Passing Class Reference to method

[nek thomas]

Hello People

Please suggest me the use of passing class reference in a method

Here is the sample code from class A

public Integer[] getReport(Class classname, String sql) {

And, then when it is called inside class C, it is referred to as ,

new A().getReport(B.class, "select * from Table A")

where B is another class

Please give your suggestions on this

Thanks

Nek

You want us to guess on what your code does? And why it needs a class object?

I think it's more a case of they want someone to do their homework for them. This question has been posted on other Java forums.

Thank you, Tony, for noticing that. Please, Nek Thomas, look at this FAQ.

Yes, I did post to other forums first, but after not getting suitable response I decided to post on javaranch

I don't get it. It's your code. Why don't you tell us why you need to do SQL on a Java class?

If I had to guess, maybe something related to reflection needs to be done, and it also needs some data from a DB?

Nek, you can pass a Class object to a method, there's no problem with that.
Your example is correct provided you know what you're doing.

What is your question?

I have questions about the use of passing .class as a reference anywhere. And, please give suggestions of usage of .class in java code

There are a couple of articles on reflection on java.sun.com:

Reflection API Tutorial

Advanced Language Topics: Using Java Reflection

They both have sample code using class objects.
