#java What should I do if I can’t find the jar? The solution to the jar package cannot be found
1. Right-click the project-"Properties-"Java bulk path-"jre System Library-"access rules-"resolution select accessible, fill in ** below and click OK! ! !
Recommended tutorial: "java learning"
2. When writing Java code in MyEclipse, a certain jar is used, import sun.misc.BASE64Decoder.*; But MyEclipse prompts:
Access restriction: The type *Decoder is not accessible due to restriction on required library C:\Program files\java\jre7\lib\rt.jar Access restriction : The constructor *BASE64Decoder() is not accessible due to restriction on required library C:\Program files\java\jre7\lib\rt.jar
Solution 1:
Just remove the JRE System Library in the project build path, then add the library JRE System Library, and everything will be normal after recompiling.
Solution 2:
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning

Emerging technologies pose both threats and enhancements to Java's platform independence. 1) Cloud computing and containerization technologies such as Docker enhance Java's platform independence, but need to be optimized to adapt to different cloud environments. 2) WebAssembly compiles Java code through GraalVM, extending its platform independence, but it needs to compete with other languages for performance.

Different JVM implementations can provide platform independence, but their performance is slightly different. 1. OracleHotSpot and OpenJDKJVM perform similarly in platform independence, but OpenJDK may require additional configuration. 2. IBMJ9JVM performs optimization on specific operating systems. 3. GraalVM supports multiple languages and requires additional configuration. 4. AzulZingJVM requires specific platform adjustments.

Platform independence reduces development costs and shortens development time by running the same set of code on multiple operating systems. Specifically, it is manifested as: 1. Reduce development time, only one set of code is required; 2. Reduce maintenance costs and unify the testing process; 3. Quick iteration and team collaboration to simplify the deployment process.

To solve platform-specific problems in Java applications, you can take the following steps: 1. Use Java's System class to view system properties to understand the running environment. 2. Use the File class or java.nio.file package to process file paths. 3. Load the local library according to operating system conditions. 4. Use VisualVM or JProfiler to optimize cross-platform performance. 5. Ensure that the test environment is consistent with the production environment through Docker containerization. 6. Use GitHubActions to perform automated testing on multiple platforms. These methods help to effectively solve platform-specific problems in Java applications.

The class loader ensures the consistency and compatibility of Java programs on different platforms through unified class file format, dynamic loading, parent delegation model and platform-independent bytecode, and achieves platform independence.

The code generated by the Java compiler is platform-independent, but the code that is ultimately executed is platform-specific. 1. Java source code is compiled into platform-independent bytecode. 2. The JVM converts bytecode into machine code for a specific platform, ensuring cross-platform operation but performance may be different.

Multithreading is important in modern programming because it can improve program responsiveness and resource utilization and handle complex concurrent tasks. JVM ensures the consistency and efficiency of multithreads on different operating systems through thread mapping, scheduling mechanism and synchronization lock mechanism.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
