The term algorithm is used in a variety of fields, including mathematics, computer programming, and linguistics. Its most well-accepted definition is something that consists of a finite list of instructions (which are well defined) that can be used to accomplish a task. Basically, when an algorithm is given some initial state, it will use the …
The ability to debug any modern programming language is a critical skill for programmers of all skill levels. Learning how to debug Java helps developers discover the causes of logic and non-trivial syntax errors that prevent proper execution of Java programs. The ability to step-through a Java program using a debugging environment provided by updated …
To delete an element from the list, first the pointers are set properly and then the memory occupied by the node to be deleted is deallocated (freed). Deletion in the list can take place at the following positions. At the beginning of the list At the end of the list After a given element Before …
A breadth first search traversal method, visits all the successors of a visited node before visiting any successor of any of its child nodes. This is a contradiction to depth first traversal method; which visits the successor of a visited node before visiting any of its brothers, i.e., children of the same parent. A depth …
In this method, a function fn() is applied to each key. The result of this function determines into which of the several sub-files the record is to be placed. The function should have the property that x <= y, fn (x) <= fn (y). Such a function is called order preserving. Thus all of the …
The JNI (Java Native Interface) is a layer of Java that permits code executing or running in the JVM (Java Virtual Machine) to invoke and to be called by native libraries and applications written in other languages. The JNI is most commonly used with the C++, C, and Assembly programming languages. Typically, code developers will …

The javascript:void(0) error is fairly unique, in that it is one of the few computer-based errors that can be encountered by users of any operating system. The error is thrown on web browsers with the end-user surfs to websites that are not fully compatible with the version of Internet browser being used or have a …
Binary operators can be overloaded in a similar manner as unary operators. We should note the following features of an operator function for a binary operator: It receives only one class type argument explicitly, in case of a member function. For a friend function, two class types are received as arguments. It returns a class …
