    Default <No main class found>??

    Build is good but run it will not.
    Using NetBeans IDE 7.4.
    Code:
    import java.util.Scanner;

    public class FahrenheitOrCelsius
    {
    public void FdegreeOrCdegree ()
    {
    {Scanner input = new Scanner( System.in );

    int conversionType;

    do
    {
    System.out.println("1. Fahrenheit to Celsius");
    System.out.println("2. Celsius to Fahrenheit");
    System.out.println("3. None");
    System.out.println("Conversion Type: ");
    conversionType = input.nextInt();

    if (conversionType != 3)
    {
    System.out.print( "Enter Temperature to Convert: ");
    int convertTemperature = input.nextInt();

    switch ( conversionType )
    {
    case 1:
    System.out.printf( "%d Fahrenheit is %d Celsius\n",
    convertTemperature, celsius( convertTemperature ) );
    break;

    case 2:
    System.out.printf( "%d Celsius is %d Fahrenheit\n",
    convertTemperature, fahrenheit( convertTemperature ) );
    break;
    }
    }
    } while ( conversionType != 3 );
    }
    }
    public int celsius( int fahrenheitTemperature )
    {
    return ( (int) ( 5.0 / 9.0 * ( fahrenheitTemperature - 32 ) ) );
    }

    public int fahrenheit( int celsiusTemperature )
    {
    return ( (int) ( 9.0 / 5.0 * celsiusTemperature + 32 ) );
    }
    }

    It is probably something simple and I am thinking to hard...

    because you are trying to run the program but doesn't have a main method

    the main method. to be able to run a java program, it must have a main method.

    Doesn't "public void FdegreeOrCdegree ()" set my main method?
    Any suggestions?
