I would know It is possible in java language to write function. How to check the links between each class in java ?
For example
School |1 ----- 1..*| Student
Thanks for advance.
One-to-many relationships in Java is typically implemented as a List property:
class School {
private List <Student> students;
...
So to know how many students does your school have you call students.size().
I hope I understood your question correctly.
I am not sure if i understant you correctly. But! if you are looking for a way to create UML diagrams I can recomend you ObjectAId plugin for eclipse. Very easy to install and use.

I read in an online article that in java, the program file name should be same as class name. Why is that?
Also in c# i read that program file name need not be same as class name. Why?
Can someone please explain the difference?
Here is a link to the article:

A Java class file can contain multiple classes and you can name them whatever you want.
But ideally, following the best practices, it is better to write one class per file and name the file as per the name of the Class.

is there any way to search all methods in Java class with regex?
(public|protected|private|static|\s) +[\w\<\>\[\]]+\s+(\w+) *\([^\)]*\) *(\{?|[^;])
With this you can, but search before ask, because i only have used the search to find this answer ^^.
I think you're looking for reflection - see this tutorial for help. Only through reflection can you access information about loaded classes - unless you're thinking of loading in the .java file and analyzing its text.

I have several classes with the same buttons. How can I combine them into one class rather than writing them in each class?
Thanks
Make a bean class for buttons and use them using getter and setters throughout your app.
create buttons dynamically

this link will help you to implement such things..
That may solve ur problem :)
Is the functionality of your button are different? So you can inherit some classes from base main class and put your functionality in them. Or use one class and use a flag to decide what functionality you should use.

I am currently working on a project where I found this syntax:
Method m = bluetoothDevice.getClass().getMethod("createBond", (Class[]) null);
What is the purpose of "Method" class in Java and why we use it? Please elaborate with an example
Thanks in advance!
PS: I already saw the Java docs but not able to understand it.
The Method class is part of the "reflection" API which is about meta-programming. That means you can deal with structures of your program as data and process it in a java program. This allows flexible generic or abstract solutions. Method itself just represents a method in a Java class. There are other classes representing other parts of Java programs, too (e.g. Class).

I'm looking to create an application that will be used to help find a suitable University for prospective students to attend (which is based on various criteria about themselves). The application will be used by prospective students to enter details about themselves and a list of Universities will be displayed based on their profile.
I'm on the design stage (class diagram and etc) and i'm currently thinking of some Java classes I need to produce to do this. So far I've only thought of two...
University class (to hold information about Universities)
Interface class (this the GUI display)
Can someone help suggest what other class that I will need to create this application? You can suggest as many as you like.
Take every noun in your application description. Make it into a class. See if you can write a more detailed description of your app. Use those nouns as classes as well.
