Boundary error: The errors which arise from programming mistakes prepared at the edges of a problem- indexing off the edge of an array, commencing with no items of data, loop termination and so forth. Boundary errors are a very general type of logical
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
Passing by address or reference: In this technique no separate memory build for formal variables that is, formal variables share similar location of actual variables and therefore any change on formal variables automatically reflected back to real var
Unconditional Jumps: Jumps which are not strictly upwards in the block hierarchy can require extensive control-flow manipulation, including creation of redundant code, and should be avoided if possible. Such jumps add considerable modeling overhead fo

Finally clause: This is a part of try statement which is always executed, either subsequent the handling of caught exception, and normal termination of the protected statements.
Inconsistent state: A state which an object must not be in. A class requires to be carefully designed in order to make sure that none of its examples can get into a conflicting state. An illustration of an inconsistent state may be a football team wit
Polymorphism: It is the ability of an object reference to be employed as if it referred to an object with various forms. The polymorphism in Java outcomes from both class inheritance and interface inheritance. The actually different forms frequently o
Out of scope: It is a variable is in scope as long as the program's flow of control is in the variable's defining block. Or else, this is out of scope.
Memory leak: It is a situation in which memory which is no longer being employed has not been returned to the pool of free memory. The garbage collector is designed to return unreferenced objects to the free memory pool in order to shun memory leaks.<
