These tools ensure that Java applications can run securely and efficiently across different operating systems and hardware configurations, making Java a preferred choice for developers aiming for high cross-platform compatibility.

The Core of Java: Object-Oriented Programming

At its core, Java is an object-oriented programming (OOP) language, which means it is designed around the concept of objects rather than actions. This approach not only simplifies the software development process but also enhances the manageability and scalability of complex software systems. Object-oriented concepts such as inheritance, encapsulation, and polymorphism allow developers to create modular programs with reusable code, leading to more efficient and error-free software development.

Java in Web Applications

Java’s capabilities extend vigorously into web development, primarily through enterprise-level solutions via Java EE (Enterprise Edition). This platform provides an API and runtime environment for scripting and running enterprise software, including network applications and web services. Java EE supports many components of modern web applications, including Servlets, Java Server Pages (JSP), and Enterprise JavaBeans (EJB), which streamline the development process and enhance the functionality of web applications.

Advancing with Java: Frameworks and Libraries

The strength of Java also lies in its rich assortment of frameworks and libraries that simplify various aspects of application development. Frameworks like Spring, Hibernate, and Struts have become indispensable in the Java community, offering ready-to-use, high-performance components that solve common programming tasks. These frameworks not only speed up the development process but also promote best practices in Java programming.These frameworks support complex data handling, asynchronous programming, and ensure thread safety, making them ideal for developing high-throughput applications that require robustness and scalability.

Exception Handling and Debugging

Advanced Java programming also involves sophisticated techniques in exception handling and debugging, which are critical for building reliable and robust applications. Effective exception handling ensures that your application can gracefully handle unexpected situations without crashing, while advanced debugging techniques, such as using breakpoints, stack traces, and logging frameworks like Log4J or SLF4J, allow for pinpointing issues quickly and efficiently. These practices are essential for maintaining high-quality code and ensuring application stability and security.

By integrating these advanced techniques, Java developers can significantly enhance the functionality, performance, and reliability of their applications.

Below is how and why I chose NetBeans for myself and my team. Also discussed are a few other decent editors and IDEs for PHP that can be useful in certain circumstances: Vim, JEdit, Eclipse PDT, Komodo IDE.

Choosing an IDE for PHP

There used to be a standard answer to the question of which IDE to do a PHP project in – ZendStudio. Of course, it was paid, but you understand, it was not a problem for anyone:)

Unfortunately, Zend got tired of pulling the burden of developing the original IDE. The current version of ZendStudio is just Eclipse with the Zend logo and the PDT (PHP Development Tools) add-on. On the one hand, it is nice that you can download Eclipse and install this set of plugins for free. On the other hand, Eclipse turned out to be a voracious behemoth compared to the old ZendStudio. It requires more memory, more CPU and draws its glamorous windows much slower.

Many people will say – “It’s nothing like that, it’s not critical on any modern computer, and Eclipse works fine for me”. But for our company it is very critical. The fact is that in our firm, developers sit on thin clients (Sun Ray). In fact, they all work on the same computer. Project managers, CFO and admin also sit on it. A dozen and a half Firefox and a dozen OpenOffice applications are running simultaneously. In such an environment, running just two Eclipse instances leads to a noticeable slowdown for all users. And we need to launch about ten instances.

Of course, we know the recipe – buy a more powerful server. But it’s a shame to spend money, because ZendStudio worked perfectly well in this environment, while PDT has no new “magic” features compared to ZendStudio.

Another disadvantage of Eclipse PDT, which made us give up on it completely, is its inability to SSH using keys. In our company, access to virtual machines where projects are uploaded is done exclusively by keys. This completely solves such common problems as the problem of a fired programmer who forgot to change his password, the problem of a password written down on a piece of paper stuck on the monitor, the problem of a forgotten password and so on. Naturally, we have automated generation of the key and putting it on the virtual machine, and it saves admin’s time. Anyway, we were not going to give up access by public key just because Eclipse doesn’t know how to do it.

As a temporary solution, we switched to Vim. With the addition of a few plugins and tweaking of certain parameters, writing PHP in Vim is quite convenient. (There is an excellent article on turning Vim into a powerful PHP editor).

Naturally, you could forget about the system resource problem forever. A console editor in terms of memory and CPU consumption is just a holiday. But there were quite a few drawbacks in other areas.

First of all, Vim is not an IDE after all, but a text editor. It knows nothing about the fact that the text you are writing is a PHP program, it knows nothing about the fact that you store the source code in SVN. Accordingly, it is not as intelligent as a real IDE, ctags don’t always understand where a function or method is described. You have to constantly remember that after editing you still have to pour the files into SVN using console commands. The lack of a visual diff interface is noticeable. Each problem on its own is a small thing for a real hardcore programmer, but all together they noticeably reduce productivity.

