java - Timeout for function -

-

How can I do this in Java? To be more preses I would like to end the time for my function.

Pseudo-code: 

  public string aLotOfWork () {hardwork (return)); If (hardwalk (still being executed after 30 seconds) return "timeout"; }   
 I can use timer for this, but I can not return any value to the timer function run () from my upper function  
  Timer task = new timer tasks () {public zero run () {return ""; // timer task run should be zero }}; Timer timer = new timer (); Timer Scheduler (work, 50000, 1);   
  
 
 
 Check the class This is a code called "timecode" (timeout, time unit). Provides . Public string aLotOfWork () {Future Task Function = New Future Tasks & lt; String & gt; (New callable & lt) Load  hardwork  task to  futuresksk  class load  
  ; String & gt; () {Public string call () {return hard ();}}); Try {Return task.get (30, time unit SECONDS); } Hold (timeout Exception e) {return "timeout"; } Hold (exception e) {return "timeout"; // or whatever you like}}

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
