1:    -1, --long-option1: value1[REQUIRE ARGUMENT]
arg2:    -2, --long-option2: value2[OPTIONAL_ARGUMENT]
arg3:    -2, --long-option2: [OPTIONAL_ARGUMENT]
arg4:    -3, --long-option3: [NO_ARGUMENT]
