Pros and Cons of Java

Pros and Cons of Java

Java is one of the most popular technology in use today. It is a general-purpose programming which uses object-oriented paradigm to create programs that can run in any platform.

You can use it to run desktop, mobile and enterprise applications. Let’s have a look at the pros and cons of using this programming language.



1. Object-oriented programming (OOP): Java uses OOP concept which allows you to define the data structure, data type, and set a set of functions. Objects created can be manipulated and users can easily reuse these objects in other programs.

2. High-level language: It is a high-level language similar to human language making it easy and simple to write, read and maintain.

3. Cheap to maintain: Java program does not depend on any specific hardware infrastructure to run. You can easily run the server in any machine making it cheap to maintain.

4. More secure: Some Java features help to protect you from security flaws. Through the security manager feature, you can specify the access rights and rules. This helps reduce security risks.

5. Platform-independence/Portability: Java program is a write once run anywhere application which enables you to run the program in any platform that supports Java Virtual Machine (JVM) making it highly portable.

6. Stability: Programs built using Java application platform are more stable and a new version of Java is released each day with advanced features making it more stable.

7. Allocation: The Stack allocation system feature in the Java environment enables data storage and can also enable data to be restored easily.

8. Automatic memory management: You don’t have to worry about manual memory management task. The automatic memory management handles memory allocation and deallocation.

9. Multithreading: It enables other programs to perform several tasks simultaneously within the program.
There are also a lot of pre-made classes and standard library to create more user functions.

10. Efficiency: Java is a distributed language which can be integrated to share data and programs on multiple computers as well as improve the efficiency.


1. Look and feel: The look and feel of the default graphical user interface application written in Java are totally different from the standard native applications.

2. Memory requirement: Compared to other compiled programs like C and C++, Java consumes more memory and significantly slower in performance.

3. Inefficient architecture code: Java programming is very complex and the process of coming up with architectural code is inefficient. Once the bytecode is compiled, a Java virtual machine interpreter program has to run the code.

4. Limited option: It has limited latency-critical tuning option making it unsuitable if you want to spare every millisecond. You may prefer to use other programs for that.

5. Bugs in JVM implementation: Some bugs in the JVM environment limits Java’s usefulness although it is only on some Java Virtual Machines.

6. No generic programs: If you need Strongly Types Collections, you have to write them by yourself. Java does not support generic programming.

7. Multiple inheritance issues: It is impossible to use multiple inheritances in Java programming.

8. Paid commercial license: Starting 2019, you will have to pay to license for Java standard Edition8 for business, commercial and production. This will be an increased expense to companies that want to upgrade their services.

9. No back-up: Java works mainly for storage and not back up. This makes java lose its ratings and prestige due to inefficient backup.

10. Java is Slow: It is comparatively slow in speed compared to other programming languages since each program code has to be interpreted to machine-readable code.
