Learning Java is a thorny and complicated path, and many students, unable to cope with the workload, seek Java homework help from services like Getcodinghelp.com. In this article, we’ll find out why it’s hard for students to learn this programming language, its main advantages and disadvantages, and how to make learning it as easy as possible.
What is Java used for?
As a general-purpose language, Java has gained fame and a wide range of uses:
- development of the server part of web applications (BackEnd);
- enterprise solutions for business;
- Android software development (Java is one of the main Android coding languages);
- banking systems;
- integrated systems and the Internet of Things (IoT);
- testing of the software;
- desktop applications;
- cloud data storage;
- programs for Big Data;
- software for manufacturing;
- computer games;
- other types of software.
As you can see, Java is a real El Dorado for beginners in terms of career perspective.

Pros and cons of Java
Anyone who starts learning Java from scratch should be aware of its robust set of advantages.
Pros of Java
- Platform-independence. Java applications can be launched practically on any device and platform where the Java environment is installed. Consequently, the range of use of this language expands. The combination of simple syntax and cross-platform makes Java a favorite of many developers, who know only one language and can program virtually anything with its help.
- A high-level programming language based on OOP principles. A highly correlated language means that the syntax is more accessible and transparent for programmers. Object-oriented programming makes the coding process user-friendly for people because many OOP mechanisms are intuitively understandable, and it is easy to find their analogs in everyday life. This is a good sign not only for the developer’s productivity but also contributes to a competent architecture of the code, its readability, support, and scalability.
- Strong performance indicators. You can not manipulate your storage with Java as skillfully as you do with C/C++, but most applications do not require such a masterly approach. Moreover, the built-in Java mechanisms (e.g., automatic storage management) and the JIT compiler sufficiently cover such needs and contribute to the optimization of the developed applications. An important role is also played by the literacy of the programmer who creates the software in Java.
- Programs written in Java are characterized by high reliability. Being a statically type-based language, Java rechecks the code for errors before execution, allowing to identify problem areas before the written program is launched.
- Security is a crucial criterion for working in a distributed and merged environment. The Java platform has strong protection mechanisms, with which it is important to attack intruders. For example, the ability to use digitally signed classes, the ability to use the Security Manager to set up access rights, etc.
- Convenient work with the network environment. Java is a good tool for network development, which allows you to work in this segment, just like in the usual local file system. Also, Java has a useful library for working with different protocols (HTTP, FTP, TCP/IP, and others).
- Great ecosystem. Java has accumulated many libraries and frameworks that have been tested and verified in working conditions during its lifetime. By choosing Java and additional Java-oriented technologies, you choose tools with high trust and reliability.
Cons of Java
Of course, Java is not perfect. Otherwise, it would not have had to compete for the top position with other languages. The disadvantages are as follows.
- Paid commercial use. Starting in 2019, the Oracle executives have changed the licensing policy, and all collections released after the new policy takes effect are free only if you use them for your own needs. But for using them for commercial purposes, you will need to pay by signing a paid subscription to Oracle.
- The low productivity in relation to C/C++ and low-core languages. Every high-level language cannot boast of high productivity because this is the flip side of the medal. The more laconic and humanly comprehensible a language is, the more resources it consumes — through compilation and abstraction using a virtual machine. Also, Java may be slowed down by an inbuilt app for storage cleaning, non-rational caching, and mutual blocking of threads. However, a literate approach to writing programs in Java will help to avoid all of these problems.
- Lack of good tools for creating complex and well-designed graphical interface (GUI). Although Java has enough frameworks for GUI creation (JavaFX, Swing, SWT, and others), none of them can provide a wide range of tools “for any taste or color.”
How to learn Java quickly
What is the right way to learn Java so that this process will bring a satisfying result and not a lot of nerves? This is very important when you study any programming language. To make learning Java as quick and efficient as possible, you should follow specific rules.
First, if you want to learn Java from scratch, you must dedicate a lot of time to it. How to learn Java quickly? Eight hours a day of theory and practice is the most productive investment. Of course, people with such strong motivation and who can allow themselves such a demanding schedule and way of life can be outnumbered on the fingers of one hand. So a simplified mode is suitable for the majority: 2 to 3 hours daily. If it is possible to allocate more time — do more because the more you contribute to programming, the sooner you get the desired results.
Remember that you should first find suitable training materials. Google and the responses of programmers will also help you.
Second, get information from a variety of sources. Every web service, every book, and article explains the same subject in its way. If you don’t understand something, look for an explanation in another source, but don’t abandon the topic because you didn’t understand it the first time. Maybe, the following reference in google will resolve all the issues.
Thirdly, having a knowledgeable mentor will help keep you motivated and make learning easier. You will become a fellow Java Jedi, which means your training will be more exciting and productive.
