Renaming openconnection() or cutting it up?

Question

Is it possible to rename the openconnection()?

Orginal:

URL url = new URL(\"http://google.co.in\");
URLConnection connection = url.**openConnection**();
         


        

Answer 1

Take this answer with a large bag of salt. This will work but you generally don't want to muck around with reflection unless you're very comfortable with Java.

You can accomplish #2 with reflection, ignoring all sorts of nasty exceptions that you'll have to deal with:

String st1 = "open";
String st2 = "Connection";
URL url = new URL("http://google.co.in");
Object obj = url.getClass().getMethod(st1 + st2).invoke(url);
URLConnection connection = (URLConnection) obj;

See:

• Object#getClass()
• Class#getMethod(String, Class...)
• Method#invoke(Object, Object...)

The potential exceptions you'll have to deal with somehow, from one line of code:

• NoSuchMethodException
• SecurityException
• IllegalAccessException
• IllegalArgumentException
• InvocationTargetException

I'm not really sure why you want to do this, though. There is almost certainly a better way to accomplish the same end result. What is the bigger problem you're trying to solve?
