 | >insisting that the rating supplied by the user be valid This part is somewhat not sure for me (the language). Does it mean your program has to also validate the validity of the user input, or the user will always enter a valid input??? |
| | Re: Help Please :) >1.take input It means your program should prompt users for an input.

| | There are a lot of ways to do what you are explaining. It depends on how you design & layout... Some may use JQuery, but I prefer primitive JavaScript. :P Below is a simple example... <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <style type="text/css"> div.hideContent { display: none; visibility: hidden; … |
| | Hmm... Have you implemented an ajax call yet? I mean just one ajax call to replace certain data on the page. If you could do it even once, then it is easy to implement the auto-call using setTimeout() at the end of the success call portion. An example of ajax … |
| | What is line 28??? If you want to use the onchange event, you need to put/attach the event to the *select* tag. To me, it looks like the code line is hanging inside, not one of the property of the *select* tag... //i.e. <select id="blah" name="dbl_blah" onchange="ChangIt('arg1')"> ... </select> |
| | Don't think the OP is adding an iframe element to the form, but adding it to the form's parent element. But your suggestion is valid that using getElementById() function to obtain the element from the DOM. Anyway, back to the OP... Do you have a form tag name "form"? |

| | Re: java Huh? This is JavaScript forum. You should go to [this forum](http://www.daniweb.com/software-development/java/9) instead. To answer your question, it said that you to create 2 String variables. Assign the value "COMPUTER PROGRAMMING" to the first one, and then iterate through a loop using the first variable length in reverse order. Inside the … |

| | There are couple mistakes in your code... 1) When you said first 2 rows, in array data type, it means 0 & 1 indices because array uses 0 index (value from 0 up to array_length-1). In your code, line 17 for example, is going through 0, 1, and 2 which … |
| | You are on the right track. You attempt to check for digit number using indexOf() method which is wrong. In your loop, get rid of indexOf() method but use charAt(i) instead. The returned value of the charAt() method is a char which could directly be compared (using == symbol) with … |

| | If you want to keep asking for playing again, you need another loop around it. Either let users get out of the loop by saying 'n' or not equal to 'y' is your choice. You already know how to use while-loop in your case. You could simply add another while-loop … |
| | Do you know the value of the current rotation angle of the image when space is being pressed? If you could obtain such value, you can simply compute the point by doing the [point rotation](http://en.wikipedia.org/wiki/Rotation_%28mathematics%29) using the center of the image as the origin point. |
| | I see no problem with adding unlimited button to a panel and let it extend down the display while you can still scroll down. However, too many buttons may cause you problem, so you may need to redesign the layout of what you are doing. So could you please show … |
 | Wouldn't this part ry=Math.floor(Math.random()*myimages.length) if (ry==0) { ry=1 } is equivalent to... ry=Math.ceil(Math.random()*myimages.length) *Edit:* Wait... My bad... The former gives higher propability (twice as high as others) to the first image (1) and not select the last image (6), but the latter gives equal propability to each image including the … |

| | Not going to look at your code. Will answer from the header... To do that, you just need to check whether or not the new element (text field) has been added to the page. If it already exists, don't add a new one. A simple way to check is to …  |
| | Line 34, you are returning *roll* variable but you didn't have anything to do with the variable inside the method. The method is supposed to build up a String and return it? |
| | You will have a hard time finding all of them. You have both missing and extra curly bracket. The first one is inside your scene2() method. if(choice2.equalsIgnoreCase("FIGHT")) { //User fights if(sword == true || axe == true) { //If the user has a weapon System.out.println("It seems that you have a … |
| | \#1 You are correct if and only if the question is not about writing a program. In other words, true && true is the same as (true || false OR false || true) in programming. The question ask which expression is true and that is ambiguous to me. \#2 Two … |
| | If you are using an array already, you could do a sort and get the index in the middle for splitting as well. The algorithm has bigger Big O and a bit more complex but requires less space use in the process. |

| | There are a couple problems in your code. 1) Line 19, you do NOT need a for loop to check the existence of a substring inside a string. The only occasion you need a loop is when you check each character of a string one by one. 2) Line 21, … |
| | How did you enter when the question shows up? Do you understand what nextInt() mean? When you use nextInt(), the input is expected to be an integer (i.e. 234, 123), not a decimal number (i.e. 25.45, 100.0). If your input is not followed the integer format, you will get an … |
