Clojureis a general-purpose functional programming language.The language runs on JVM as well as Microsoft’sCommon Language Runtime. Clojure is a compiled language still, it remains dynamic, as its features are supported at runtime. The Clojure designers wanted to design modernLispwhich can run o...
6- Compilation and Execution on Virtual Machines 虚拟机; 虚拟机执行指令流是在软件上而非硬件上; 已经被很多种语言所采纳; java编译器生成的bytecode是被 JVM解释了,JVM通过 JIT compilation将 bytecode转换成machine code; 在本地平台上编译好的Program; 可以在不同的平台上运行,只要大家都装了虚拟机;发布...

Programming languages built for the JVM can be used to write programs that can run on a wide range of platforms without modification and can even leverage all the libraries and frameworks that exist for the JVM. In this article, Toptal engineer Federico Tomassetti presents an overview of the st...
Code written in the Java programming language might also call directly into native-compiled code, either C, C++, or Fortran; the targets of such calls are referred to as native methods. Applications written in the Java programming language are inherently multithreaded, and have one JVM software ...

It was not possible in case of a jar file. Using modules we can specify what all are required right before the application runs so that the JVM will check if everything and then only it starts the app. So, using modules we can get rid of “noClassDefFoundError”. With modules, we can...
Spark SQL caches DataFrames (when you call dataFrame.cache) using an in-memory columnar format which is optimized to: scan only required columns, automatically tune compression, minimize memory usage and minimize JVM Garbage Collection. Spark SQL Vectorized Parquet and ORC readers decompress and decod...
bytecode is the machine language for JVM Java程序分为applications和applets Algorithm: A step-by-step problem-solving process in which a solution is arrived at in a finite amount of time. 两种编程方式: structured programming/top-down design/bottom-up design/stepwise refinement/modular programming:把...
Remote Method Invocation (RMI) enables the development of distributed applications by providing for remote communication between programs written in the Java programming language. RMI enables an object running in one Java Virtual Machine to invoke methods on an object running in another Java VM, which...
