Converting Integer to Long

Question

I need to get the value of a field using reflection. It so happens that I am not always sure what the datatype of the field is. For that, and to avoid some code duplication

Answer 1

Converting Integer to Long Very Simple and many ways to converting that
Example 1

 new Long(your_integer);

Example 2

Long.valueOf(your_integer); 

Example 3

Long a = 12345L;

Example 4
If you already have the int typed as an Integer you can do this:

Integer y = 12;
long x = y.longValue();
