Software Programming (Java)





What is a Programme,

Generaly a Programme is a sequence of instruction. Return in a Programming language to preform a specified task on a Computer.

What is a Programming Language,

Any notational system for discribing Algorithms and Data Structurs in both machine readable and human readable formand which can be inmplemented on a computer.


Problem Sloving steps

1.  Analysing a problem.
2.  Develop and Algorithms.
3.  Developing(writing) a computer.
4.  Language (coding)
5.  Check the solution.




Algorithms, Florchart and Programming Design

The sequene of steps to be performed in order to solve a problem by the computer is know as an “Algorithms”

“Flowchart” is a praphical or symbolic representation of an “Algorithms”. It is the diagrammatic representation of the step-by-step solution to a given problem.

“Program Design” consists of the steps a programmer should do before they start coding the program in a specific language. Proper program design helps other programmers to maintain the program in the future.



ALGORITHMS


Look around you. Computer and networks are everywhere, enabling an intricate web of complex human activities: education, commerce, entertainment, even war. Of the two main technological underpinnings of this amazing proliferation, one is the breathtaking pace with which advances in microelectronics and chip efficien algorithms that are fuelling the computer revolution.

In mathematics, computer science, and related subjects, an Algorithms is a finite sequence of steps expressed for solving a problem. An algorithms can be defined as “a process that performs some sequence of Operation in order to solve a given problem”. Algorithms are used for calculation, data processing, and many other fields.

In computing, algorithms are essential because they serve as the systematic procedures that computers require . A good algorithm is like using the right tool in the workshop. It does the job with the right amount of effort. Using the wrong algorithm or one that is not clearly define is like trying to cut a pice of plywood with a pair of scissors: althogh the job may get done, you have to wonder how effective you were in completing it.
