How does the JVM manage garbage collection across different platforms?Apr 28, 2025 am 12:23 AMJVMmanagesgarbagecollectionacrossplatformseffectivelybyusingagenerationalapproachandadaptingtoOSandhardwaredifferences.ItemploysvariouscollectorslikeSerial,Parallel,CMS,andG1,eachsuitedfordifferentscenarios.Performancecanbetunedwithflagslike-XX:NewRa
Why can Java code run on different operating systems without modification?Apr 28, 2025 am 12:14 AMJava code can run on different operating systems without modification, because Java's "write once, run everywhere" philosophy is implemented by Java virtual machine (JVM). As the intermediary between the compiled Java bytecode and the operating system, the JVM translates the bytecode into specific machine instructions to ensure that the program can run independently on any platform with JVM installed.
Describe the process of compiling and executing a Java program, highlighting platform independence.Apr 28, 2025 am 12:08 AMThe compilation and execution of Java programs achieve platform independence through bytecode and JVM. 1) Write Java source code and compile it into bytecode. 2) Use JVM to execute bytecode on any platform to ensure the code runs across platforms.
How does the underlying hardware architecture affect Java's performance?Apr 28, 2025 am 12:05 AMJava performance is closely related to hardware architecture, and understanding this relationship can significantly improve programming capabilities. 1) The JVM converts Java bytecode into machine instructions through JIT compilation, which is affected by the CPU architecture. 2) Memory management and garbage collection are affected by RAM and memory bus speed. 3) Cache and branch prediction optimize Java code execution. 4) Multi-threading and parallel processing improve performance on multi-core systems.
Explain why native libraries can break Java's platform independence.Apr 28, 2025 am 12:02 AMUsing native libraries will destroy Java's platform independence, because these libraries need to be compiled separately for each operating system. 1) The native library interacts with Java through JNI, providing functions that cannot be directly implemented by Java. 2) Using native libraries increases project complexity and requires managing library files for different platforms. 3) Although native libraries can improve performance, they should be used with caution and conducted cross-platform testing.
How does the JVM handle differences in operating system APIs?Apr 27, 2025 am 12:18 AMJVM handles operating system API differences through JavaNativeInterface (JNI) and Java standard library: 1. JNI allows Java code to call local code and directly interact with the operating system API. 2. The Java standard library provides a unified API, which is internally mapped to different operating system APIs to ensure that the code runs across platforms.

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),
