 Top-Down and Bottom-up Approaches:


 Top-down approach is a programming style. It is the base of traditional procedural languages, in which design begins by specifying complex pieces and then dividing them repeatedly into smaller pieces. The result of this breakdown is that the components are very specific and it becomes easier to write programs. This is the exact opposite of the bottom-up approach which is common in object oriented languages such as C++ and Java. 



For writing a program using top-down approach we write the main procedure first. This main procedure contains names of all the major functions it will need. Then we look at these functions as individual procedure and the process is repeated again. These divided sub-procedures will eventually perform actions that are very simple and their coding can be done easily and concisely. When all the various sub-procedures have been coded, we have the complete solution.

Java Java is an object-oriented programming language that produces software for multiple platforms. When a programmer writes a Java application, the compiled code (known as bytecode) runs on most operating systems (OS), including Windows, Linux and Mac OS)  Java Uses   Java is used as the server-side language for most back-end development projects, including those involving big data and Android development. Java is also commonly used for desktop computing, other mobile computing, games, and numerical computing.

Buzzword in Java - thejavaconceptspart Buzzwords in Java The Feature of Java are also known as Java Buzzwords. A list of Most important features of Java language is given as below Simple Java is very easy to learn and it's syntax is simple, clean and easy to understand.There is no need to remove unreferenced objects because there is an Automatic Garbage Collection in Java. Object-oriented Java is an object oriented programming language. Everything in Java is an object. Basic concepts of OOPS are:- Object Class Inheritance Polymorphism Abstraction Encapsulation Portable Java is portable" refers to the SE version. It means that you can run java bytecode on any hardware that has a compliant JVM Platform Independent Java is platform independent because it is different from other language like c, c++ etc which can compiled into platform specific machine while

Java Naming Conventions - thejavaconceptspart

-
Java Naming Conventions Java Naming Conventions Java is strictly a case sensitive programming language, where is Java applications there is a separate Recognization for lower case letters and for Upper case letters. To use lower case letters and Upper case letters in Java applications, Java has given a set of conventions All classes names, abstract classes names, interface names must be started with upper case letters and the sub sequent letters must also be upper case letters Ex: String, StringBuffer, InputStreamReader All Java variables names must be started with lower case letters buts the subsequent symbols must be Upper case letters Example: in, out, err, pageContext, bodyContent All the Java method names must be started with lower case letters but the subsequent Symbols must be Upper Case letters.
