    Default Help with this java code? help appreciated

    Hi there am fairly new to learning java and I would like some help on this code, thanks.

    import javax.swing.JOptionPane;
    public class time
    public static void main(String[] args)
    String time = JOptionPane.showInputDialog ("insert the current time to the nearest hour in 24 hour format");
    int realtime = Integer.parseInt(time);

    switch (realtime)
    case "<12":
    JOptionPane.showMessageDialog (null,"good morning");

    case "> 12 && < 17":

    Use the code tag please,
    anyway your cases are strings "<12" is a string and you equal it to an integer (realtime).. remove the quotes.
    and it also false to ask that way .. you have to do:
    case 1:
    case 2:
    case 3:
    case 4:
    case 12: code.
    The code will be for 1-12.

    Depends on your wills .. you can also do it with default(if none of the cases did happens then the default will).
    Anyway read about it: The switch Statement

    Might also be worth enclosing the parseInt in a try/catch block? Just in case someone doesn't enter a valid number?
