CODSTA.LONG

Use `L' instead of `l' to express "long" integer constants

Description

This rule flags code where a long integer constant is indicated by `l' instead of by `L'.

Integer constants are "long" if they end in `L' or `l';. `L' is preferred over `l' because `l' (lowercase `L') can easily be confused with `1' (the number one).

Example

 package CODSTA;
 
 class LONG {
     long getLongNumber () {
         long temp = 23434l; // Is this 23434L or 234341?
         return temp;
     }
 }

Repair

 class LONG {
     long getLongNumber () {
         long temp = 23434L;
         return temp;
     }
 }
