Creating a language that compiles to Java bytecode requires a deep understanding of the inner workings of the Java Virtual Machine. To appreciate what Scala’s developers have accomplished, it is necessary to go under the hood, and explore how Scala’s source code is interpreted by the compile...
Scala is a Java-like programming language that can call Java methods, inherit from Java classes, implement Java interfaces, and create Java objects. The source code can be compiled to Java byte code that can run on a Java virtual machine. The language also supports optional parameters, raw st...
Bytecode is computer object code that an interpreter converts into binarymachine codeso it can be read by a computer's hardware processor. The interpreter is typically implemented as a virtual machine (VM) that translates the bytecode for the target platform. The machine code consists of a set...
Scala code style: in this blog we discuss all types of code styles available for the Scala programming language today (adopted from ScalaBay)
what is conversion exit defined in ABAP domain 我们之前用了这个data element。 UI framework的getter 会自动检测data type的domain上是否维护conversion exit,如果有,就自动调用,我们没有写任何代码。 还是这个routine只控制ui field? Conversion exit 有 in 和 out 这一对,out 负责data 输出的时候,自动被gui ...

Apache Sparkis a free and open-source cluster-computing system created to process and analyze big data on a distributed computing system (a cluster). Along with the Python, Scala, and Java APIs, which expose principles of distributed computing, they are useful for developers who work on larger...
Spark and Hadoop have a few similarities. Both are open-source frameworks for analytic data processing; both live in the Apache Software Foundation; both contain machine learning libraries; and both can be programmed in several different languages, such as Java, Python, R or Scala. ...
