Code lens is a simple way to know what happens with the code. Here you could find an image with the number of references of a method or class. If you can't see the code lens please see this question: Missing CodeLens references count in VS 2015 Community edition

Sometimes you may want to have a lambda expression implementing more than one interface. This is mostly useful with marker interfaces (such as java.io.Serializable) since they don't add abstract methods. For example, you want to create a TreeSet with a custom Comparator and then serialize it and se...

To obtain a reference to a KClass object representing some class use double colons: val c1 = String::class val c2 = MyClass::class

To obtain a Java's Class object from Kotlin's KClass use the .java extension property: val stringKClass: KClass<String> = String::class val c1: Class<String> = stringKClass.java val c2: Class<MyClass> = MyClass::class.java The latter example will be optimized by the compile...

Given that the 8086/8088 was used in the IBM PC, and the Operating System on that was most often from Microsoft, Microsoft's assembler MASM was the de facto standard for many years. It followed Intel's syntax closely, but permitted some convenient but "loose" syntax that (in hindsight) onl...

Intel wrote the specification of the 8086 assembly language, a derivative of the earlier 8080, 8008 and 4004 processors. As such, the assembler they wrote followed their own syntax precisely. However, this assembler wasn't used very widely. Intel defined their opcodes to have either zero, one or tw...
