 If enter is not “q”, then create an instance of the LiFiTime object passing the entry as an argument

 If no error

10%

o Print time by calling print method in LiFiTime class

 If error

o Print error message (see sample)

LiFiTime.java class

Time objects should store the time in 2 integer instance variables, hour and minute, and include a string variable to hold the error. This should be initialized with null.

LiFiTime Constructor:

 Receive time as a string

 Perform error checking to ensure time was entered in proper format to include a color (:) between the digits

 Use indexOf and substring to separate the time string into the appropriate instance variables

 Check hour to ensure is between 1 and 23

 Check minute to ensure is between 0 and 59

 If an error occurs, change the error instance variable to reflect the error (see sample)

print method:

 Include a separate method to print the date using printf to output time in digits for the hour and 2 digits for the minutes

 Print AM if before noon and PM if after noon. Do NOT print in military time

getError method:

 Include a getError method that returns the error instance variable to the print method
