Create a Java Application in NetBeans with the following two classes.
1. A Java class College
o Use the following data fields:
College Name
College City
Number of Tracks
Number of Students
Number of Faculty
Number of Staff
o Implement an empty constructor
o Implement a full constructor
o Implement Setters and Getters (Mutators and Accessors)
o Implement SetAll() method with all data members as parameters
2. Another Java class called CollegeDemo with the main() method:
o In the main():
o Read the values of the fields of 3 colleges from a text file and for
each create a College object.
Filename: colleges.txt
IT Dubai 7 200 50 20
ENG Abudhabi 4 400 60 20
SCIENCE Sharjah 3 300 40 20
First with empty constructor then uses setters.
Second with full constructor (no need to use setters).
Last one with empty constructor and SetAll() setter.
o Display the average number of students for all the 3 colleges.
o Change the value of ‘Number of Students’ in the SCIENCE College to
500, and display the average number of students again.
here my code :
public class Demo {
private String name ;
private String city;
private String cname ;

I would like a small box to be able to enter a contacts information and I started with building it thru netbeans. Now I am thinking I should start from scratch so I understand everything. What should I do? I am having trouble making the buttons at the bottom work. All I would like to be able to do is setFrameVisible(false); but I can't seem to be able to do that without loosing the whole project not just the frame I am working on.
The buttons I am referencing are the Cancel & Accept

I'm developing an SE Java application which allows the user to view a database that I've created. I've done the data binding to a JTable but don't see any data. I've read the Derby/Java DB manual and it seems that I need to put data into this Embedded database (single table). All I want to know is how to put the data in - can I copy the files from '.netbeans-derby' folder or do I have to utilise another method?

I would like to open the serial port in the beginning of the application and then close it when the applications closes. The problem that I am having is that I created a method to open the serial port in the main function but I can not close the serial port on exit off the application. Is there away of having the serial port be setup so that all methods can access the serial port.

View Replies View RelatedI am trying to connect to Sql Server database using Oracle UCP with sqljdbc4-3.0 JDBC driver for Sql Server,with different ports and instances.
– the issue is with the port being ignored in the server string.
For example, using port 1440 connects to the default instance (which is on port 1433) rather than MSSQLINSTANCE1 which is on 1440.
Below are Server hosts used.
sql005.sqlasoftware.com (connects correctly to the default instance)
sql005.sqlasoftware.com:1440 (connects incorrectly to the default instance on port 1433)
sql005.sqlasoftware.comMSSQLINSTANCE1 (connects correctly to the named instance)

A wages calculator application is required that can determine the total cost of crew departing from the port on that day. To do this, the application reads from an itinerary text file containing each ship being loaded in the port that day, in the following format:
<ship id>
<journey id>
<l> // where <l> is the length in hours of the journey
<s> // where <s> is the number of crew for the ship for this journey
<rate> // for each s, <rate> is hourly rate of pay
Your application must calculate the total cost of the crew for each ship/journey and then compare it with a "recommended maximum journey cost" (RM) amount typed in by the user when the application is first run. If the total amount is less than or equal to RM then the details must be written to the screen and to an output text file called wagedaily.txt. If the amount is larger than RM then the results must be written to the screen only. Messages to the screen must indicate whether the crew cost is less than, equal to or larger than RM.
Your application should find the ship with the highest crew cost that is below RM and print this out as the final piece of output to the screen.
It has given me a bunch of ships and numbers to play around with in the code, here they are:

how should I do this.
