I was going through Java documentation, and I learned that methods in the Arrays class in Java are all static. I don't really understand the reason behind why they made it static.
For example, the following code violates the OO approach, because if I have a type, 'X', then all the methods which acts on it should be inside it:
int[] a = {34, 23, 12};
Arrays.sort(a);
It would be better if they have implemented the following way:
int[] a = {34, 23, 12};
a.sort();
Can anyone explain me a bit on this?
In Java there is no way to extend the functionally of an array. Arrays all inherit from Object but this gives very little. IMHO This is a deficiency of Java.
Instead, to add functionality for arrays, static utility methods are added to classes like Array and Arrays. These methods are static as they are not instance methods.
