Use the -cp parameter to add the JAR to the classpath, so that the JVM can load its internal classes and resources, such as java-cplibrary.jarcom.example.Main, which supports multiple JARs separated by semicolons or colons, and can also be configured through CLASSPATH environment variables or MANIFEST.MF.

The most direct way is to recall the storage location, usually in folders such as desktop, documents, downloads, etc.; if it cannot be found, you can use the system search function. File "missing" is mostly due to problems such as unattention of the saving path, name memory deviation, file hiding or cloud synchronization. Efficient management suggestions: Classify by project, time, and type, make good use of quick access, clean and archive regularly, and standardize naming. Windows search and search through File Explorer and taskbar, while macOS relies on finder and Spotlight, which is smarter and more efficient. Mastering tools and developing good habits is the key.

First check whether the network connection is normal. If other websites cannot be opened, the problem is on the network; 1. Clear the browser cache and cookies, enter Chrome settings and select clear browsing data; 2. Close the extension, and you can use the scarless mode to test whether it is caused by plug-in conflicts; 3. Check and close the proxy or VPN settings to avoid network connection being intercepted; 4. Reset Chrome network settings and restore the default configuration; 5. Update or reinstall Chrome to the latest version to solve compatibility problems; 6. Use other browsers to compare and test to confirm whether the problem is only Chrome; according to error prompts such as ERR_CONNECTION_TIMED_OUT or ERR_SSL_PROTOCOL_ER

Use the implements keyword to implement the interface. The class needs to provide specific implementations of all methods in the interface. It supports multiple interfaces and is separated by commas to ensure that the methods are public. The default and static methods after Java 8 do not need to be rewrite.

Real-time systems require deterministic responses, because correctness depends on the result delivery time; hard real-time systems require strict deadlines, missed will lead to disasters, while soft real-time allows occasional delays; non-deterministic factors such as scheduling, interrupts, caches, memory management, etc. affect timing; the construction plan includes the selection of RTOS, WCET analysis, resource management, hardware optimization and rigorous testing.

First, enable the built-in scaling function of UC browser, go to Settings → Browse Settings → Font and Typesetting or Page Scaling, and select a preset ratio or custom percentage; second, you can force the page display size by opening or pinching gestures with two fingers; for web pages that restrict scaling, you can request the desktop version of the website to unlock the restrictions; advanced users can also modify the viewport attributes by executing JavaScript code in the address bar to achieve a more flexible forced scaling effect.
