Abstraction means ignoring irrelevant features, properties, or functions and emphasizing the relevant ones...relevant to the given project (with an eye to future reuse in similar projects).
The case is used to label each branch in a switch statement. Examples int arg = <some value>; switch (arg) { case 1: <statements> break; case 2: <statements> break; default: <statements> break; }
The catch keyword is used to define exception handling blocks in try−catch or try−catch−finally statements. Examples try { <block that may throw exceptions> } catch (<java.lang.Exception or subclass> e) { <code to handle exception e> } try { <block that may throw different exceptions> } catch (FooException e) { <code to handle FooException e> } catch (BarException e) { <code to handle BarException e> } try { <block that may throw exceptions> } catch (<java.lang.Exception or subclass> e) { <code to handle exception e> } finally { <statements that execute with or without exception> }
Here is a list of keywords in the Java programming language. You cannot use any of the following as identifiers in your programs. The keywords const and goto are reserved, even though they are not currently used. true, false, and null might seem like keywords, but they are actually literals; you cannot use them as identifiers in your programs. The abstract Keyword The boolean Keyword The break Keyword The byte Keyword The case Keyword The catch Keyword The char Keyword The class Keyword The continue Keyword The default Keyword The do Keyword The double Keyword The else Keyword The extends Keyword The false Keyword The final Keyword The finally Keyword The float Keyword The for Keyword The if Keyword The implements Keyword The import Keyword The instanceof Keyword The int Keyword The interface Keywo...
I liked the explanation, especially because of the code sample. Good job.
