program in array to remove zeroes from a digit

Question

ex.5400207 o/p::: 5427

Answer 1

1. Convert integer to string using method String.valueOf( int) which will return a string value

2. Implement method replaceAll(“0”,””) which means replace all zeros with empty string

3. Now parse string value to integer using method Integer.parseInt(string) which will return a integer value

Basically you are just using a replaceAll(“0”,””) to find the 0's and replace them with nothing. You just need to put this out as a string first.
