by oracle after a $7.4 billion acquisition. It was originally designed to have as few implementation dependencies as possible, hence the term “wora” which stands for “write once, run anywhere”. This means that the code that java compiles can run on any platform without recompiling the code. Java is known for its efficient processing speed in software, computer games and applications for both desktop and mobile devices. Hence it is used to develop software and web-based applications for various platforms.
Advantages and disadvantages of java
there are many advantages to using java as a programming language, including: – simple : java is an easy to learn and easy to understand programming language. In addition, java also eliminates all the complex features of c and c++ such as pointers, structures, links and makes code implementation easier. – object oriented (oop) : one of the main advantages of java is that it is an object oriented programming language. We all know that procedural programming languages are very complex and difficult to implement.
Obviously the use of oop concept
makes java easier to implement and much safer. It also helps in maintaining large chunks of code by dividing them into smaller named chunks. – security : languages like c and c++ use pointers, which allow access to memory locations. This is a security risk as pointers can lead to unauthorized access to memory. Sun microsystems has removed this feature in java making it a good security language. In addition, java also uses oop concepts like encapsulation, abstraction, inheritance which increase security and prevent unauthorized access by users.
Platform independent : java follows
the feature of “wora” (write once, run anywhere). Java programs written in one system can run on any other system that has java in it. Java compatibility is independent of operating system or hardware, which makes java platform independent and super flexible. – supports zalo database portability : java is a highly portable language. This is because java is platform independent and does not require any special hardware to run. This makes java compatible with almost every possible device. – supports automatic garbage collection : in c or c++, programmers have to free up space through the program.
In java, jvm automatically manages memory
Whenever there is an object that does not reference any class and needs to be dereferenced, jvm automatically removes them from the program, so programmers do not need to write any additional code. – multithreading support : thread is the smallest unit of a process. To achieve there are different types of testing you can maximum cpu utilization, multithreading is an important component. Java is a programming language that supports multithreading.
Stability : java receives regular
updates to remove bugs. This makes java one of the most stable programming languages available. Almost all bugs are immediately removed through updates. That is why it is very important to update java regularly. Provides efficient memory allocation strategy : java divides memory loan data mainly into two parts: heap area and stack area. Jvm allocates memory from either part depending on the requirement. This helps in efficient memory management. – large community support : java has been around for a long time, so it has built.
