 | Sandeep: Nice try, but SIX YEARS too late. |
 | OK, looks like the answers array is `[student][answers]`. The correctA array seems clear enough. The student array seems pointless. Perhaps you can explain? Before writing a single line of code get some paper and a pen and work out the correct output for the first two or three students. Remember … |
 | I had the same symptoms with an SSD that died. It seems the 250Meg was the buffer size in the drive controller and when the drive itself fails all the sytem can see is the buffer. RMA time IMHO. |
| | Re: JList in a class Not sure why that code isn't working, but then I don't like the way you have forced the scroll pane into a class that should just be a list.

| | Why 2 parameters? Isn't there just one (the amount to be split)? If so you may be worrying about returning 2 values from each call, in which case: 1. You could package the two values into an array, tuple, trivial class etc depending on your chosen language 2. You only … |
| | The obvious JavaFX way to display a ResultSet is a TableView. You will find lots of examples with a quick Google, such as this one from GitHub https://github.com/seifallah/Dynamic-TableView--Java-Fx-2.0-/blob/master/DynamicTable.java |

 | There are quite a few programs that will burn a video file into a standard DVD, but the process is tedious and slow. Why not get a ChromeCast or equivalent and beam the video directly from the pc to the tv? |
| | One is implemented in hardware, the other in software! Other differences follow from that, eg one is probably faster, but the other may be easier to update or fix. ps: Next time, please do not hijack someone else's old topic - start your own new topic with a suitable title.  |
| | At a quick look it seems that all the cells in Col 0 share exactly the same renderer and editor , so they should all look exactly the same all the time! |
 | When you write the new Person to the output file you replace/overwrite the previous contents of the file, so the file only ever contains the last Person. You can't simply append to the file because an object file has a header, so you end up with multiple headers scattered through … |

 | > I should use == operator to compare the equality of two strings Hopefully that's just a slip of the keyboard, but just in case... Yes, use `==` to test for equality ( `=` is assignment). `==` works exactly as you would expect for primtives (int, boolean, char etc) but …  |

 | > I see rare symbols next to the texts Maybe the file is not text, but a binary fle of text strings, eg text: `Hello<CR>World<CR>` bin: `<fieldID=1, length= 5>Hello<fieldID=1, length= 5>World` (where the <> stuff is stored as binary integers) ... in which case editing with a text editor will …  |
 | Leaving aside al the Sci-Fi stuff, we are already facing a total collapse of society as we know it. Waves of automation, starting in agriculture, then factories, then offices, then services, now via AI in skilled services, have displaced humans from employment.

 | Re: Java AWT AWT was replaced nearly 20 years ago! You should be using Swing, or JavaFX. Swing was the direct replacement for AWT, and is very similar. JavaFX is the newest GUI and is supposed to replace Swing, but it’s very different to work with, so most people are still using Swing. … |

 | Congratulations on a really interesting question! *maybe* what’s going on is in the String.format you process a l-r string, then a r-l and after that the direction is still r-l when the third argument is processed. There are Unicode chars to override the direction, but more than that I don’t … |
 | Definitely better. Pseudo-cde is for explaining algorithms, flow of control etc, so you don't need quite so much detail, and you can make up you own "syntax", eg: GET passenger photo get eye color from photo (one of blue. brown, green, unknown) get hair color from photo (one of etc … |
