  • Easiest Java image processing solution

    - by Daniel Fath
    Here is the deal, in my Java project I have to make a composite document that combines both text and images; So I'm looking for a way to manipulate pictures (rotate, change size, that sort of thing). The API I'm looking for should be clear and easy to learn (preferably with some examples), it should cover the basic transformations I made above - rotate,change size, eventually crop.

  • Regarding Java String dollar to cents conversion

    - by arav
    I have a java string which has an dollar value and cents value after decimal points and starting with a + or - sign. I want to convert into cents and store it in a integer (it can have + or -). Also i need to check if the cents part (after decimal point) not more than 2 digits and throw an error message if exists example : String dollval= "12.23" ,"12","-0.09", "-99","-99.0", "-99.23","0.00" int dollint = 1223,12,-9,-99,-00,-9923,0

  • FileReader File not Found Java

    - by Lucas Camargo de Carvalho
    I have done everything I know. The file is not a ".filetype.filetype". It is in the same folder as the .settings and the other project files. Why is this not working? Full path isn't working either, but strangely, a Scanner is working. import java.io.FileReader; public class test { public static void main(String[] args) { FileReader testFileReader = new FileReader("hotels.json"); } }

    - by Alvin
    I know randomized UUID have very very very low probability for collision in theory, but I am wondering, in practice, how good is java 5's randonUUID in terms of not having collision? Does anybody have any experience to share?

  • java.net.SocketException: Software caused connection abort: socket write error

    - by npinti
    Hi guys, I am trying to send an image from a Java desktop application to a J2ME application. The problem is that I am getting this exception: java.net.SocketException: Software caused connection abort: socket write error I have looked around on the net, and although this problem is not that rare, I was unable to find a concrete solution. I am transforming the image into a byte array before transferring it. These are the methods found on the desktop application and on the J2ME respectively public void send(String ID, byte[] serverMessage) throws Exception { //Get the IP and Port of the person to which the message is to be sent. String[] connectionDetails = this.userDetails.get(ID).split(","); Socket sock = new Socket(InetAddress.getByName(connectionDetails[0]), Integer.parseInt(connectionDetails[1])); OutputStream os = sock.getOutputStream(); for (int i = 0; i < serverMessage.length; i++) { os.write((int) serverMessage[i]); } os.flush(); os.close(); sock.close(); } private void read(final StreamConnection slaveSock) { Runnable runnable = new Runnable() { public void run() { try { DataInputStream dataInputStream = slaveSock.openDataInputStream(); int inputChar; StringBuffer results = new StringBuffer(); while ( (inputChar = dataInputStream.read()) != -1) { results.append((char) inputChar); } dataInputStream.close(); slaveSock.close(); parseMessage(results.toString()); results = null; } catch(Exception e) { e.printStackTrace(); Alert alertMsg = new Alert("Error", "An error has occured while reading a message from the server:\n" + e.getMessage(), null, AlertType.ERROR); alertMsg.setTimeout(Alert.FOREVER); myDisplay.setCurrent(alertMsg, resultScreen); } } }; new Thread(runnable).start(); } I am sending the message across a LAN, and I have no problems when I send short text messages instead of images. Also, I used wireshark and it seems that the desktop application is only sending part of the message. Any help would be highly appreciated. Also, everything works on the J2ME simulator. Thanks.

  • Java Exceptions

    - by Mandar
    This may sound awkward ... But I didn't understand it. Why do we have compile-time error and not compile-time exception in java ? I mean to say that we never say compile-time exception. We tend to say it as compile-time error. Is there any specific reason for the same ?? Any suggestions are welcomed.... Thanks !

  • Eclipse/Java code completion not working

    - by Rob
    I've downloaded, unzipped and setup Eclipse 3.4.2 with some plugins (noteable, EPIC, Clearcase, QuantumDB, MisterQ). Now I find when I'm editing Java projects the code completion is not working. If I type String. and press ctrl-space a popup shows "No Default Proposals" and the status bar at the bottom shows "No completions available". Any ideas? Thanks....
