Assigning a java class to an identical one with different namespace

[baran tamer]

Hello ,
I would like to something unordinary i guess.
I have 2 classes which are identical to each other

 public class book {
    private int fieldA;
    private String fieldB;

    public int getFieldA() {
        return fieldA;
    }

    public void setFieldA(int fieldA) {
        this.fieldA = fieldA;
    }

    public String getFieldB() {
        return fieldB;
    }

    public void setFieldB(String fieldB) {
        this.fieldB = fieldB;
    }
    
    
}

 public class magazine  {
    private int fieldA;
    private String fieldB;

    public int getFieldA() {
        return fieldA;
    }

    public void setFieldA(int fieldA) {
        this.fieldA = fieldA;
    }

    public String getFieldB() {
        return fieldB;
    }

    public void setFieldB(String fieldB) {
        this.fieldB = fieldB;
    }
    
    
}

i would like to assign fields of class book to fields of class magazine.
I can use something like if i know the field names

 magazine.setFieldB(book.getFieldB);   

But in my case i dont know the number of fields and field names of the classes , how can i do an assignment like this generically ?

Thanks

I think you want to be able to copy values of arbitrary number of properties from one class to another. That is possible through reflection. Look at this tutorial and try to create a program that suits your requirements...

Why do you keep two different classes to begin with? Have you considered using just one class that has a boolean (or whatever is appropriate) differentiator between books and magazines?

This may help: Dozer. It's a framework for JavaBeans mapping - can map any class to any class basing on properties' names. Very easy to use.

dozer does the trick , thanks
