School class

There is one instance variable for this class: a List of Person references.

Use an initializer block to create an empty ArrayList and assign it to your List variable.

public void register$($Person p$)$: this method throws an IllegalPersonException if the argument is null. Otherwise, the Person is added to the end of your List.

public void printRoster$()$: this method uses a method reference to print out all the people $($i$.$e$.$ triggering a call to their respective toString$()$ methods$).$

public void printAgesAndYears$()$: this method declares a local variable w of type Writeable, which takes three parameters: fullName, yearBorn, and maxYear; for example: "Tiger Woods", $1975,2022,$ or "Albert Einstein", $1879,1955.$ It uses a lambda expression to loop through the integers from yearBorn to maxYear and prints the person's name and age for each year of life. For example $($use all the years; some were omitted here for brevity$)$:

Tiger Woods: $1975($age $0)$

Tiger Woods: $1976($age $1)$

Tiger Woods: $1977($age $2)$

Tiger Woods: $1978($age $3)$

Tiger Woods: $1979($age $4)$

Tiger Woods: $1980($age $5)$

$...$ etc $...$

Tiger Woods: $2019($age $44)$

Tiger Woods: $2020($age $45)$

Tiger Woods: $2021($age $46)$

Tiger Woods: $2022($age $47)//$ if the Person is alive, loop until the current year

Finally, loop through your List of Person references and use a lambda expression to determine the argument values to pass to w$\text{'}$s printData$()$ method $-$ fullName, yearBorn, and maxYear $$ as follows:

$1.$ fullName: the Person's getName$().$getPrettyName$()$

$2.$ yearBorn: the Person's getDateOfBirth$().$getYear$()$

$3.$ maxYear: the current year $($if alive$),$ or the Person's getDateOfDeath$().$getYear$()($if not alive$).$

Albert Einstein: $1879($age $0)$

Albert Einstein: $1880($age $1)$

Albert Einstein: $1881($age $2)$

Albert Einstein: $1882($age $3)$

$...$ etc $...$

Albert Einstein: $1953($age $74)$

Albert Einstein: $1954($age $75)$