Secondly, Vim is a very specific editor. You need to learn it. Only those who have already used Vi can understand the depth of this phrase:) Yes, in a couple of weeks a novice developer will learn all the commands that are needed in everyday work. But after all, those couple weeks could have been spent learning more necessary things, or just making money.

A side problem that grows out of the specificity of Vim is constant errors when switching to other programs. A developer periodically needs to write reports, use e-mail, i.e. edit texts in other text editors. As a result, before each action, the fingers freeze for a split second, and the brain frantically tries to understand what to press now – +s or :w. This is annoying and reduces productivity.

Appearance

You can customize the appearance or theme of the interface. By default, Eclipse is set to a light theme. You can change it to a dark theme by going to Preferences > General > Appearance > Dark.

Perspective

Because Eclipse is a cross-language IDE, you must have a gap between the languages you use. The IDE’s perspective feature configures the program to process code according to the syntax of a particular language. Since we are dealing with JAVA, you must set your perspective to JAVA. You can change the perspective by going to the menu item Windows + Perspective > Open Perspective > More… Use Window > Show View > Other to open a new part in your current perspective.

Java Eclipse perspective

The Package Explorer contains the current project you’re working on. The View menu on the toolbar lets you view the components of a package. You can double-click on a class to open it in the editor. In the structure view, you can see the source file currently selected. The issue view works like a database that lists all the compile-time errors in your code. To open it, go to Window > Show View > Issues.

Advantages:

• free support environment;
• multilingualism;
• extensibility and fine-tuning through additional plug-ins are available;
• a large community has been formed around the IDE to help solve problems;
• customizable interface;
• the ability to integrate JUnit and perform test optimization.

IntelliJ Features

IntelliJ IDEA has some of the most effective Java code completion features. Its prediction algorithm can accurately guess what the coder is trying to type and completes it for him even if he does not know the exact name of a particular class, member or any other resource.

Deep Understanding

IntelliJ IDEA really understands and deeply comprehends your code as well as the coder context, which is what makes it so unique among other Java IDEs.

Intelligent Code Completion – It supports contextual code completion. It gives a list of the most significant characters applicable in the current context.

Chained Code Completion – This is an advanced code completion feature that lists the relevant symbols available via get methods or methods in the current context.

Static member completion – It allows you to use static methods or constants and automatically adds necessary import statements to avoid compilation error.

Duplicate Detection – It detects duplicate code fragments on the fly and gives a notification / suggestion about it to the user.

Inspections and quick fixes. Whenever IntelliJ detects that you are about to make a mistake, a little lightbulb notification appears on one line. Clicking on it will give you a list of suggestions.

The main feature I liked is remote code editing, similar to Sublime, if you add SFTP plugins to it. Version 8 also includes visual scrolling, similar to Sublime.

Komodo IDE is a commercial development environment, which is based on Komodo Edit and has a number of additional features, such as code debugging (including remote debugging), refactoring, working with VCS, HTTP Inspector, Rx Toolkit, integrative shell, unit tests, integration with other products of the company (Stackato, Perl Dev Kit and TCL Dev Kit) and other small things.

The text editor supports a large number of languages for syntax highlighting, autocomplete, Intellisense.

Advantages:

• Code autocompletion and Intellisense syntax highlighting;
• visual debugger;
• multi-language;
• integration with version control systems;
• free version for individuals ;
• allows you to customize your workspace;
• has a visual debugger and testing tools.

Disadvantages:

• for team or enterprise level work, there is a paid version.

Just like a lot of well-made Python development environments, Spyder IDE has a simple and useful code editor, debugger, log history, and built-in console. In addition it has a few features aimed specifically at a scientific audience, like multiple IPython consoles, static code analysis, and a unique variable browser panel. As for the graphical user interface (GUI), Spyder utilizes the Qt framework written in C++.

A variety of scientific packages like NumPy or SciPy, which are immediately integrated into Spyder. If that’s not enough, you can choose from a wide variety of addons and get even more functionality – like integration of a unit testing framework or improved memory management. Note, however, that even the best IDEs for Python will have degraded performance if you overload them with too many plugins.

Advantages

• free integrated development environment;
• ability to view variable values;
• available error analysis function with hints in case of finding errors;
• code autocompletion;
• cross-platform, makes it possible to work on Windows, macOS, Linux.

Disadvantages

• The tool is largely intended for working with data. For other tasks it is not as good as other IDEs.
