throws exception won't permit compilation

Hello, I get the general output errors;

--------------------Configuration: <Default>--------------------

public class monthTempsClient
 {
   public static void main( String [] args ) throws IOException
   {
    int belowFreezing = 0;
    int above100 = 0;
    int[] temperatures = new int [30];
    int i = 0;
    int bigChange = 0;
    File tempsFile = new File( "tempsFile.csv" );
    Scanner scan = new Scanner( tempsFile );

    while (scan.hasNext ())
    {
    temperatures[i] = scan.nextInt();
     System.out.println( "\nReading temp from file: \t\t\t" + i +
"\t\t\t" + temperatures[i] );
    i ++;
    }

    // make month
        monthTemps aprilTemps = new monthTemps ( temperatures );
        System.out.println( aprilTemps.toString( ) );

        // make another month same as first
        monthTemps marchTemps = new monthTemps( temperatures );
        System.out.println( marchTemps.toString( ) )

    // are months equal?
        if ( aprilTemps.equals( marchTemps ) )
             System.out.println( "\nThe two months have equal temps\n"
);
        else
             System.out.println( "\nThe two months do not have equal
temps\n" );

        // get temperatures
        temperatures = aprilTemps.getTemps( );
        System.out.println( "\nApril temperatures: " );
        for (i = 0; i < temperatures.length; i++)
           System.out.println( "\n " + i + " temperature: " +
temperatures[i] );

    // change month's temps
    marchTemps.setTemps( temperatures );

      // are months equal now?
      if ( aprilTemps.equals( marchTemps ) )
        System.out.println( "\nThe two months have equal temps\n" );
      else
        System.out.println( "\nThe two months have different temps\n"
);

      // get month's biggest temp change
      bigChange = marchTemps.biggestChange( );
      System.out.println( "\nThe biggest daily change is " + bigChange
);

      // how many > .300 hitters on the home team?
      belowFreezing = aprilTemps.belowFreezing( );
      System.out.println( "\n " + belowFreezing + " temps were under
freezing" );

      // how many total hits does the home team have?
      above100 = aprilTemps.above100( );
      System.out.println( "\nThe month has " + above100 + " days above
100 degrees." );
   }
}

I do have a csv file with integer values separated by commas.

Thanks.....
