        private javax.swing.JTextField jTextField2;
        private javax.swing.JTextField jTextField3;
        // End of variables declaration
    }
    at the last highlight, i cant figure out the code to tell it to randomly parse input form each of the strings above in the other highlighed area, based on if their checkbox is checked and randomly generate passwords based on the options available, i was thinking nested switch statements but im sure there is a better way to do so please help!!!

    Default Re: help with GUI password generator

    jLabel1 = new javax.swing.JLabel();
    jCheckBox1 = new javax.swing.JCheckBox();
    jCheckBox2 = new javax.swing.JCheckBox();
    jTextField1 = new javax.swing.JTextField();
    jTextField2 = new javax.swing.JTextField();
    This is why I hate GUI builders. I have no idea what those Components do or are for.
    JTextField firstName;
    JTextField lastName;
    Whereas it is obvious what those textfields are for.

    How about using some if statements?
    If uppercase checkbox is selected, randomly select an uppercase character and add it to a buffer.
    If number checkbox is selected, randomly select a number and add it to a buffer.
    etc
    At the end randomly select other characters to satisfy minimal length. Then you can shuffle the chars to produce final password.

    Why post it, if we're supposed to ignore it?
