Re: Strings...immutable?

I couldn't tell ya, but it *is* the general case in Java. Most objects
will behave as you describe. Strings are special, although any object
could have this behavior if it wanted.

Here's maybe where you got the idea, perhaps from a poorly thought-out
example that exhibits the kind of behavior your are describing.

package stringtest;
public class Main
{
     public static void main(String[] args)
     {
    StringBuffer s = new StringBuffer( "hello" );
    StringBuffer t = s;
    System.out.println( s + " " + t );
    t.append( " good-bye");
    System.out.println( s + " " + t);
     }
}

init:
deps-jar:
compile:
hello hello
hello good-bye hello good-bye
debug:
BUILD SUCCESSFUL (total time: 1 second)

So there's the behavior, but it's from a StringBuffer, not a String.
Big difference there. But the difference between a StringBuffer and a
String might not be really easy for someone new to distinguish.
