I want to display name, address and phone using print ln & a message box
JOptionPane.showMessageDialog(this, " Name " + customerName + "\n" + " Address " + customerAddress +
      "\n" + " Phone " + customerPhone);

this is how i am doing it now or
System.out.print(" Name " + customerNameText.getText() + "\n" +
                   " Address " + customerAddressText.getText() + "\n" + " Phone " + customerPhoneText.getText()); also works
but  
JoptionPane.showMessageDialog(System.out.print(" Name " + customerNameText.getText() + "\n" +
                   " Address " + customerAddressText.getText() + "\n" + " Phone " + customerPhoneText.getText()));
gives me an error      
                                           clearForm();
here iss the error
DisplayCustomer.java:103: 'void' type not allowed here

the method signature for joptionPane.showMessageDialog takes a component and a object..
you are passing neither of these..

the code needs to be changed as

JOptionPane.showMessageDialog(this, " Name " + customerName + "\n" + " Address " + customerAddress +
      "\n" + " Phone " + customerPhone);

not a system.out.println inside the method..
