AOT(Ahead of Time Compilation) 在程序被执行前就将其编译成机器码,属于静态编译(C、 C++,Rust,Go 等语言就是静态编译)。 AOT 避免了 JIT 预热等各方面的开销,可以提高 Java 程序的启动速度,避免预热时间长。 AOT 还能减少内存占用和增强 Java 程序的安全性(AOT 编译后的代码不容易被反编译和修改),特别...
Checked Exceptionis a checked exception. During the compilation process of Java code, if the checked exception is not processed by thecatchorthrowskeyword, it cannot pass the compilation. For example, the following code for IO operation: Except forRuntimeExceptionand its subclasses, the otherExcepti...

Embedded Java compilation and linking diagram. Java byte code is target code intended to be platform independent. In order for the Java byte code to run on an embedded system, a Java Virtual Machine (JVM) must exist on that system. Real-world JVMs are currently implemented in an embedded ...
Sometimes the compilation process is a long chain involving many tools. Programming in machine code is an art of the past. The advantages of using a high-level language fairly compensate for the extra effort using the compiler chain. In technical documentation, the advantages, at least in the ...

Note that Java involves the just-in-time (JIT) compilation process, and therefore warm-up may be required during stress testing. If the stress test results meet the expected optimization goals or represent a significant improvement compared with the benchmark data, we can continue to use tools ...
. Compilation, unit tests and code quality gate(s) is the bare minimum. If you have integration and chain tests, wonderful. But make sure the build does not take long. Immediate feedback is important. If needed, create a separate build scheduled less frequently for slower tests (integration...
