Lesson: 74 | Month Name to Numeric Representation Conversion Utility

1. When I provide the full name of a month as input, the utility method should return the corresponding numeric representation.
2. The utility method should handle both uppercase and lowercase inputs for month names.
3. If an invalid month name or null value is provided, the utility method should return null.
4. The utility method should be accessible statically without the need to instantiate the DateUtility class.

Codes

public class DateUtility {
    
  public static Integer GetMonthInNumber(string monthInWord){  
      
        switch on monthInWord {            
            when 'January'{
                return 1;
            }
              when 'February'{
                return 2;
            }
             when 'March'{
                return 3;
            }
            when 'April'{
                return 4;
            }
            when 'May'{
                return 5;
            }
            when 'June'{
                return 6;
            }
            when 'July'{
                return 7;
            }
            when 'August'{
                return 8;
            }
            when 'September'{
                return 9;
            }
            when 'October'{
                return 10;
            }
            when 'November'{
                return 11;
            }
            when 'December'{
                return 12;
            }
            When else{
                return null;
            }
         }     
     }      
    
 
}
