Hey!
Mahesh, even easier than that he can do this:
public class test
{
public static void main(String args[])
{
String[] str1 = { "AAAAAAA" }; // reference to the string array is
passed
method1(str1);
System.out.println("After returning from str1: " + str1[0]);
}
static void method1(String[] str1)
{
// now you can do anything you want to the string(s)
System.out.println("str1[0]: " + str1[0]);
str1[0] = "xxxxxx";
}
} // End of test
Dawg gonit. I didn't want to reply to this off topic posting. I promise I
won't
anymore. Let get back to servlets.
Sans adieu,
Danny Rubis
