Java is a computer programming language. It enables programmers to write computer instructions using English-based commands instead of having to write in numeric codes. best java training institute in noida .It’s known as a high-level language because it can be read and written easily by humans. Like English, Java has a set of rules that determine how the instructions are written. These rules are known as its syntax. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute.
Java is fast, secure, and reliable There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Features of Java
Ease of Use: The fundamentals of Java came from a programming language called C++. Although C++ is a powerful language, it is complex in its syntax and inadequate for some of Java's requirements. Java built on and improved the ideas of C++ to provide a programming language that was powerful and simple to use.
Reliability: Java needed to reduce the likelihood of fatal errors from programmer mistakes. With this in mind, object-oriented programming was introduced. When data and its manipulation were packaged together in one place, Java’s was robust.
Security: As Java was originally targeting mobile devices that would be exchanging data over networks, it was built to include a high level of security. Java is probably the most secure programming language to date.
Platform Independence: Programs need to work regardless of the machines it is being executed on. Java was written to be a portable language that doesn't care about the operating system or the hardware of the computer or device it is running on.
