Advantages and Disadvantages of Java

On 18 Mar., 2021

The article discusses the advantages and disadvantages of Java. There are more advantages to Java than disadvantages. Apart from all the limitations mentioned above, Java is one of the most widely accepted words in the software application due to its program independence, assurance, and maintainability characteristics. In this article, you can easily compare Java with other languages based on its advantages and disadvantages.

Advantages and Disadvantages of Java

 

Java is a consistent rank at the top of the TIOBE index among all other programming languages. Despite the discovery of many new languages, Java's reputation never diminishes. Java has dominated all other languages for more than 20 years. Most experts cannot deny that Java is one of the most potent and efficient languages of all time and that it is the most widely used programming language in many fields.

 

However, we also know that every coin has two sides; similarly, Java cannot escape this fact. It has its limitations and advantages, which we call the advantages and disadvantages of Java. This article will present the significant advantages and disadvantages of Java, which will help you get a clear picture of this language.

Advantages of Java

Java is an object-oriented and general-purpose programming language that allows you to create programs and applications on any platform. Java has many advantages that will enable you to stick to it. 

Let's discuss the benefits of using the Java programming language.

 

1. Java is simple

Any language can consider simple if it is easy to learn and understand. Java syntax is simple, easy to write, easy to learn, maintain and understand and the code is easy to debug. Besides, Java is less complex than C and C++ because many of these languages' complex features get remove from Java, such as the concept of explicit pointers, storage classes, operand overloading, and more.

 

2. object-oriented programming language

Java is an object-oriented language, which increases the flexibility and reusability of the code. The OOP concept allows objects to reuse in other programs easily. It can also increase security by storing data and functions in one place and preventing outside access. It also organizes large modules into smaller ones, making them easier to follow.

 

3. Java is reliable

Java overcomes protection threats and opportunities by avoiding the use of explicit pointers. Pointers store memory addresses of other values, which can result in unauthorized memory access. This problem addresses by removing the concept of pointers. Besides, Java provides a security manager for each application to define access rules for classes.

 

4. Java is inexpensive and easy to maintain

Java programs are inexpensive to develop and maintain because they require a specific hardware infrastructure to run them. Can run it efficiently on any machine, which reduces additional maintenance costs.


 

5. Java is platform-independent

Java offers an exciting advantage to users by providing a platform-independent feature. Java-compiled code (bytecode) is platform-independent and can run the machine independently, regardless of the operating system. You can run the code on any device that supports the Java Virtual Machine (JVM), as shown in the figure below.

 

6 Java is a high-level programming language

Java is a high-level programming language because it is a human-readable language. It resembles a human language and has a simple and easy to maintain syntax, similar to the syntax of C++ but in a more detailed way.

 

7.Java supports a feature called portability.

Java is a portable language because it is platform-independent; Can run Java code on any platform. Because it is portable, it can be ported to and implemented on any platform. Therefore, Java also has the advantage of portability.

 

8.java provides automatic rubbish collection.

Java provides automatic memory management, which handles by the Java Virtual Machine (JVM), object use in a program for a long time, does not refer to anything, or is deleted by explicit programming. In Java, unused items are automatic get deleted by an automatic rubbish collection process.




 

9. Java supports multithreading

Java is a multithreaded language, i.e., in Java, it can execute more than one thread more than simultaneously. A thread is the most negligible unit of a process, helps us to gain maximum CPU utilization. Multiple lines share a shared memory area and increase the efficiency and performance of the application. These threads execute independently of each other without affecting each other.

10. Java is stable

Java programs are more stable compared to programs in other languages. Moreover, a new version of Java releases more advanced features in no time, making it more durable.

 

11. Java is reliable.

Java is a shared language as it presents a method for sharing data and programs between multiple computers that improve the system's performance and efficiency. Remote Method Invocation is something that supports distributed processing in Java. Besides, Java also supports Socket programming and CORBA technology to distribute objects in a dispersed situation.

 

12. Java presents an effective memory allocation strategy

Java provides an efficient memory allocation strategy as it divides the memory mainly into two parts- Heap Area and Stack Area. JVM gives us the memory area for each variable, either from the stack area or the heap area. Whenever we declare a variable, JVM allocates memory either from the stack area or the stack area.

 

Java disadvantages

To start learning or working with any programming language, you need to know its strengths and weaknesses to get the most out of it and avoid the conditions that show its shortcomings. Java also has a few drawbacks that you need to know before you start from scratch. Let's talk about the disadvantages of using Java.

 

1. Java is slow and has poor performance

Java consumes memory and is significantly slower than native languages like C or C++. Compared to other communications like C and C++, it is also slow because it must interpret every machine code. This sluggish performance is due to the additional compilation and abstraction performed by the JVM. In addition to this, sometimes the garbage collector in Java causes poor performance because it consumes more CPU time.

 

2. Java does not offer an attractive appearance and user interface feel.

Although Java has many GUI builders for GUI creation, they are not suitable for creating a complex user interface. There are many inconsistencies in their use. There are many popular frameworks for GUI creation, such as Swing, SWT, JavaFX, JSF. However, they are not mature enough to develop a complex GUI.

 

3. Java does not provide a backup facility

Java works mainly with storage and does not focus on backing up data which is a significant drawback that makes it lose interest and ratings.

 

4. Java requires significant memory space

Compared to other languages such as C and C++, Java requires significant or large amounts of memory. During the execution of garbage collection, this can affect memory efficiency and system performance.

 

5. Bulky and complex code

Java codes are lengthy, which means that they contain many words and many long and complex sentences that are difficult to read and understand, reducing the readability of the code. Java focuses on making it easier to use, but at the same time, it has to compromise this with overly complex code and lengthy explanations of everything.
