A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Hi, I hope I can explain this well enough.

My folder structure looks like the attached. In each folder, I have src/pages, results, dev/gulp.

pages contains the nunjucks files, results are the resulting html files from running gulp nunjucks, and dev/gulp is where the gulpfile.js is.

When I want to make a change across the board, say to the navigation, I have to use the command line to go into each folder, gulp nunjucks, upload, then back out by changing directories, navigate to the next one, gulp nunjucks, and on through all 13. So my command line looks like the attached.

Can you help me find a way to speed that up?

Below line gives error as below as        device.getInternetConnection() return enum not String.            
callableStatement.setString("InternetConnection", device.getInternetConnection());


Multiple markers at this line
      - The method getInternetConnection() is undefined for the type Device
      - The method setString(String, String) in the type CallableStatement is not applicable for the arguments (String,
       Device.getInternetConnection)


Here  device.getInternetConnection()); returns the enum  InternetConnection

      public enum InternetConnection{
            
            WIFI("08"),
            CELLULAR("06");
            
            InternetConnection(String ip){
                  this.ip = ip;
            }
            
            private final String ip;
            
            public static InternetConnection getFromIP(String ip) {
                  for(InternetConnection pc : InternetConnection.values()) {
                  if(pc.getIP().equals(ip))...
                       ......
                  }
                  throw new IllegalArgumentException("This iP: " + iP + " does not exist");
            }
            
            public String getIP() {
                  return ip;
            }
      }

How to change my callable statement setter to accommodate enum instead of string?

Hi,

I am trying to double list numbers using functionala lamda programming


http://codingbat.com/prob/p117665
Given a list of integers, return a list where each integer is multiplied by 2.

doubling([1, 2, 3]) → [2, 4, 6]
doubling([6, 8, 6, 8, -1]) → [12, 16, 12, 16, -2]
doubling([]) → []

Open in new window


Solution:

public List<Integer> doubling(List<Integer> nums) {
  nums.replaceAll(n -> n * 2);
  return nums;
  
  // OR the equivalent java streams solution:
  // return nums.stream()
  //  .map(n -> n * 2)
  //  .collect(Collectors.toList());
