This article mainly introduces the detailed explanation and examples of Java exception handling runtime exceptions (RuntimeException). Friends in need can refer to http://time.qq.com/?pgv_ref=aiotime Java exception handling runtime Detailed explanation of exception (RuntimeException) and examples RuntimeException RunntimeException subclass: ClassCastException In polymorphism, you can use Instanceof judgment to avoid ArithmeticException for if judgment. If the divisor is 0, returnNullPointerException for if judgment. If it is nullArrayIndexOutOfBoundsException, use the array length attribute to avoid These exceptions that cross the boundary can be avoided through good programming habits of programmers 1: There is no need to handle runtime exceptions, directly find the code in question and avoid them

##2.Multi-threaded code example for catching and processing RuntimeException
##Introduction: Under the multi-threading mechanism, We cannot cross threads and catch exceptions from other threads in the main thread. For non-runtime exceptions, when there are many and complex threads, it is difficult to write an exception handler for each thread. For runtime exceptions, if we cannot take some useful action, the exception will be thrown to the console. For example, the following example: package AllThread;/*** * @author QuinnNorris * * Catch exceptions*/public cl

Java multi-thread programming example of catching sub-thread exceptionsIntroduction: All threads in a java multi-threaded program are not allowed to throw uncaught checked exceptions, that is to say, each thread You need to handle your own checked exception yourself. But what is unavoidable is the unchecked exception, which is RuntimeException. When an exception is thrown, the sub-thread will end, but it will not affect the main thread

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

Reasons for writing platform-specific code in Java include access to specific operating system features, interacting with specific hardware, and optimizing performance. 1) Use JNA or JNI to access the Windows registry; 2) Interact with Linux-specific hardware drivers through JNI; 3) Use Metal to optimize gaming performance on macOS through JNI. Nevertheless, writing platform-specific code can affect the portability of the code, increase complexity, and potentially pose performance overhead and security risks.

Java will further enhance platform independence through cloud-native applications, multi-platform deployment and cross-language interoperability. 1) Cloud native applications will use GraalVM and Quarkus to increase startup speed. 2) Java will be extended to embedded devices, mobile devices and quantum computers. 3) Through GraalVM, Java will seamlessly integrate with languages such as Python and JavaScript to enhance cross-language interoperability.

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),
