You can do it like this:
import java.lang.*;
public class test
{
public static void main(String args[])
{
String str1 = "AAAAAA";
str1 = method1(str1);
System.out.println("After returning from str1:
" + str1);
}
static String method1(String str1)
{
System.out.println("str1: " + str1);
str1 = "xxxxxx";
return str1;
}
} // End of test
