Is there a way to view the C code underlying Java? -

-

i know can view "source code" java on places grepcode, i'm looking way view c code java built on top of. feel question must have been asked many times, haven't been able find satisfactory answer.

this not explicit purpose - want understand how programming language "built" little bit better.

also, if show how view bytecode generated, too.

oracle's official jdk 7 based on code the openjdk project, can download link. there's jdk 8 branch available same site.

the java virtual machine (jvm) sort of imaginary computer executes *.class files. of time, jvm emulated program written in other language (like c++) runs on real computer. when run java program on windows machine, example, program java.exe written largely in c++, pretends jvm, , executes *.class files. java code like

++i;

gets translated java compiler (which written in java!) jvm opcode like

iinc 0 1

the jvm contains code (written in c++, or assembly) handle instruction -- , hundreds of additional instructions -- if opcode in real machine language. in truth, it's more complicated: modern jvms translate jvm opcodes platform-specific machine code while they're running, code translation of course written in native (non-java) language c++ or assembly.

there lots of articles on interwebs explain stuff well: here's nice one.

What design pattern is this code in Javascript? -

-
this question has answer here: why write “.call(this)” @ end of javascript anonymous function? [duplicate] 4 answers what kind of design pattern , significance of using closure? (function(){ // code here }).call(this); edit then difference between above code , following this keyword still refer same object in both ways. (function(){ // code here })(); thats invoked function expression. more info here: http://benalman.com/news/2010/11/immediately-invoked-function-expression/ the purpose run code while protecting scope (so variables declared within don't leak out global scope. update call sets value of this function being applied on. without it, value set window object, there set outer scope.
