Java In Telugu,Introduction to java ,Prologue to Java programming

JAVA was created by Sun Microsystems Inc in 1991, later obtained by Oracle Corporation. It was created by James Gosling and Patrick Naughton. It is a basic programming language. Composing, ordering and troubleshooting a program is simple in java. It makes secluded projects and reusable code.

Java phrasing

Before we start learning Java, let's get acquainted with regular java terms.

Java Virtual Machine (JVM)

This is by and large alluded as JVM. Previously, we talk about JVM lets see the periods of program execution. Stages are as per the following: we compose the program, at that point we assemble the program and finally we run the program.

1) Writing of the program is obviously done by java developer like you and me.

2) Compilation of program is finished by javac compiler, javac is the essential java compiler incorporated into java improvement unit (JDK). It takes java program as information and produces java bytecode as yield.

3) In third stage, JVM executes the bytecode created by compiler. This is called program run stage.

Along these lines, since we comprehended that the essential capacity of JVM is to execute the bytecode delivered by compiler. Each working framework has diverse JVM, anyway the yield they produce after execution of bytecode is same over every single working framework. That is the reason we call java as stage free language.

bytecode

As talked about above, javac compiler of JDK gathers the java source code into bytecode with the goal that it very well may be executed by JVM. The bytecode is spared in a .class document by compiler.

Java Development Kit(JDK)

While clarifying JVM and bytecode, I have utilized the term JDK. We should examine about it. As the name proposes this is finished java advancement pack that incorporates JRE (Java Runtime Environment), compilers and different apparatuses like JavaDoc, Java debugger and so on.

So as to make, accumulate and run Java program you would require JDK introduced on your PC.

Java Runtime Environment(JRE)

JRE is a piece of JDK which implies that JDK incorporates JRE. When you have JRE introduced on your framework, you can run a java program anyway you won't have the option to arrange it. JRE incorporates JVM, program modules and applets support. When you just need to run a java program on your PC, you would just need JRE.
