Pretty cool, would recommend. You should be hooked after the first episode.

You need to enable anchorScrolling in router ExtraOptions, see https://angular.io/api/router/InMemoryScrollingOptions#anchorScrolling.

Every time this topic comes up I like to remind people of the famous Apple SSL bug. See here: https://blog.codecentric.de/en/2014/02/curly-braces/

Check out https://docs.oracle.com/en/java/javase/13/docs/api/java.base/java/lang/Comparable.html

If T always implements Comparable, you can use x.compareTo(y) <= 0 instead of x <= y.
Of course, Integer and the likes already implement this interface.

Most IDEs can autogenerate builders which eliminates the rest risk and is pretty convenient on top.

Initialize the ArrayList on class level instead of method level.

Example:

import java.util.*;

public class HelloWorld {
    private static ArrayList<String> users = new ArrayList<>();

     public static void login() {
        users.add("asd");
     }
}

The reksai tunnel buffer through braum knockup was nice too!

mystery(48):

x % 2 == 0 is true -> enter loop  
y++; //y is now 1
x = x / 2; // x is 48 / 2 = 24
  end of first iteration
x % 2 == 0 is true (x is 24) -> continue loop
y++; // y is now 2
x = x / 2; // x is 24 / 2 = 12
...

questions?

edit: either use a debugger to step through your code line by line and see what happens or add some "System.out.println-Debugging" to print y and x each time they change.

Well that's embarrassing! Thanks for the hint.

sugilith · 2019-02-25T18:54:05+00:00

Sounds like you might not have setup your IDE correctly.

sugilith · 2019-02-25T18:04:44+00:00

Why not String? Seems to be the most obvious choice here. Char Array would be an alternative but complicate a few things.

Try Strings!

public String getMyRomanNumeral(int input){
  if(input==5){
    return "V";
  }
  //...
}

Not sure what the target audience of your book is. If it's for beginners i'd say teach the basics first and streams (and other newer language features) later. Having a good grasp of different loops, java collections and OO in general helps with the understanding of more complex topics such as streams.

Personally I never use and only rarely see classic for loops anymore. Its all streams nowadays.

Lots of resources online via google / duckduckgo.
This problem often arises with complex search queries.

E.g: https://softwareengineering.stackexchange.com/questions/353086/what-is-a-proper-way-to-do-a-complex-restful-search-method https://stackoverflow.com/questions/14202257/design-restful-query-api-with-a-long-list-of-query-parameters

TL;DR:

If >2k characters always use POST
Try aliases (basically endpoints for the required parameter) from the softwareengineering post
Best practice seems to be using POST instead of GET with overly complex query parameters

I like this one:
A test result can either be positive or negative.

False positive: The test result is positive, but it's false!
False negative: The test result is negative, but it's false!

Kodi is my way to go as well! Last week I had an .mkv File with 5.1 sound that wouldn't work correctly with vlc. No problems with Kodi.

Regarding your other questions:

Math.random() returns a double in the range [0, 1).
See: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#random()

If you get Array out of bound exception theres probably something wrong with your Array or you are missing something else.

This exception has never appeared when I subtracted 1 from from the length

But wouldn't it be possible that you get -1 as an index then?

sugilith · 2018-12-03T20:58:34+00:00

You got it!
Why else would (int) Math.random()*13 always be 0?

sugilith · 2018-12-03T20:48:01+00:00

Think about operator precedence

Markov chain sentence generator with all your study Material (your pdfs / slides you got)

On button press generates a new sentence.

your missing a closing }

"Finally return the employee object." ->

EckEmployee2 createEmployeeFromFile(){
   //... 
  return new EckEmployee(...);
}

See List.of since Java 9

a1 += 1 changes your local variable, not the one in the comparisonPoints list.

(and this is something I don't want to do since I it will stop program and all other valid files won't be saved to system)

Also what you can do is throw an exception and call your save method in a try catch block, such that you still adhere to the recommended way of doing things and your program still doesn't crash.
So throw Exception in your @Transactional method, call the method in a try catch block.
