So You’ve Heard of ‘Static’

Statics must be judicially used. And that too very carefully. One must be very clear of the implementation and must have all the below mentioned points in mind.

Reasons why one shouldn’t use statics-

1. They are a permanent resident of the memory stack.

2. They are initialized when the container class initializes.

3. Since they remain forever, they easily lead to memory leaks.

If you must use statics, for certain very strong reasons. You must use it with final modifier.

Using with mutable objects may cause the following problems – 

1. Frequent memory leaks

2. Also, when working in a threaded environment, using mutable may result in peculiar results unless handled properly.
