Importance of constant class
<p>If I put constant variable values directly in classes, its panic when this value get changes.
If i make a constant class to keep such constants it helps to do changes in one class only. But again I need to identify all the classes which are using these constants. Because recompilation is required.</p>

<p>then what is the need of separate constant class?
suggest me another way to manage constants, if better.</p>
