so why not instead of doing
void method1(String str)
you do
String method1(String str)?
have the method do
return "xxxxxx";
and you can have str1 sort of the way you want it
str1 = method1(str1);
You do have to be careful of multitthreading issues here though.

This is *WAY* off topic and I didn't want to answer this (but I did so be it)
