Java programming for Begineers

Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere  meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages.

It is owned by Oracle, and more than 3 billion devices run Java.

It is used for:

• Mobile applications (specially Android apps)

• Desktop applications

• Web applications

• Web servers and application servers

• Games

• Database connection

• And much, much more!

  Why Use Java?

  • Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.)

  • It is one of the most popular programming language in the world

  • It has a large demand in the current job market

  • It is easy to learn and simple to use

  • It is open-source and free

  • It is secure, fast and powerful

  • It has a huge community support (tens of millions of developers)

  • Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs

  • As Java is close to C++ and C#, it makes it easy for programmers to switch to Java or vice versa
