Java is a high-level, object-oriented programming language, and one of the most popular programming languages in use today. It is well suited to both standalone and web application development and is designed to provide solutions to most of the problems faced by programmers.
Java Basics: In Depth provides a comprehensive look at the Java programming language. You will learn how to:
Use primitive data types, operators, and control flow statements
Create objects and use them with classes and methods
Construct programs that interact with users
Modify data structures to improve performance and scalability
Work with packages and libraries
Process files and directories
Create modular programs using inheritance, interfaces, polymorphism, abstract classes, generics, inner classes, exceptions, assertions, logging, serialization, annotations, concurrent programming.
Java is the most popular programming language on the planet. It’s everywhere. It’s used in every industry. It runs on every platform and it can even be embedded in devices. Java is the backbone of Android, providing the underlying architecture that makes Android applications work. Java is at the heart of Google search, Facebook gaming, and some of the largest financial institutions in the world.
I am going to teach you how to build a Java program, starting from the very beginning. This course assumes no prior experience, but it also gives you a solid understanding of intermediate and advanced Java topics such as object-oriented programming (OOP) principles (inheritance and abstraction) and data structures like lists and maps.
Java is a general-purpose 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 compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.
Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
Java is a programming language that produces software for multiple platforms. When a programmer writes a Java application, the compiled code (known as bytecode) runs on most operating systems (OS), including Windows, Linux and Mac OS. Java derives much of its syntax from C and C++ . It’s object-oriented, platform independent and easy to use.
Java has become indispensable to developers by enabling them to:
* Write software on one platform and run it on virtually any other platform
* Create programs to run within a web browser and web services
* Develop server-side applications for online forums, stores, polls, HTML forms processing, and more
* Build complex applications that can run fast
The Java language is a key pillar in Android , the world’s most widely used mobile platform. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.
In this tutorial series, you’ll become familiar with Java, the programming language used to develop Android applications. Our goal is to prepare those already familiar with one programming language, such as PHP or Objective-C , to become comfortable working with the Java programming language and dive into Android app development.
Java is a fast, secure and reliable language used for many games, devices and applications. It is one of the most popular programming languages in the world and has more developers than any other programming language.
Java is an object-oriented, class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology. Java developers are in high demand as it is used by millions of devices worldwide. It is one of the most popular programming languages in use particularly for client-server web applications.
Java is an object-oriented, class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology. Java developers are in high demand across a range of industries, making Java developer jobs the most sought-after positions in the programming field.
Java was designed to have the look and feel of the C++ programming language, but it is simpler to use than C++ and enforces an object-oriented programming model. Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. It can also be used to build a small application module or applet for use as part of a webpage. Applets make it possible for a web page user to interact with the page.
Some facts about Java:
Java was developed by James Gosling at Sun Microsystems Inc in 1995.
It took 18 months to develop the first working version.
The language was initially called Oak after an oak tree that stood outside Gosling’s office.
Later the project went by the name Green and was finally renamed Java, from Java coffee, said to be consumed in large quantities by the language’s creators.
The first public implementation was Java 1.0 in
Java is one of the most widely used programming languages today. Learn the basics of Java and understand how to write basic Java programs.
Java is a platform independent language. What it means is that you can run the same Java program on any operating system having JVM (Java Virtual Machine). Hence, being a platform independent language, Java has made it easy for developers to write code that could work on different platforms without needing any modification. This interoperability feature has given rise to many cross-platform applications and frameworks like J2EE, Spring, Hibernate which are based on Java.
Java is an object oriented programming language. The object oriented paradigm focuses more on the data rather than the code. In other words, we focus on what data we want to store rather than how we are going to store it. This approach helps in keeping our code clean and modular which results in high quality software development and maintenance.
