CODSTA.USN

Use symbolic names for constants

Description

This rule flags code that uses an unnamed constant.

Named constants (final static variables) make the code much easier to understand and maintain. To avoid reporting too many spurious errors, Jtest will not report an error for the following integer constants:

-1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Jtest will only give one error per constant found in the code.

Example

 package CODSTA;
 
 class USN {
     private int[] getArray () {
         return new int [1000];
     } 
 }

Repair

 class USN {
     private int[] getArray () {
         return new int [ARRAY_SIZE];
     } 
     private static final int ARRAY_SIZE = 1000;
 }
