Integer class has static method toString   - you can use it   int i   1234  String str   Integer toString i        Returns a String object representing the specified integer  The argument is converted to signed decimal representation and returned as a string  exactly as if the argument and radix 10 were given as arguments to the toString int  int  method

The way I know how to convert an integer into a string is by using the following code   Integer toString int     and   String valueOf int     If you had an integer i  and a string s  then the following would apply   int i  String s   Integer toString i   or String s   String valueOf i     If you wanted to convert a string  s  into an integer  i   then the following would work   i   Integer valueOf s  intValue

Always use either String valueOf number  or Integer toString number    Using      number is an overhead and does the following   StringBuilder sb   new StringBuilder    sb append      sb append number   return sb toString
