CSS stands for Cascading Style Sheets and is a styling language used to define the look and feel of web documents. JavaFX, on the other hand, is an application platform that is used to create rich internet applications. JavaFX stylesheets are used to define the look and feel of JavaFX based applications. CSS is more commonly used with web documents, while JavaFX is used strictly with desktop applications.

There are several ways to shuffle an array in JavaScript. One of the more popular ways is as follows: // Create a copy of the original array. We will use this copy to perform our shuffle. let arrayCopy = [...array]; // Loop over the arrayCopy and for each element randomly pick another element from the arrayCopy // and swap the two elements. for (let i = 0; i < arrayCopy.length; i++) { let randomIndex = Math.floor(Math.random() * arrayCopy.length); let temp = arrayCopy[i]; arrayCopy[i] = arrayCopy[randomIndex]; arrayCopy[randomIndex] = temp; } // Return the now-shuffled arrayCopy return arrayCopy;

1. Java Flight Recorder (JFR): This monitoring tool helps uncover the root cause of problems and performance issues. It provides developers with insight into Java application performance and assists with tuning applications and optimizing for performance. 2. Java Mission Control (JMC): This is an advanced profiling and diagnostics tool for Java applications. It is a powerful tool for troubleshooting Java performance and isolating application problems. 3. Java Virtual Machine Tools (JVMTI): This is a set of tools that provide the ability to instrument and monitor Java Applications by observing and manipulating the state of a running JVM. JVMTI can be used to detect memory leaks, potential threading issues and more. 4. VisualVM: This is a visual overview of the running applications and the active JVM processes. With VisualVM you can view memory utilization, network traffic and various other metrics. 5. JMX (Java Management Extensions): This provides the ability to connect to a running application and monitor it from an external application. JMX can be used to detect memory leaks, monitor the JVM, and view application performance metrics such as memory usage, CPU usage and thread counts.

Lazy loading Javascript in blogger is a tool that allows you to optimize your blog by loading JavaScript snippets only when they are needed. This can increase the speed of your blog by allowing it to only pull the code when it is needed. It can be especially beneficial if you are using a lot of code on a page, as it will help reduce page loading times.

Void 0 is a statement used in JavaScript to evaluate an expression and then immediately discard the return value, usually to avoid a JavaScript warning. It is often used in place of undefined to mean the same thing.

1. To get a Javacore dump: - On Windows: you can use the jcmd command with the help of Java Virtual Machine (JVM) Process Identifier (PID). - On Linux/UNIX: use the kill –3 PID command, where PID is the process identifier of the JVM. If a system core dump is enabled, the javacore and a system core dump will appear in the directory. 2. To get a system core dump: - On Windows: open the command prompt and type “Ctrl+Break” to generate a system core dump. - On Linux/UNIX: use the “kill –6 PID” command, where PID is the process identifier of the running Java application. The system core dump will be generated in the same directory.

To enable JavaScript, you will need to access the “Settings” or “Preferences” menu in your web browser and locate the section for JavaScript. Once you find the JavaScript section, select the option to “Enable” JavaScript and close the Settings or Preferences tab.

A default button in JavaFX is a button that will automatically be activated when a user presses the Enter or Return key. It is usually used to trigger the most important action of a given dialog.

The Java virtual machine (JVM) can go out of memory for a number of reasons. Common causes include: inadequate heap size, excessive garbage collection, memory leaks, poorly written/optimized code, and application or system bugs.

1. Download and install Java Development Kit (JDK) and Gradle. 2. Create a project directory and setup the build.gradle file. 3. Add the necessary plugins and dependencies to the build.gradle file for Cucumber to run. 4. Create a features directory and add the cucumber feature files. 5. Create a TestRunner class with the necessary annotations and configurations. 6. Create StepDefinition classes with methods corresponding to the steps of the feature files. 7. Run the TestRunner class. 8. Cucumber will compile the feature files, compile the step definitions and execute the test cases.
