int to String conversion

[Anandh Ramesh]

hi,

i have a variable of type "int". i want to convert it to a string. can anyone help me on how to do it?

any help is appreciated.

[Rahul Bhattacharjee]

int i = 3;
String str = new Integer(i).toString();

[Jaikiran Pai]

Other way to do this:

int i =3;
String stringValue = String.valueOf(i);

[Rahul Bhattacharjee]

Jaikiran Pai's way is more prefered than the way that I have mentioned.As with his code we are not creating any object ,rather using a static helper finction of String class.

Also, if the type of i changes (for example to a long), the line of code doing the conversion will not need to change.

There's a good article on String conversion here:

What if you have a huge number and you want to include the thousand separators. I believe that you can use a NumberFormatter object to do this conversion to a String, but I don't know how.

How about the method:

int i = 1;
String str = ""+i;

Can someone explain the difficents with above?

How about the method:
 
int i = 1;
String str = ""+i;

Dave Lenton, mentioned a link in his post earlier. Have a look at that, it answers your question.
