New Instance of class

Question

I have two classes. In one class I have created a new instance of the other class as follows:
class1{
class2 c2 = new class2(this);
However in class2 I now want to create a new instance of class1 but I cant do this as I go into an infinite loop right. What can I do???

Answer 1

In class1 I have a JTable, with a number of colums and
each row containing data pertaining to a record. In
class2 I have a text area, comboboxes, and other such
gui items. class1 extends JFrame. class2 extends
JPanel. When the user selects a row the gui created in
class2 is added to the frame in class1 (south of
JTable)
Each time the user selects a different row, the
appropriate data (data from the row selected)is
displayed in the gui items in class2 - hence the need
for a new instance of class2 in class1.
However when the user presses the save button in the
class 2 gui I wish the data to be updated in the
class1 JTable - hence the need for a new instance of
class1 in class2. I can see the need for class2 to have a reference to the instance of class1. But it does not sound like you need or want to create a new instance of class1. class1 is a JFrame. If you pass a reference to class1 in the constructor of class2, then class2 can use the reference to the class1 instance to add, remove or otherwise update class1.
