Code re-usability is one of the many benefits of object oriented programming.

For example, in Java if you need to perform email validation in different classes, rather than writing validation code in each class you can create email validation method in one class and then call that method from other classes. Now you have only one piece of code for email validation which is easy to maintain.

Sorting an array in Javascript is a snap.
You create an array and then call sort() method on that array. The Javascript sort() method sorts an array in lexicographical order. This method is very useful in sorting alphanumeric values of an array. However, sort() will not work if the array consists of numeric values. Because the alphabetical order of numbers is different from their numeric order the sorted array may not be in the order you are expecting. For example, in a dictionary sort the number “11″ would come before number “5″. This may not be the result that you are looking for.
Here is an example

var ages = new Array (23,6,2,16,48,9,6);
ages.sort();

The array will become (16,2,23,48,6,6,9)

Fortunately, the work around for this problem is quite simple.
