Hello Friends I am Kushal Bhatt. And I am welcome you on our blog CompuTech with another topic. Today's topic is Differ ence between C and Java ,C++ and Java. First we discuss Difference bet ween C and Java. 1 . C was develop by Dennie Ritchie at AT&T Bell Labs between 1969 to 1973, On other hand Java was develop by James Gosling at sun Microsystems which first appear in 1995. 2. C is Procedural Ori ented Programming langu age On other hand Java is Object Oriented Programming language . 3. C is Low level langu age On other hand Java is High level lang uage. 4. C is Compi le lang uage On other hand Java is Interpreter Langua ge. 5. C follow Top Bottom approach. on other hand Java follow Bottom Top approach. 6. C contains the Preprocessor Directives header file like #include,#define. On other hand Java not contains any header file. 7 . C support Goto statement, Structure,union but Java not support Goto statement, Stru...

Hello Friends I am Kushal Bhatt. And I am here with new topic on object oriented concepts on our blog CompuTech. So let's start our today's topic, Object oriented concepts are relates to our life Oops concept are used in real time use . It is also provide data hiding so data can not accessible by external functions. data abstraction concept that help in improve the security. In Object Oriented Programming program are divide in no.  of objects. New data and methods can easily add whenever necessary. Object oriented programming is follow bottom to up in program design. There are following concepts are providing by Object Oriented Programming. 1.class 2.Objects 3.Data Abstraction 4.Encapsulation 5.Inheritance 6.Polymorphism. 7.Message Communication 8.Data Binding . 1. Class :-          Class is a a way to enclose a methods variables in single package or unit known class. ...

Hello Friends I am Kushal Bhatt And here I am with new topic on our blog CompuTech. Today's topic is on JRE and JDK. So lets start our topic, What is JRE.? JRE stands for Java Runtime Environment. JRE is used to provide an runtime environment for java application. JRE is also consist a JVM and also implementing JVM whenever it requiring. JRE is provide all java classes and methods and other libraries ,Development tools to java applications. Without JRE you java application can not be run. It provide only runtime environment to java application not development application . Example if you want to make client only use java application not modification then you need to only install JRE to client machine . Which make enable only run java application. If you want to develop a java application then you need to install JDK on machine. JRE consist only JVM and Java Standard Libraries( JSL ). for Development JDK is used, JDK stands for Java Development ...

Hello friends I am Kushal Bhatt And I am welcome you on my another content on our blog CompuTech . In this blog we are discuss on JVM and JRE. So lets start our today's topic. It's not necessary to know internal works of JVM and it not having connection to java code programming but if you want to make deep knowledge related to java then you can find it here and it can be helpful to solve a problem which is unsolvable. 1 . What is JVM.? JVM stands for Java Virtual Machine. It is also called a Abstract Computer or Virtual Computer. JVM us essential part of Java. Normally all language compiler are translate source code to machine code for a specific computer . Java compiler is also done those things with slightly different way. You are already know the java is both compiler and interpreter language. So once java compiler convert your source code to not machine code  but it convert into byte code. This byte code are not understandable by computer as well ...
