I need to change string "7777" to integer 7777, and integer 15 to string "15".

I would appreciate if you can help.

Thanks in advance,

Well, the answer to both of your questions can be found in the Javadocs for the java.lang.Integer class.

You have posted the same question in your other thread.
It would be easy to follow if you post at only one place.

You should get your answers here

String to int
int i = Integer.parseInt("7777");

you can have it in a try catch block or check to make sure that the string is indeed a valid number.

Hi Sanjul,
You can convert int to String using Integer.

Remember, those will throw NumberFormatException if the string doesn't contain a valid value.

And about convert int to String you can use String.

Oh ya... now in J2SE 5.0, there is a new feature about convert between primitive data type and its wrapper class. It is Autoboxing/unboxing.
You can read at Autoboxing

Hope this help...
Correct me if I am wrong..
