The speed of a computer processor, or CPU, is determined by the Clock Cycle, which is the amount of time between two pulses of an oscillator. Generally speaking, the higher number of pulses per second, the faster the computer processor will be able to process information. The clock speed is measured in Hz, typically either … Read more
class A class is the blueprint for creating objects in class-based object-oriented programming; you should learn the basics of OOP and understand what an object is, what a class is, what is inheritance, polymorphism, encapsulation before learning anything else about Java. package A package is a namespace; it let’s you handle naming conflicts. It basically … Read more
I disagree. If you pass a parameter by reference to a function, you would be able to modify that value outside the scope of the function. Furthermore, functions do not have to return a value. Consider void some_func() in C. So the premises in the OP are invalid. In my mind, the difference between function … Read more
The pattern is called self-invocation, a self-invoking function. It can create a closure, but that is an effect of the pattern (perhaps the intended effect), not the pattern itself.
Abstraction is a core concept in all of computer science. Without abstraction, we would still be programming in machine code or worse not have computers in the first place. So IMHO that’s a really good question. What is abstraction Abstracting something means to give names to things, so that the name captures the core of … Read more
Hard tabs use the tab character, http://en.wikipedia.org/wiki/Tab_key#Tab_characters Soft tabs are just spaces. Soft tabs are usually either 2 or 4 spaces, depending on convention. If you set your editor to use “soft tabs,” when you press the Tab key on your keyboard your editor will insert spaces instead of the tab character.
A finite state transducer (FST) is a finite state automaton (FSA, FA) which produces output as well as reading input, which means it is useful for parsing (while a “bare” FSA can only be used for recognizing, i.e. pattern matching). An FST consists of a finite number of states which are linked by transitions labeled … Read more
This is based on the Expression Evaluator grammar by Terrence Parr. The grammar for this example: grammar Expr002; options { output=AST; ASTLabelType=CommonTree; // type of $stat.tree ref etc… } prog : ( stat )+ ; stat : expr NEWLINE -> expr | ID ‘=’ expr NEWLINE -> ^(‘=’ ID expr) | NEWLINE -> ; expr … Read more
This is not Java EE related. This is IDE related. The term is at its own not programming related. From http://www.thefreedictionary.com/facet fac·et (fst) n. One of the flat polished surfaces cut on a gemstone or occurring naturally on a crystal. Anatomy A small, smooth, flat surface, as on a bone or tooth. Biology One of … Read more
The domain is what you are modelling. If you are modelling a business problem, they are the same thing. If you are modelling something else, physics for instance, there is probably no business logic in your system, but the physics parts are still domain logic.
