java - Iterating through method parameters

It's a simple and maybe trivial question: in Java how can I iterate through the parameters passed to the method where I'm working?

I need it to trim() all of them that are strings.

EDIT

To be more precise an example of use can be this (written in a pseudo-code reflecting how I wish it to work):

public void methodName(String arg1, int arg2, int arg3, String arg4, double arg5)
    for(Object obj : getThisMethod().getParameters() )
        System.out.println(obj.getName() + " = " + obj.toString())

The point is that getThisMethod().getParameters(). What must I write in that place?

If your function uses Varargs this is pretty straightforward:

private void yourFunction(String... parameters) {
  for (String parameter : parameters) {
    // Do something with parameter
  }
}
