JAVA PROGRAMMER

9.1 Прочитай, переведи текст java programming language и ответь на вопросы:

1. What is a Java?

2. What is the main feature of Java?

3. What does “WORA” mean?

4. What are end-users used to run Java applications?

Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another.

One design goal of Java is portability, which means that programs written for the Java platform must run similarly on any combination of hardware and operating system with adequate runtime support. This is achieved by compiling the Java language code to an intermediate representation called Java byte code, instead of directly to architecture-specific machine code. Java byte code instructions are analogous to machine code, but they are intended to be executed by a virtual machine (VM) written specifically for the host hardware. End-users commonly use a Java Runtime Environment (JRE) installed on their own machine for standalone Java applications, or in a web browser for Java applets.

Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.
