They process this input data and write it to an output device or network. Java has around 50 keywords which are basics to java: abstractĬomputer programs read data from input devices like keyboard, mouse etc. We can only use them as the name of variables in Java, class, or method. We cannot use them in the rest of the programs. Keywords are the special words that are basically reserved keywords in any programming language. These components together help you to build Java programs.
#JAVA TUTORIAL GENERATOR#
compiler, an archiver (jar), and a documentation generator (Javadoc). JDK, along with the JRE, contains other resources like the interpreter, loader. There are Development Tools in JDK to provide an environment to develop Java programs. Java Development Kit provides an environment that helps to develop and execute the Java program. These tools together allow the development of applications and provide a runtime environment. Java Virtual Machine provides a runtime environment in which we can execute the bytecode. The following are some application areas in which we find Java usable: Multi-threaded: Java is a multi-threaded language as it can handle more than one job at a time. EJB(Enterprise Java Beans) and RMI(Remote Method Invocation) of Java are used to create a distributed system.ĩ. This is because Java supports TCP/IP protocol. Java works very well in the distributed environment of the Internet. Distributed: Java is a distributed language as it provides networking facilities. High Performance: Java provides high performance with the use of the Just-In-Time (JIT) compiler.Ĩ.

Java provides predefined information for everything related to storage, such as the size of primitive data types.ħ. There are no implementation-dependent features in Java. Portable: We can carry the bytecode of Java to any platform.
#JAVA TUTORIAL CODE#
The compiled byte code is platform-independent, and we can run it on any machine irrespective of the Operating system.Ħ. Platform-Independent: Java provides a guarantee that to write code once and run it anywhere(at any platform). Moreover, Java contains a security manager that defines the access levels of Java classes.ĥ. All Java programs run in the virtual machine. Secure: Java is a secure language, as Java does not use explicit pointers. Features like Exception handling and garbage collection make Java robust or strong.Ĥ. Java uses a garbage collector to provide a strong memory management system. Robust: Java always tries to check errors at runtime and compile time. A Java program must have at least one class and object.ģ. In other words, it has some data and behavior. Object-Oriented: Everything in Java is in the form of the object.

For example, the use of explicit pointers and operator overloading are not in Java.Ģ. Java eliminates many complex and ambiguous concepts of C++. Simple: Java is simple because its syntax is simple and easy to understand. Java Micro Edition (ME): We use this edition to develop applications for small devices such as set-top boxes, phones, and appliances, etc. Java Enterprise Edition (EE): We use this edition to create large programs that run on the server and to manage heavy traffic and complex transactions.ģ. Java Standard Editions (SE): We use this edition to create programs for a desktop computer.Ģ. Each Java edition has different capabilities. Java follows the WORA (Write Once, Run Anywhere) principle, and is platform-independent. Java is freely accessible to users, and we can run it on all the platforms. It is designed for the distributed environment of the Internet. Java is the most widely used programming language. In 2009, Oracle Corporation took over Sun Microsystem. Sun Microsystem changed the name to Java in 1995. It was developed by James Gosling at Sun Microsystems in 1991. Java programming language is a high-level, object-oriented, general-purpose, and secure programming language.
