A Java Visualizer or java explainer is a tool that is basically used to observe memory and output that the program executes or carries out.
It is vital for aspiring computer scientists to understand the ways in which individual Java statements are carried out.
This also includes the output assembled and how the statements alter the elements of memory during the same time when the program is functioning. Experts have developed and created tools that do this.
Students studying CS have the ability to attach excerpts to the framework and subsequently launch the program. This is done in steps using the statements and they observe an uncomplicated representation of memory.
By using this procedure, people will see how the memory alters and they will realize why the code puts together a particular result.
This also assists people in properly copying their code and learning how to do this precisely is a crucial skill that all programmers should have.
So here are the top 10 best java code visualizers you can use online.
Top Online Java visualizer tools
1. Java Visualizer (Online Application Tool)
Java Visualizers are easily accessible on the web. People are not required to register; however, they can follow up on the improvement and progress while operating on programming languages using different sources and websites that give brief instructions and tutorials.
After visiting the website that provides the visualizer, people must type in a code using principal methods. After doing this, they should press the visual implementation or execution icon.
They will observe what is arranged in memory or the output. The users should then repeat the process till all the statements are carried out and the program is concluded.
Lastly, people can then modify the code with individual statements that they would like to analyze and repeat the steps mentioned.

2. Java Code Visualizer (Plugin for Eclipse)
The bytecode visualizer is an implement that can be utilized to visualize and diagnose the Java Byte code. There are many features included such as the endorsement of classes, areas, and procedures followed involving the Java provider.
Moreover, there are comments that make it uncomplicated to be familiar with the instructions and their framework. People are brought with self-explanatory scopes of deviation handlers.
Lastly, the users are provided with easy accessibility when to comes to shifting between bytecode and source code.
The flow diagram is drawn out right next to the bytecode, this enables users to understand the execution tracks of the provided method. The class file summary is adjusted or integrated into both ways with the viewer.
Next comes the source code visualizer, which is also used for visualizing but it works differently.
The flow diagram is drawn out next to the source code instead and it involves three fundamental elements that include the source code modifier, the control flow graph console, and the adjustment of the control flow graph with the source code modifier.
5. Java Visualizer for intelliJ IDEA (plugin)
This plugin is easy to install, and created for IntelliJ IDEA. It helps in visualizing call stacks and objects in heap. The latest version 2.2.0 is compatible with the current version of IntelliJ IDEA.
Programmer can debug their code line by line and easily go through the code and understand it better. More help on how to use this Plugin can be found here.
There are different types of visualization operating systems and methods, and graphical visualization comes under them. This method allows users to represent constructional information or content as diagrams of non-pictorial graphs or networks.
The method plays an essential role in the field of networking, web programming, database, and a lot more.
Many sources provide graphical visualization to users, and the arrangement programs use a representation of graphs in an uncomplicated text language for reference.
The programs also create diagrams in practical formats such as images for different websites. People are brought it multiple features for solid diagrams such as the choice of colors, layouts, design, shapes, and more.
Users will come across overlaid diagrams of directed graphs, this is a basic implementation to utilize if the vertices impose direct meaning.
Next comes the spring model arrangements, this is used if the graph has a moderate size with about a hundred nodes and if people are not that familiar with it.
Code can be created and interacted with using the zooming user interface. This method also follows a visualization process that involves software projects such as graphs and modeling structures, this allows users to visualize their project in its entire form.
This method views each reliance as a node inside graphs at great levels. In reality, the code base is usually based on multiple open and closed source libraries.
In most cases, fractals are self-alike designs or patterns, this suggests that they do not change if looked at from near or far.
Considering this, a software project is generally a fractal by design, sources categorize files in directories, and individual code files are a group of methods.
This process’s objective is to visualize individual code bases entirely and comprehensively, this makes them visually engaging and satisfying. It will implant maximum information that will save a lot of time for users since it can be a long and complicated procedure.
After the first glimpse, users observe that there are multiple methods in a single class, they look over the sections of their projects that are not properly tested, the sections that are used a lot or less, and more. The area that individual nodes occupy correlates with the size of the file or the directory it depicts.
The shape or form of the node indicates what type it is, the types include file, method, etc. The color represents the status, whether the node is failing or passing, the percentage tested, and how much it is used. Lastly, people can zoom and navigate effortlessly.
8. Jeliot 3 (Code Visualization application)
It’s a desktop application that works with one Java Code. The application is available for download under General Public License.
It shows a full interpretation of the Java program line by line using animation. It displays variable initialization, method calls, etc on screen.
Application is excellent for students who are learning Java and want to understand the Java code inside out. The working of this application can be seen on YouTube.
9. Source Code Visualization (Desktop Application)
Code bases can now be learned swiftly by users and they can start working on newer projects after referring to visualization sources. Users can determine the costs of possible changes by looking at the areas where functions and items are utilized.
The source insight resolves and analyzes entire projects and enables users to navigate and modify code effortlessly. Information appears instinctively and quickly.
A crucial benefit of using visualization is that users can now view the places where the functions and variables are used. The source insight also gives references to different classes and variables rapidly.
Users can easily go through their projects using developed search features. There are effective analyzing features for different programming languages such as C/C++, C#, Java, Objective-C, etc.
Other features include editing and formatting features. Good and strong editing features prove to helpful that enable users to work with code excerpts, automatic completion, and renaming.
People can view important references involving variables and other statements using formatting. The identifiers are formatted depending on the statement, the utilization, and the scope.
- It assists users to understand complicated code-bases
- Users can navigate function calls rapidly
- It becomes easy to discover references to functions and variables
- Class graphs and diagrams can be viewed
- Users can review functions and class definitions without opening and viewing different files
- There are useful features for editing that include code excerpts, automatic completion, and renaming.
- Effective information panels can be utilized to produce a high-yielding workflow.
