View Replies View RelatedCalling File From Directory In Java Program
Nov 26, 2014I don't really understand the question is the thing. Its about calling a file in the java program. I read the book and i can see how to call a file from a directory and how to save it and edit it but I don't understand what the instructor is asking for. Mostly what files need called and println.
Assuming the object that manages output will be called writer, write a statement that opens a text file called home.html for output by println statements.
To be file-writable and file-readable, an object must be an instance of a class that implements___________.
Write a statemnt that opens a file for input of objects and assigns a reference to the connection to ObjectIn. Assume the file is in the current directory, with the name automobiles. data.
How To Install Java In Linux
Apr 5, 2014I am trying to install Java on my Debain based Linux OS and can`t seen to figure it out. I first typed "chmod +x jdk-8-nb-8-linux-i586.sh", than typed "./ jdk-8-nb-8-linux-i586.sh" to install it. It started to install, but than it gave my this message: (computer name has been changed)
bobsmith@bobsmiht-OptiPlex-GX620:~/Downloads$ ./jdk-8-nb-8-linux-i586.sh
Configuring the installer...
Searching for JVM on the system...
Preparing bundled JVM ...

Cannot prepare bundled JVM to run the installer.
Most probably the bundled JVM is not compatible with the current platform.
How do I fix this? My Linux computer is not connected to the internet, I don`t know if this is a problem or not.
How To Install Java 8 On Ubuntu 14.04
Apr 19, 2014I used Ubuntu 13.10 on a Chromebook and Java7 and Java8 both worked nicely. Not on Ubuntu14.04, however.
I can try
sudo apt-get install openjdk-7-jdk
javac -version
java -version
… and it tells me 1.7.0_51 IcedTea etc. I haven't found an OpenJDK version of Java8, so I tried the usual technique of unzipping the Oracle download into /usr/java (which I have created and given “campbell” ownership of).
campbell@xxxxx:~$ /usr/java/jdk1.8.0_05/bin/java -version
bash: /usr/java/jdk1.8.0_05/bin/java: cannot execute binary file: Exec format error
campbell@xxxxx:~$ /usr/java/jdk1.7.0_55/bin/java -version
bash: /usr/java/jdk1.7.0_55/bin/java: No such file or directory
Same download in my home directory as I had last week. I repeated the download and got the same error. It is different from the error for Oracle Java7, which I haven't actually got installed at the moment.
I shall probably revert to Ubuntu13.10 for a bit.
How Registry Can Look Before Java Install - Keyword
Dec 2, 2014I am attaching a document which shows the current state of my registry.What I want to know is if I can [safely] delete the JavaSoft folder with all lower subfolders, then re-install jdk1.6/0_31 which, I am told, is the current version being used here by developers.According to others on the development team (not my team), there COULD be something in the registry that is preventing both the installation of java jdk AND its uninstallation.Since I cannot seem to attach any kind of document.

Enterprise JavaBeans :: Virtual Machine Has Aborted Error During Java EE SDK Install
Aug 5, 2014I'm trying to install java_ee_sdk-6u3-jdk7-windows-x64.exe on our new Windows Server 2012 machine but the installer starts and I then get a Setup box appear that says Error: The Java(TM) Virtual Machine has aborted. I've looked in the Event Viewer and there are no messages and I've tried to get the installer to create a log file (by passing the parameter -l <loglocation>) but it doesn't seem to get that far as no log is created.
The very first time I tried to run the JavaEE install on this machine, it installed everything ok but didn't create the windows service as .NET Framework 3.5 was missing. So I uninstalled JavaEE and added in the .NET Framework 3.5 and then my problems began. I have already installed these versions of Java and JavaEE successfully on a previous Windows Server 2012 machine which had the .NET Framework 3.5 on it.
The JRE installed already on the computer is jre-6u45-windows-x64.exe and I am logged in as an administrator. I've tried uninstalling the JRE and reinstalling and also doing a registry clean using CCleaner incase there are any old references to the JRE/JavaEE but it didn't work.
Write Interface Directory To Manipulate Entries In Telephone Directory
Mar 12, 2014this is the following task i am trying to do. Write an interface Directory to manipulate entries in a telephone directory for the University. The interface must support the following operations:
1) The ability to insert new entries into the directory. Entries should be stored in alphabetical order of surname.
2) Delete entries from the directory either by name or number
3) Provide a lookup method that will find the extension no of a member of staff given
his/her name. You should try to make this method run as efficiently as possible.
4) Change a person's telephone number
5) Print the telephone directory in a neatly tabulated fashion.
Write a class ArrayDirectory that implements this interface using an array to store the telephone directory information. The class must store the surname and initial for each member of staff and their telephone extension (a four digit number which may start with a zero). You may find it useful to define a class Entry to store information about individual entries. The entries should be read into the array from a text file consisting of multiple lines in the following format:
Surname<tab>Initials<tab>Telephone extension
The part that i am stuck on is trying to do the entry method, delete entries method, loop up method, change persons telephone number and be able to print it.

Servlets :: Url Pattern - Real Directory Vs Virtual Directory
May 26, 2014Consider the url-pattern:
<url-pattern> /Beer/* </url-pattern>
The web app structure is: -

My book says that /Beer/* can be a real or a virtual directory. What is the difference between the two and how do I create a virtual directory in tomcat ?

I am trying it by

props.load(in);
in.close();
FileOutputStream out = new FileOutputStream(newprop.properties);
props.setProperty("myDirectory","C:Lisa estUpdate" );

Extra comes before :.
How can I remove that.
