How to set up a wait for input system.

Question

hi :)
gui.addClientText("Please input an ip: ");
String ip = gui.returnLastUserEntry();Basically in between the 2 lines shows above i needthe program to wait. As you can see at the moment its simply asking for an input but no waiting, its instantly assuimg 'ip' is an unassigned value.
As i write this im assuming im going to have to create a new method to give extra functionality too addClientText, in the form of waiting for a user input.
This is my addClientText method
    public void addClientText(String clientText)
        textArea.append("From Client: " + clientText + newline);
        textArea.setCaretPosition(textArea.getDocument().getLength());
    }This is my return user thingy method
    public String returnLastUserEntry()
        return text;
    }This is how it works
    public void actionPerformed(ActionEvent evt)
        text = textField.getText();
        textArea.append("From User:" + text + newline);
        textField.selectAll();
        textArea.setCaretPosition(textArea.getDocument().getLength());
    }Is there any type of wait for this method to be called before continueing command? I raelly have no idea how to continue, i can paste more code if it would help anyone help me :)
Thanks in advance.

Answer 1

i have something working now, seems i just needed to
write out the problem to realise a soloution.
        gui.addClientText("Please input an ip:
do
ip = gui.returnLastUserEntry();
while(ip == null);
gui.addClientText("Please wait for connection
nnection to be established.");was my soloution, although not ideal itll work.That doesn't work. No one would write that style of code in Java GUI programming.
Use convenience dialog like JOptionPane instead, or, write your custom modal dialog for
getting user text input, IP or whatever.
