![]() ![]() These features work together to help you optimize speed and memory usage and reduce overhead.Īs NetBeans was acquired by the Apache Software Foundation in early 2018, you can expect more integrations and extended features in the future - especially as Apache already hosts many of Java projects from the Maven build tool to the Tomcat server. With the profiler, you can check memory usage, CPU performance, thread states, and other characteristics of your Java application. If you use NetBeans, you also get access to the built-in NetBeans Profiler tool. With the Visual Debugger, you can add listeners to GUI actions, view component properties and the hierarchy of components, and locate the source code. NetBeans also provides you with the handy Visual Debugger feature so you can debug the visual elements of your Java and JavaFX GUI applications. NetBeans allows you to set up breakpoints and conditional breakpoints, step through the code, switch threads, and monitor execution in real-time. In fact, both are excellent debugging tools to inspect the source code and identify issues such as memory leaks and concurrency problems. The NetBeans Debugger has many similar features to Eclipse. The latter also has support for HTML5, JavaScript, and the GlassFish and Tomcat servers, so it’s a better choice for more serious development work. NetBeans comes in different download bundles for Java, you will need either the Java SE or the Java EE edition. Like Eclipse, the debugging functionalities are built into the platform, so you only need to download the IDE to get the debugging tool. NetBeans is another free and open-source IDE. With Eclipse, you can also suspend and resume threads, step through the execution of the program, inspect values, and evaluate expressions. One of the best features of Eclipse is the Debug Perspective, which shows relevant debugging information side-by-side, such as variables, breakpoints, threads, and call stacks. A big advantage is that the Eclipse workflow is convenient because you can use the same platform for both development and debugging. The Eclipse platform comes with advanced debugging features that help you inspect your code during execution, making it a well-rounded tool. EclipseĮclipse is a popular open-source IDE that’s used for Java development, but it also has plugins for other languages like PHP, Python, Ruby, and C#. Advanced features like Breadcrumbs, Filters, and Custom Tags make the debugging process easier, too. ![]() Raygun can process any object that inherits from the Throwable class. The installation and configuration doesn’t take more than a few minutes. You can send all your exceptions to your Raygun dashboard so that you can see a detailed diagnosis for each error, including full stack traces, data related to method, function and class names, and more. Raygun4Java allows you to send exceptions from desktop and console Java and Scala apps by default. Raygun Error Monitoring has everything you need to discover bugs, errors, and crashes that happen in production and beyond. One of the hardest things about debugging is that you don’t always know which errors your users are experiencing. This list of Java debugging tools will help you evaluate your options quickly so you can find the best for the job. ![]() Java debugging tools exist to help us resolve errors faster, so we can get on with doing what we do best. But, software errors are an inevitable part of a developer’s life. ![]() In an ideal world, bugs would never reach production. This article was last updated January 2020 The most basic example of using the library would look like this: BufferedImage thumbnail = Scalr.resize(image, 150) Īnd a more typical usage to generate image thumbnails using a few quality tweaks and the like might look like this: import static .6 Java debugging tools you should know By Anna Monus | Posted | 7 min. Imgscalr is pure-Java image resizing (and simple ops like padding, cropping, rotating, brighten/dimming, etc.) library that is painfully simple to use - a single class consists of a set of simple graphics operations all defined as static methods that you pass an image and get back a result. I know this question is quite old, but as new software comes out it does help to get some new links to projects that might be interesting for folks. ![]()
