Fehlermeldung: )erwartete, und "keine Aussage" ;erwartet

Im völlig neuen Programmierung in java und folgenden einige grundlegende tutorials für mein selbst.
Im, der versucht zu lösen, eine Aufgabe welche mir sagt, um ein kleines Programm, wo der Benutzer eingibt in eine amonunt von Sekunden. Das Programm soll dann zurück, wie viele Stunden, Minuten und Sekunden dies ist. I cant get ridd der Fehlermeldungen. Kann jemand mir bitte helfen?
Mein code ist der folgende

import javax.swing.JOptionPane;
public class Time2
{
   public static void main( String args[] )
   {
      //Defining types of data:
      String secondstring;
      int minutes;
      int seconds;
      int hours;
      int seconds1;
      int seconds2;

      //Making inputwindow and initializing the variable sekondstring:
      secondstring = JOptionPane.showInputDialog( "Type in seconds!" );

      //Converting secondstring to type int:
      seconds = Integer.parseInt( secondstring );

      //Initializing the variables seconds, minutes and hour:
      hours = seconds / 3600;
      seconds1 = seconds % 3600;
      minutes = seconds1 / 60;
      seconds2 = seconds1 % 60;

      //Making output box:
      JOptionPane.showMessageDialog( null, "That will be " + hours "hours, " + minutes "minutes, and " + seconds2 "seconds.", "Result", JOptionPane.PLAIN_MESSAGE );

    } //End of main method.
} //End of class Time2

Bekomme ich die folgende Fehlermeldung, wenn ich versuche zu kompilieren:
