There are various different patterns and they can be divided into these patterns they are: -
► Fundamental design patterns
► Creational patterns
► Partitioning patterns
► Structural patterns
► Behavioral patterns
► Concurrency patterns
Delegation, Interface, Immutable, Proxy and marker interface are some of the sub divisions present in Fundamental interface.
Template method is the most common way of representing. Implementation of a method differs for files, sockets, pipes, strings, text entry widgets, etc. When template method is used logic of the entire class is modified. Missing logic can be called by abstract and concrete methods.
They are mostly used as concurrency control constructs. They adhere and support Sync interface and conform to acquire release protocol. It adheres to a set of permits initialized in a constructor. A semaphore can also be described on the basis of a metaphor.
Lock is known to be the safest and the basic message control mechanism used in object oriented mechanism. This is used to block the usage of methods while another method is in progress. The only safest way to use lock mechanism is to fully synchronized objects.
In a fully synchronized object all methods are synchronized. Encapsulation violations are generally neglected. Methods are finite which release locks. Even in the presence of exceptions state of the object is at the beginning and end of each method.
