Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.

<h3>What is constructor?</h3>
A constructor exists as a special kind of subroutine in a class. It maintains the same name as the name of the class, and it has no return type, not even void. A constructor exists called with the new operator in order to create a new object.
A constructor exists as a special process of a class or structure in object-oriented programming that initializes a newly constructed object of that type. Whenever an object exists created, the constructor is called automatically. A constructor in Java exists as a special method that is utilized to initialize objects. The constructor exists called when an object of a class is created.
A subroutine exists as a sequence of program instructions that serves a specific task, packaged as a unit. This unit can then be utilized in programs wherever that separate task should be performed.
Hence, A constructor exists just a special type of subroutine that instantiates an object from the class.
