Webtrackker is the best Java training institute in Noida. Java is a programming language platform and high-tech computing developed by Sun Microsystems in 1995. Since then, language has been updated with version 8.0 of Java SE is the latest version, which was released March 2014.
Java has gained enormous popularity since it appeared for the first time. Its rapid ascension and broad acceptance can be attributed to its design and programming features, particularly in its promise to write a program once and run it everywhere. Java was chosen as a programming language for network computers (NCs) and was perceived as a universal front for the enterprise database. As indicated in the Sun Microsystems’ Java White Paper: "Java is a simple, object oriented, distributed, interpreted, rugged, secure, architecturally neutral, portable, multithreaded, and dynamic.
Java is platform-independent.One of Java's main advantages is the ability to easily switch from one computer system to another. The ability to run the same program on many different systems is fundamental to World Wide Web, Java software and manages to be platform independent of both source and binary level.

Java is multithread programming easily integrates, while in other operating languages system-specific procedures must be called to enable multithreading. Because of its robustness, ease of use, platform functionality, and Java security features, it has become the language of choice for providing Internet solutions around the world.
Java is both dynamic and extensible. Java code is organized into modular units called object-oriented classes. Lessons are stored in separate files and are loaded only in the Java interpreter, if necessary. This means that an application can decide because it takes lessons and can load them when they need it. It also means that a program can expand dynamically to load classes needed to extend functionality.
The central part of the Java platform means that a Java application can dynamically expand through new loaded network classes. An application that uses these is features to keep you a monolithic code block. Instead, it is an interactive collection of independent software components. So Java is a new and powerful metaphor for designing application and development opportunities.
As I described earlier, Java programs are compiled into an intermediate handset known as byte codes rather than native machine language instructions. Java Virtual Machine executes a Java program to interpret portable byte code statements. This architecture means that the fastest Java programs of programs or scripts written in purely interpreted languages, but are usually slower than C and C ++ programs that are compiled in a native machine. Please note that although Java programs are compiled in bytecode, not all Java platforms implement interpreted byte codes. Efficiency are computationally intensive parts of the Java platform - such as string manipulation methods - implemented using native code machines.
Although the first Java versions have led to performance problems, the speed of Java VM has greatly improved with each new version. VM is highly tuned and optimized in many important ways. In addition, many implementations include a just-in-time compiler, the conversion of Java byte code for incoming machine instructions. Using advanced JIT compilers can run Java programs at speeds comparable to C ++ native C ++ application speeds.
Java is a portable interpreted language; Java programs run almost as fast as native C ++ programs, C non-portable and. Performance was a problem that prevented some programmers from using Java. Now with improvements in Java 1.2, they have no performance issues anymore. In fact, the winning combination of performance, more portability is a unique feature that can offer no other language.
