Java Introduction:
Java programming language was initially created by Sun Micro systems which was started by James Gosling and released in 1995 as core component of Sun 'Micro systems' Java stage (Java 1.0 [J2SE]).
The most recent arrival of the Java Standard Edition is Java SE 8. With the progression of Java and its widespread fame, multiple configurations were build to suite different sorts of stages. Ex: J2EE for Enterprise Applications, J2ME for Mobile Applications.
The new J2 versions were renamed as Java SE, Java EE and Java ME respectively. Java is ensured to be Write Once, Run Anywhere.
We are provide the best java online training in usa, uk and globally. This training will gives complete knowledge of java.

Tools required:
For performing the illustrations shown above, you will require a Pentium 200-MHz PC with at least 64 MB of RAM (128 MB of RAM suggested).
You additionally will require the following softwares:
- Linux 7.1 or Windows xp/7/8 operating system.
- Java JDK 8
- Microsoft Notepad or any other text editor
This will give the fundamental abilities to make GUI, systems administration, and Web applications utilizing Java.
Basic Syntax:
For performing the illustrations shown above, you will require a Pentium 200-MHz PC with at least 64 MB of RAM (128 MB of RAM suggested).
About Java programs, it is critical to remember the following points.
- Case Sensitivity - Java is case sensitivity, which implies identifier Hello and hi would have different significance in Java.
- Class Names - For all class names the main letter ought to be in Upper Case.
- On the off chance that few words are utilized to frame a name of the class, each internal word's first letter ought to be in Upper Case. Sample class MyFirstJavaClass
- Technique Names - All method names ought to begin with a Lower Case letter.
- On the off chance that few words are utilized to frame the name of the strategy, then each inward word's first letter ought to be in Upper Case. Sample public void myMethodName()
- Program File Name - Name of the program file should exactly coordinate the class name.At the point when saving the file, you ought to save it utilizing the class name (Remember Java is case sensitive) and attach ".java" to the end of the name (if the file name and the class name don't coordinate your project won't completed).
- Example: Assume "MyFirstJavaProgram" is the class name. At that point the file ought to be saved as "MyFirstJavaProgram.java"
- public static void main(String args[]) - Java program processing begins from the primary() technique which is a mandatory part of each Java program.
Advantages of java:
Here are rew advantages for java:
2.Java is object-oriented: This permits you to make particular programs and reusable code.
3.Java is platform independent: A standout amongest the most significant circumstances of Java is its capacity to move effortlessly starting with one PC to another. The capacity to run the same program on a wide range of frameworks is pivotal to World Wide Web programming, and Java succeeds at this by being stage free at both the source and paired levels.
4.Java is distributed: Java is intended to make appropriated figuring simple with the systems administration ability that is innately coordinated into it. Composing system programs in Java is similar to sending and getting information to and from a record.
5.Java is secure: Java considers security as a major aspect of its configuration. The Java dialect, compiler, mediator, and runtime environment were each created in view of security.
