问题 I expect to have at least 183 items in my list when I query it, but sometimes the result from my extract results in items count lower than 183. My current fix supposedly pads the array in the case that the count is less than 183. if (extractArray.Count() < 183) { int arraysize= extractArray.Count(); var tempArr = new String[183 - arraysize]; List<string> itemsList = extractArray.ToList<string>(); itemsList.AddRange(tempArr); var values = itemsList.ToArray(); //-- Process the new array that is

问题 I am implementing a video steganography for my project. I came across the algorithm from here . i have tried and tested the code and the embedding part is working fine. But i encountered a problem with the readByte which is the last method in the VideoSteganography class. The method Gives ArrayIndexOutOfBoundsException . Below is the method. I pass the parameters as String fname = jTextField3.getText(); File fil = new File(fname); String password = "123456"; SteganoInformation cls = new

问题 I have this code which gives me an "Index was outside the bounds of the array". I don't know why is this happening because variable i should always be less than the length of array bla and therefore not cause this error. private void buttonDoSomething_Click(object sender, EventArgs e) { List<Thread> t = new List<Thread>(); string[] bla = textBoxBla.Lines; for (int i = 0; i < bla.Length; i++) { t.Add(new Thread (() => some_thread_funmction(bla[i]))); t[i].Start(); } } Could someone tell me how

问题 I am trying to open a writeable SQLite database with this code... public DataAdapterForServieClass open() throws SQLException { db = DBHelper.getWritableDatabase(); return this; } However I am getting the following error on the db = DBHelper.getWritableDatabase(); line... 06-10 11:58:13.995: ERROR/AndroidRuntime(548): FATAL EXCEPTION: main 06-10 11:58:13.995: ERROR/AndroidRuntime(548): java.lang.StringIndexOutOfBoundsException: index=0 length=0 06-10 11:58:13.995: ERROR/AndroidRuntime(548):

问题 noobie question.. What is the best way to check if the index of an NSArray or NSMutableArray exists. I search everywhere to no avail!! This is what I have tried: if (sections = [arr objectAtIndex:4]) { /*.....*/ } or sections = [arr objectAtIndex:4] if (sections == nil) { /*.....*/ } but both throws an "out of bounds" error not allowing me to continue (do not reply with a try catch because thats not a solution for me) Thanks in advance 回答1: if (array.count > 4) { sections = [array

问题 I want to catch and ignore and ArrayIndexOutOfBoundsException error (basically it's not something I have control over, so I need my program to keep chugging along). However my try/catch pair doesn't seem to catch the exception and ignore it. Hopefully you can pick out what I am doing wrong. The exception occurs at this line content = extractor.getTextFromPage(page); Here is my code: for(int page=1;page<=noPages;page++){ try{ System.out.println(page); content = extractor.getTextFromPage(page);

问题 I am getting an ArrayIndexOutOfBoundsException on service start up (Bean creation) when i use Java 8 features. Java 8 has been set up and has been working. The code compiles correctly. On service start, the service fails to listen to port as the beans don't get created. When i change the code (remove java 8 constructs) the service starts and everything works fine. This is the code i am using (the working code for which the service starts): for (Item itemObject : response) { if (itemObject

问题 I have completed nearly all of the java code for the perfect shuffle.

问题 I use ArrayList to store the 'shadows' for every rectangle in the level but when I iterate through the like this: for(int n = 0; n < shadows.size(); ++n){ g2d.fillPolygon(shadows.get(n)[0]); g2d.fillPolygon(shadows.get(n)[1]); g2d.fillPolygon(shadows.get(n)[2]); g2d.fillPolygon(shadows.get(n)[3]); g2d.fillPolygon(shadows.get(n)[4]); g2d.fillPolygon(shadows.get(n)[5]); } I get a java.lang.IndexOutOfBoundsException error that looks like this: Exception in thread "AWT-EventQueue-0" java.lang
