How does Java work? As explained earlier, Java is a multiple platform programming language. This means that it can be written for one OS and run on another. How is this possible? Java code is first written in a Java Development Kit, which are available for Windows, Linux, and macOS....
Scripting languages also tend to be loosely typed. This means that avariable's typeis not defined within the code, but is determined at runtime and depends on the variable's value. In addition, a variable's type can sometimes change during the script's execution. For example, the following...
This means it can be executed directly in a browser. Other languages, like C, C++, and Java, are compiled languages and need to be translated into machine code before they can be executed. It Uses Dynamic Typing Dynamic typing means variable types are associated with runtime values, not nam...

Using things such as scripts and infrastructure as code. Even walking around an office with a USB drive, manually installing software on computers. Manually deploying software is labor-intensive and doesn’t scale well. Automation makes it easier and more cost effective to ensure consistency when ...
(it is only distantly and indirectly related to Java, for example), nor is it a simplification of anything. It is, however, limited. You cannot write stand-alone applications in it, for example, and it has no built-in support for reading or writing files. Moreover, JavaScript scripts ...
Avoid configuration drift:Idempotenceis a term frequently associated with infrastructure as code. When an operation is idempotent, it means that it provides the same result each time you run it. If you choose tooling that uses idempotent operations, you can avoid configuration drift...
A session is a series of interactions that take place within a single connection between two communication endpoints. A web application does not require authentication for every click since, HTTP is stateless, which means designers need to automate tracking the state of multiple connections from the...
Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
This module is a collection of resource utilities and libraries that support other Hadoop modules. Also known as Hadoop Core, it includes multiple resources for automatic failure recovery, file-system-level and operating-system-level abstraction, Java Archive (JAR) files and scripts, plus more. ...
