How Do I Pass a String Array to the Constructor of Another Class?

[JiaPei Jen]

I have a String Array 'to':

       String[] to = srf.getSelectedEmailAddresses();

and I am trying to pass this String array to the constructor of another class; Address is an abstract class and I use the javax.mail.internet.InternetAddress class:

Address [ ] address = new InternetAddress( // what should I do here? );

[Ko Ko Naing]

You need to put in loop, then you will get an array of InternetAddresses... Like this...

Address [ ] address;
for(int i = 0 ; i < to.length(); i++)
   address[i] = new InternetAddress(to[i]);

Hope it helps...

Or am I misunderstanding you, since it's incredibly easy...

That will give you a NullPointerException...

NullPointerException is occured because you not init value size of array.

chage code like this

int len = to.length();
Address [ ] address = new Address[len];
for(int i = 0 ; i < len; i++)
   address[i] = new InternetAddress(to[i]);

This will help you.

It will fail to compile - (use of uninitialized local).
Therefore, it will not give you a NullPointerException.

Why code? Tony is saying that the code above with uninitialized array will not compile and so NullPointerException will *not* be thrown beacuse program cannot run.
