portability meaning in java

Porting is also the term used when a video game designed to run on one platform, be it an arcade, video game console, or personal computer, is converted to run on a different platform.From the beginning of video games through to the 1990s, "ports", at the time often known as "conversions", were often not true ports, but rather reworked versions of the games. Portability Meaning. Portability fails, however, to be perfect. Sign-up now. Using a common language, such as C, improves the chances of successfully porting a product from one machine to another. Or being transpiled to C/C++ with a supporting framework? Cookie Preferences There is a catch, however; just because an application is portable doesn't mean that is is capable of being integrated or is interoperable with other applications. As we know, one of the main strengths of Java is its portability – meaning that once we write and compile code, the result of this process is platform-independent bytecode. Java offers higher cross- functionality and portability as programs written in one platform can run across desktops, mobiles, embedded systems. Therefore, if database portability is a goal you should try to use only generic SQL type identifiers. Features of Java. portability definition: 1. the quality of being light and small enough to be easily carried or moved: 2. the quality of…. Java programming language, in effect, defined the concept of portability. But you’ll see portability talked about in the early days of C, and later with Java.” Nonetheless, Peterson said, if you look at the enterprises that standardized on Java, they also standardized on specific server platforms and specific operating systems and other specific technology. Portability in java means java programs can be run on any pc independant of hardware, OS where JVM (java virtual machine) is installed. The getConnection(String url) method of Java DriverManager class attempts to establish a connection to the database by using the given database URL. It aims to download programs to a wide variety of devices and have them produce the same results. Java Servlets enable developers to easily implement server-side behaviors that take full advantage of the power of the rich Java API. Being able to move software from one machine platform to another. But, what prevents a Java application from shipping within a JVM wrapper? This project was developed with Servlets, advanced java programming, oracle database server and JDBC connectivity. The points given below will briefly distinguish the differences between Portability and Compatibility. Simply put, this can run on any machine or device capable of running a Java Virtual Machine, and it will work as seamlessly as we could expect. When we compile a java program using command "javac filename.java" , a filename.class file is generated .This is known as byte code. As we know, one of the main strengths of Java is its portability – meaning that once we write and compile code, the result of this process is platform-independent bytecode. Start my free, unlimited access. =>Compatibility deals with whether two or more components can be run in the same environment at the same time without adversely affecting the behavior of each other. The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. See more. This feature makes java platform independant. A computer software application is considered portable to a new environment if the effort required to adapt it to the new environment is within reasonable limits. Do Not Sell My Personal Info. But, what prevents a Java application from shipping within a JVM wrapper? The Java Language Spec and VM Spec go to great lengths to make Java programs portable in this sense. adj. This point is most clearly seen when one thinks about .NET or Java applications. Portable computers include notebook and subnotebook computers, hand-held computers, palmtops, and PDAs. Capable of being transferred from one employer to another. It is a specification that provides runtime environment in which java bytecode can be executed. The appropriate driver from the set of registered JDBC drivers is selected. Recently, the Java programming language and runtime environment has made it possible to have programs that run on any operating system that supports the Java standard (from Sun Microsystems) without any porting work. Portability refers to an inherent property of the program, not the availability (beyond 2) of platforms. As a platform-independent environment, the Java platform can be a bit slower than native code. The two languages have different "portability" goals. Application portability is the ability of an application to be portably installed, deployed, accessed and managed - regardless of delivery model. (1) When used to describe hardware, portable means small and lightweight. In the case of Java, it is the magic of Bytecode that makes it platform independent. I plan to publish articles explaining how to use some of those new features from time to time, and this is the first such article. The amount of the estate tax exemption that was not used for the deceased spouse's estate can be transferred to the surviving spouse if the first spouse dies and the value of their estate doesn't use up all the exemption. Java is a mature language, therefore more stable and predictable. The Java programs executed by the JVM that makes the code portable and secure. Case Sensitivity − Java is case sensitive, which means identifier Hello and hello would have different meaning in Java. The Java Tutorials have been written for JDK 8. Once developed, that app can be used on any device and on any operating system. Portability testing refers to the testing with ease of moving one product or software from one environment to another. C# on the other hand is not a portable language even though strides have been made to improve its portability. Portability has usually meant some work when moving an application program to another operating system.
