First of all, an example is not a definition of the problem. You need to define the problem very accurately and formally, then, perhaps, it will be clear to yourself. Anyway, http://whathaveyoutried.com so far?

Solution 1

log each digit into an array, get the indices of the digits to be swapped from the array, and swap them using a temporary variable.

Solution 2

Like suggested use the string representation of the number, e.g.

Java

String s = String.valueOf(456239875);
s=s.replace('4','x');
s=s.replace('9','4');
s=s.replace('x','9');
int result = Integer.parseInt(s);
System.out.println(result);
