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.

You can convert int to String using Integer.
String strValue = "7777"; int intValue = Integer.parseInt(strValue); int intValue2 = new Integer(strValue).intValue();
Remember, those will throw
if the string doesn't contain a valid value.
And about convert int to String you can use String.
int intValue = 15; String strVal1 = String.valueOf(intValue);
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
Hope this help...
