 | Those `pos1` and `pos2` variables are always **0** so it's constantly comparing the first two letters. Your `i` and `j` however remain unused.  |
| | This is not what they mean by Delegation Principle. Obviously no one will redesign your application to comply with OO principles for you. You can start making your application OO by implementing the first five principles (S.O.L.I.D.). * **S**ingle Responsibility Principle - *Each class should have its own responsibility.* For … |
| | In **PromotionAdapter** * The variables should be made private (also instantiating them to null is pointless, Objects will be null by default) * On line 7 you're calling `super()` for no reason. In **promotionfragment** * According to convention, classes should start with an upper case letter and be camel cased: … |
 | You could try using the old [Android Development Tools plugin](https://developer.android.com/sdk/installing/installing-adt.html) for Eclipse. It's not the official tool anymore, but at least it's an IDE. Something else that could help is testing/running the application directly on the mobile device. If I remember correctly the plugin supports hooking up your phone and …  |
| | Re: array of images You can create an array in [various ways](https://docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.html) . String[] array = new String[]{"I","did","not","read","my","textbook","and","I","don't","know","what","a","Google","is","nor","have","I","studied","line","63","outside","of","the","Netbeans","GUI-builder"}; Furthermore, it seems that most of this code was given to you (or generated by Netbeans) and that you haven't done much of it yourself. Until then I will only leave you reading material for your …  |
| | As @JamesCherrill pointed out, the add method you're using on line 101 is not the correct way to add data to a JTable. You are passing `null` as a component to `public void add(Component comp, Object constraints)`. If you read the JavaDoc of that method you will find it says … |
| | The form has no action, so it's not sending anything anywhere. You'll need a page to act as "cart" and process/validate the selected flight there. Also, do not use the deprecated and insecure `mysql` API, but instead use `PDO` or `mysqli`. You can find more information [here](http://php.net/manual/en/mysqlinfo.api.choosing.php). There's also no … |
| | You're using `JOptionPane.showMessageDialog` inside the loop, which is why you'll get a lot of dialog windows. The `input` String you defined is not being filled, so it stays blank. Replace the method calls inside the loop and store the information in `input` instead. Secondly, by using the `integer` type for … |

| | It's in the zip.  If you have a lot of different file types to work through, perhaps [Apache Tika](https://tika.apache.org/) is an alternate solution to your problem. It uses POI and many others, but combines them into a single API for mimetype detection and metadata/content extraction. Alternatively, if you're … |
| | Re: help please guys Empty the receipt String at the beginning of the actionPerformed. Each order you run by all the checked items and, if checked, append their value to the already existing String. You can set the value of a JTextArea by using its `setText()` method. You could call that at the end … |
| | Try a tool that's on a bootable drive/CD, less chance of overwriting the old files since it won't use the hard drive. There are plenty of linux options, but if you'd rather have something similar to windows you could try [UBCD4win](http://www.ubcd4win.org/index.htm) (follow instructions and burn using a different computer, then … |
| | $.ajax({ type: "POST", url: "a.php", data: postData, success: function(data){ window.open("a.php"); } }); Instead of doing something with the response you open `a.php` again but without sending any data. If you just want a different button to do the submitting you can use [submit()](http://api.jquery.com/submit/). |

 | Regardless of Entity Framework or your data model, the select query could be something like: SELECT expenseCode.ExpenseId,expenseCode.Cost,expenses.ExpenseType FROM expenseCode INNER JOIN expenses ON expenseCode.ExpenseId=expenses.Id; Which you can put in a view if you don't want to have this query in your code. Though I believe Entity Framework automatically links tables … |

| | Well according to [this very interesting](http://www.addsimplicity.com/downloads/eBaySDForum2006-11-29.pdf) presentation their DBA's gave back in 2006 even at that time they had **26 billion** SQL executions **per day**, hundreds of coders keeping the application servers running, and were *"hitting compiler limits on number of methods per class"*.

 | `$Query-bind_result` it needs a `->`, so `$Query->bind_result`. |
 | In addition to the above, be sure to check input again before sending the actual input data. There are users who, when they can't **type** what they want, will copy-paste their garbage input (with the mouse obviously, how could they **ever** press two keys at once, that's just madness). Then … |
| | Re: passing id It's unclear (to me anyway) what you mean. Do you want to move an id from one database table to another? Move a cell from one HTML table to another? And the comma separator is supposed to do what, exactly? Split the id's? |

| | Re: click You can use `pointer-events:none` in the css of that transparent div to "ensure" it won't be the target of mouse events. Ensure between air-quotes because it will depend on what's below the div. Also, it won't work in old IE (but what does). |
| | Get a random number between 0 and the amount of records using **count x rand**, then use LIMIT offset, amount. So for instance, let's say the random number is 5. `SELECT * FROM foo LIMIT 5,1` would give you the 6th row (starts at 0). You could also just select … |

 | Several things I'm noticing: You seem to be mixing JavaScript and HTML, some of it might never run. <input id="rNo" type="radio" name="YesNo" value="No" onclick="this.form.submit();"> <input id="rYes" type="radio" name="YesNo" value="Yes" onClick="location.href='http://localhost/home/calcprint.php';" Both those inputs suggest the form should be sent **as soon as** someone clicks on them.

 | Are you still in a position to change the table structure? What you are describing sounds like a one-to-many (or many-to-many) relationship between speakers and clients.
