java - Error: insert enum identifier and enum body -

-

This is my code, both syntax errors are more specifically on line 16 "private getTotalGrains (k, grains);" By reading other similar questions, can there be something to write the method inside any other method? If I do not think there is enough experience to see it, then it will be amazing. Import java.util.Scanner; Public square grains {public static zero main (string [] args) {{grain = new grain (); Grain.getTotalGrains (); } Int grain = 0; Scanner Keyboard = New Scanner (System.in); System.out.println ("How many days the program will run? Enter the number between 1 and 64"); Int k = keyboard.nextInt (); Private Milltotalgrain (K, cereals); {K = K-1; Grain = grain * 2; Do {getTotalGrains (K, Grains); } While (k == 1); {System.out.println (grain + "grain of rice."); } While (K & lt; 1); {System.out.println ("Invalid number please try again."); } While (k> 64); {System.out.println ("Invalid number please try again."); }}}}}

First of all, there is nothing here

There are several syntax errors in your code, take a look at the following section. 

  Private getTotalGrains (K, Grains); << code>  
     
  1.  Return type is missing  
  2.  parameter types are missing  
  3.  after definition of method in ;  is unnecessary   
     It should be rewritten:  
      Private zero getTotalGrains (int k, int grains) { < / Pre> 
     In addition to this, you try to define the method within  getTotalGrains  method  main  which is not supported by Java  
     I think That there are other mistakes besides

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] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
