    Default importing class files :S

    Greetings to all who read this, i am completely new to java and have a problem with importing my own class file.

    My main page is this:

     
    import ConCLOCK;
     
    public class Time
    {
    	public static void main(String[] args)
    	{
    		ConCLOCK Clock1 = new ConCLOCK (0,15,2); 
    		Clock1.ConMINUTES();
    		Clock1.ConHOURS();
    		Clock1.ConTOTAL();
     
     
    	}
    }

    the imported file is this :

     
    public class ConCLOCK
    {
    	private long seconds;
    	private long minutes;
    	private long hours;
    	private long totalSEC;
     
     
     
    	public ConCLOCK ( long secs, long mins, long hrs)
    	{
    		seconds = secs;
    		minutes = mins;
    		hours = hrs;
    	}
     
    //converts minutes into seconds	
    	public  long ConMINUTES ()
    	{
    		if (minutes > 0) 
    		{
    			minutes = (minutes * 60);
    		}
    		return minutes;
    	}
     
    //converts hours into minutes then seconds	
    	public long ConHOURS ()
    	{
    		if (hours > 0 )
    		{
    			hours = (hours * 60) * 60;
    		}
    		return hours;
    	}
     
    	public void ConTOTAL () 
    	{
    		totalSEC = (seconds + minutes + hours);
    		System.out.println ( "Total time conversion to seconds is : " + totalSEC );
    	}
    }

    I am compiling from cmd prompt and not from eclipse or anything like that. I have two compiling errors that say that I need to add a "." and a ";" at the word ConCLOCK of line one right after import. My ultimate goal is to package the two class files. I am completely stumped and have no experience. Any help would rock my world. thx.

    If the two classes are in the same directory, they are in the same package (see Creating and Using Packages). You only need to import if they are in different packages. If they are in the same directory, Compile ConCLOCK first, then compile your other class. If they are in different folders, you need to define a package structure and import the correct package files appropriately.

    The import statement does not "import" other files into your code. It is way to tell the compiler where to look for classes that are used in your program. It is an extension of the classpath.
