    • Inside the "try" block,
      • Get the hour and store it in a variable.
    • Catch the exception "Exception".
      • Throw the exception "InvalidFormattingException" with a message.
    • Check if the hour value is valid.
      • Throw "InvalidHourException" with a message.
    • Get the remaining string and cut off the last two characters.
    • Check if the string’s length is less than 3.
      • Throw "InvalidFormattingException" with a message.
    • Get the minutes and store it in a variable.
    • Get "am" or "pm" and store it in a variable.
    • Inside "try" block,
      • Convert the minute string to integer.
    • Catch the exception "Exception".
      • Throw "InvalidFormattingException" with a message.
    • Check if minute is less than 0 or greater than 59.

    • Check whether the string is not equal to "am" and "pm".
      • Throw "InvalidFormattingException" with a message.
    • Check if the string is equal to "am".
      • Assign "true" to "isAM".
    • Else,
      • Assign "false" to "isAM".
  • Function to produce the resultant string.
    • Append all the value to a string.
  • Define the "main ()" method.
    • Create an object for the "Scanner" class.
    • Create an object for the class "TimeOfDay".
    • Declare a variable "time".
    • Inside "try" block.
      • Get the time from the user.
      • Call the function "setTimeTo ()" by passing the time.
    • Catch the exception "InvalidFormattingException".
      • Print the message using "getMessage ()" function.
    • Catch the exception "InvalidHourException".
      • Print the message using "getMessage ()" function.
    • Catch the exception "InvalidMinuteException".
