Moin!
Bin absoluter Anfänger und muss für eine Hausarbeit was in Java coden. Hier habe ich einen JOptionPane eingesetzt um vor einer zu großen Zahl zu warnen, man kann nur das Fenster nicht wieder schließen:

Java: 
OwnPositionLatM = new JTextField();
        OwnPositionLatM.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                LatMOwn = Integer.parseInt(OwnPositionLatM.getText());
                for (LatMOwn = 0; LatMOwn < 60; ) {
            JOptionPane.showMessageDialog(null, "Please enter valid minutes", "Error ", JOptionPane.INFORMATION_MESSAGE);
               
                 

                    OwnPositionLatM.setText("");
               
                }
                            }
        });

Vielleicht hat ja jemand ne Idee....

Hier ist sonst auch der komplette code (bei weitem noch nicht fertig):
