Introduction Java

java introduction

The Java programming language and environment is designed to solve a number of problems in modern programming practice. Java started as a part of a larger project to develop advanced software for consumer electronics. These devices are small, reliable, portable, distributed, real-time embedded systems. When we started the project we intended to use C++, but encountered a number of problems. Initially these were just compiler technology problems, but as time passed more problems emerged that were best solved by changing the language.
What Is Java?
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. 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.

Who Created Java?

In the early nineties, Java was created by a team led by James Gosling for Sun Microsystems. It was originally designed for use on digital mobile devices, such as cell phones. However, when Java 1.0 was released to the public in 1996, its main focus had shifted to use on the Internet. It provided more interactivity with users by giving developers a way to produce animated webpages . Over the years it has evolved as a successful language for use both on and off the Internet. A decade later, it’s still an extremely popular language with over 6.5million developers worldwide.

Why Choose Java?

Java was designed with a few key principles in mind:

  • Easy to Use: The fundamentals of Java came from a programming language called c++. Although c++ is a powerful language, it was felt to be too complex in its syntax, and inadequate for all 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. Once data and its manipulation were packaged together in one place, it increased Java’s robustness.
  • Secure: 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 Independent: Programs needed to work regardless of the machine they were 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.
  • Editor(IDE): Java has many editors.They will help us to handle java GUI  easily.Some the Java IDE examples
  1. Eclipse: This is a very good and open source IDE. It is used a lot commercially and personally. It was made in Java so it’s cross-platform. It has a lot of support for additional plug-ins to extend your developing needs. What I love about Eclipse is that it compiles your code as you type. It highlights compiling errors and mistakes like how MS Word does for mis-spelled words.
  2. Net beans: This is a very good IDE also. It has a built-in GUI Builder for those you like that R.A.D. . It is used a lot commercially too. It was made in Java so it’s cross-platform like Eclipse.
  3. Blue J: This is an IDE developed towards first time Java developers. It teaches you a lot of programming concepts in Java and has a nice UML tool.
  4. J Creator: This is my first Java IDE I used. It is very good and very easy to use. This IDE was made in C++ unlike the ones above, which were all made in Java. Only runs on Windows platform.
  5. Intelligent Java IDEA: Intelligent IDEA is an intelligent Java IDE intensely focused on developer productivity that provides a robust combination of enhanced development tools.
  6. Borland J Builder: This is a great commerial IDE for Java. It does have a price but some developers believe it’s worth it. It also has a built-in Java GUI Builder.
  7. Dr. Java: Dr. Java is a lightweight development environment for writing Java programs. It is designed primarily for students, providing an intuitive interface and the ability to interactively evaluate Java code. It also includes powerful features for more advanced users.

The team at Sun Microsystems were successful in combining these key principles, and Java’s popularity can be traced to it being a robust, secure, easy to use, and portable language.
