Hi all,

I have had some doubts when I saw the code below.

final int x = 5; final int y; y = 6; switch( 8 ){ case x:// Compile case y:// Don't compile }

Could someome explain me the difference between initializing x and y ??

I would like to undertand why the line "case y:" doesn't compile, I think this is related in the way how the variable was initialized?

Thanks in advance

Hi,

You are absolutely right.

Strings are immutable, you can't change string's content, like you can do with a StringBuffer or StringBuilder. But you can change the value of reference, so when you used "r1.setName("Bird");", you were changing the reference of the attribute name.

Cheers.
