JAVA

[learvy]

class helloWorld
{
public static void main(String args[ ])
{
System.out.println(“Hello World!”);
}

}


OUTPUT:

Hello World!


class - notifies the interpreter that a new class will be defined.
helloWorld - is the unique name for this new class.
{ } - signals the beginning and end of the class body.
public -is known as a 'global', a signal to the interpreter that this method can be used in other parts of the program. The private keyword prevents the rest of the program from calling anything inside a method.
static - tells the interpreter that the main method applies to everything in the helloWorld class, rather than just one element. Breathing and daily activities work as analogies for static and instance methods; daily activities vary but breathing is required.
void indicates that this method finishes operating without returning any results.
main - is the unique identifier for this method and is a reserved word because all Java applications have one and only one main method.
( ) - indicate that parameters can be passed to this method.

Java programming language is usually used to create Games. Though the earlier versions of Java is hard-coding. Yes, it's an object oriented language(OOP) but unlike other OOP's like Visual Basic Programming Languages, it doesn't have GUI. I don't know if the newer version of JAVA has GUI but the old version needs to have hard codes for you to create a simple text-box,label,button, etc.

How tough is it going to be if i am thinking of learning java on my own? Actually i am just familier with C++ and don't have any knowledge about java. So going through books and online materials will it help me make any progress? Or do you recommend me to join any java clases rather than going on my own?

if you are familiar with c or c++, then it will be a big help for you to understand java easier. They're logic is just the same, but they only differs in codes. And yeah, you really need to take java programming classes to help you out.

Before starting the clases if i want to learn something about Java on my own then how do you suggest me to proceed? Should i be following the materials available on the internet or would it be better to follow some specific book? As a beginner i do not want to feel that learning java is going to be tough so please do suggest me some easy and effective way to start it on my own.

we know that java Java is a programming language originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released.its logic is just the same, but they only differs in codes. And yeah, you really need to take java programming classes to help you out.

Suppose i wrote a program coding in c++ and now i need it in java coding. Then is there any provision of direct cpp codes in java? Or is the only option is to re code my programming in java from the very beginning?

i think java is a one kinds of social networking and programming language originally.it is use in many places .Though the earlier versions of Java is hard-coding. Yes, it's an object oriented language(OOP) but unlike other OOP's like Visual Basic Programming Languages, it doesn't have GUI

OK is shall think about taking the classes if it seem needy. Doing a programming which requires more graphics output, do you suggest to use java for such kind of programming?

Java is a programming language originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities than either C or C++. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture.

Java is really very important to create any type of software and it has great demand in market .To learn JAVA we should have knowledge of c ,c++ . And recently i am learning JAVA and i found it is really difficult to learn JAVA .

The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities than either C or C++. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java is as of 2012 one of the most popular programming languages in use, particularly for client-server web applications, with a reported 10 million users.[9][10]
The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java and GNU Classpath.

JAVA can be said as a pure object oriented programming language because it has all the features of object oriented programming language like polymorphism, inheritance, encapsulation, class, etc.
