Multi programming:It is the technique of running various programs at a time by using timesharing.It permits a computer to do various things at same instant. It creates logical parallelism.The notion of multiprogramming is that the operating system keeps various jobs in memory concurrently. The operating system chooses a job from the job pool and begins executing a job, when such job requires waiting for any I/O operations the CPU is switched to other job. Therefore the main idea is that the central processing unit is never idle.

Cascading if-else statement: A form of if-else statement in which all else-part (apart from the last) comprises of a further nested if-else statement. Employed to overcome the trouble of textual drift frequently related with nested if statements.
Bounded repetition: The Repetition where statements within a loop's body are executed a fixed number of times and the number of times is established whenever the loop began. There is no control structure in Java which guarantees the bounded repetition
Finite State Machines : A Finite State Machine (FSM) is one of the most suitable models for formal checks, especially for concurrent systems. However, FSMs can have problems with inheritance (the state model can change in derived classes) if state asp

Exception handler: It is a try statement which acts as an exception handler - a place where exception objects are dealt and caught with.
Stepwise refinement: It is a divide and conquer approach to the programming, in which a complicated problem is recursively divided into smaller, sub-problems and more manageable. This approach to program design is frequently employed with structured p
