        }

        }
        else if (txtEmail.getText().equals("")) {
            JOptionPane.showMessageDialog(rootPane, "Please fill all out fields.","Error!", JOptionPane.ERROR_MESSAGE);
        } else if (jLabel8.getText().equals("*Invalid input*")) {
            jLabel8.setText("Downpayment: Invalid input.");
 
        }   else if (txtDesign.getText().equals("")) {
            JOptionPane.showMessageDialog(rootPane, "Choose your design.","Design", JOptionPane.ERROR_MESSAGE);
       }   
        else if (txtDownpayment.getText().equals("")) {
            jLabel8.setText("Downpayment is required");
 
       }  
        else {
            JOptionPane.showMessageDialog(null, "Order Succesful.");
            model.addRow(new Object [] {txtName.getText(), txtAddress.getText(), txtContacts.getText(), txtEmail.getText()} ); 
            this.dispose();
        }

Add a method (a "setter" or "mutator" method) to the other class that contains the table to accept the data and place it in the table appropriately. Then send the data to the table:

tableClass.setDataInTable( data );

Modify the signature of the method I've suggested as needed to specify where in the table the data should be placed.

i dont really get it sir

If you don't get getters/setters (mutators/accessors) then I recommend you spend more time practicing writing classes and their interfaces to other classes. Write multiple classes that simply share data among their instances (start simple). You might research those terms, find examples, and also review encapsulation.

Good luck!
