I'm working on a problem where I have to use the FileInputStream to opens a file that contains the name of a user's favorite book and then displays it.
If the file doesn't exist, then I prompt for the book title and write it to the file using FileOutputStream. This is what I have so far but I'm lost because if I put a file that exists in line 8 then it closes, but if I don't and the user puts their favorite book nothing happens. Or, as far as I can tell nothing does.

View Replies View RelatedI'm using MS Access database. What I want to do, is to get all names of my tables in database.My SQL query :
SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
is it correct? I found it in one example and didn't change anything.
I could of course execute this and check, but the problem is, that it returns ResultSet(I'm using Java), and I do not know how to manipulate this object in this situation.Cause usually ResultSet contains columns and rows, I think now I should get only bunch of String values.
I am trying to make a program where a ball moves up continuously when you press space, then begins to move down when you reach a certain point. My method for this is to have a timer, and have a method that does this: When you press space, add 10 y coords every second (using a timer), and if you reach 470 y, then begin to drop 10 y coords. I made a method to hold the keylistener, and am running that method inside the actionPerformed method which is within another class. However, since it is a method, I cannot add my keylistener to my frame in the main method.

I want to make a database and use it in my java program. I am thinking of using MS Access database, although I m not very sure, sine I will have to use this data later in the SQL database as part of C# program.
How to start to create and use MS database in java program.
I have seen in one tutorial that the steps are:
1. Install your database management system (DBMS) if needed
2.Install a JDBC driver from the vendor of your database
but I am not familiar with this. Any example, or is this above compulsory?
We have implemented SSO based on cookies.
1. user clicks the link in our app (www.app1.com) , cookie set up done (respose.addCookie)
2. request will redirect to (third party software, cant change anything)
3..Here if the SSO enabled, it will redirect to the another URL (www.issues.app1.com) .
4,Have to get the cookie(User details) set in #1 here and validate.
Its working fine .But if we change the www.app1.com to www.abc.com , SSO is not working. We cant change www.issues.app1.com.
How to share the cookie in cross domain across 3 apps ? because middle app , we dont have control over it.
class Course
{
String courseName;
}
class Entry
{
public static void main(String[] args)
{
Course c = new Course();
c.courseName="java";
System.out.println(c.courseName);
}
}
I have defined these two classes under same java project in Eclipse IDE with no package. Above two class are having default classes. class Course is also having a instance variable courseName with default access. So when we try to compile the Entry class it will give the errors while accessing the instance variable courseName on Line 6 and 7. As both the classes are having default access modifier. class Course is not visible to class Entry, then why we do not get any compilation error while creating the object of class Course on line 5?

As my requirement I am storing the image link in database and through that link I need to access the image in the webpage. For this, I am storing images in my workspace. But the problem is, since my workspace is in C drive, I dont want to store those images in workspace because of the space matter. Can I store those images outside C drive and save the link in database? After that how can I access those in webpage?
