String yourUsername and integer yourAge are read from input. Complete the try block to output yourUsername followed by $"$: Registration accepted" with error checking:

If yourUsername's length is $<3$ or $>9,$ throw a runtime exception with the message "User name's length must be between $3$ and $9".$

If yourAge is $>55,$ throw a runtime exception with the message "Age must be no more than $55".$

Ex: If input is Noemi $45,$ then the output is:

Noemi: Registration accepted

Ex: If input is Wo $45,$ then the output is:

Error: User name's length must be between $3$ and $9$

Ex: If input is Noemi $70,$ then the output is:

Error: Age must be no more than $55$

Note: yourUsername.length$()$ returns the length of string yourUsername.
