How to search for a string in Java source code and identify in which method it is in -


what need map classes , methods of java source code have inside implementations specific string. translating in real example: need build java application scans java source file searching specific string (a database field example). after finding string need have output in class/method find. so, if have following code:

public class exampleclass{    public static void main(string args[]) {     string url = "hello1";   }    public void function1(){     string hello2 = "aaaaaa";   } }

in case, if search "hello1" should return like: exampleclass.main. , if search hello2 should return me: exampleclass.function1

thanks lot in advance!

from description first sounds use tool grep scan files. solution, scan files looking occurrence of "hello1" if sufficient needs. output quite customizable. using grep command line:

$ grep -r "hello1" /home/user/workspace/project/src

given /home/user/workspace/project/src project source code root. there implementations of grep windows, make sure version using supporting recursion via r switch, not implementations do. can call grep java application using system.exec. read resulting process's output stream results.

however, if need parse source code in order make sure expression looking proper string literal @ right place may want use eclipse jdt. reckon might overkill trying achieve since need parse entire project rather complex job.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
