How to solve Below is a partial code for a class followed by the output that would be displayed on the screen when we run the class:

CODE:

public class Decision $\{$

$//$ Given a monthNum number: $1$ to $12,$ this method returns the season as a String

private static String monthToSeason$($int monthNum$)\{$

String season;

if $($monthNum $<1||$ monthNum $>12)\{$

season $="$No Season: Invalid Month Number";

$\}$

else $\{$

if $($monthNum $<3||$ monthNum $>11)\{$

season $=$ "Winter";

$\}$

else $\{$

if $($monthNum $<6)\{$

season $=$ "Spring";

$\}$

else $\{$

if $($monthNum $<9)\{$

season $=$ "Summer";

$\}$

else $\{$

season $=$ "Autumn";

$\}$

$\}$

$\}$

$\}$

return season;

$\}$

$//$ This method does exactly what the above method, monthToSeason does

$//$ The only difference is that this one uses an else$-$if structure

$//$ instead of the nested if$-$else structure used in monthToSeason

private static String monthToSeason$2($int monthNum$)\{$

$//$ Your code starts here

$//$ Your code ends here

$\}$

$//$ Given a season number: $1$ to $4,$ this method returns the season as a String

private static String seasonNumToSeason$($int seasonNum$)\{$

String season;

if $($seasonNum $==1)$

season $=$ "Spring";

else if $($seasonNum $==2)$

season $=$ "Summer";

else if $($seasonNum $==3)$

season $=$ "Autumn";

else if $($seasonNum $==4)$

season $=$ "Winter";

else

season $="$No Season: Invalid Season Number";

return season;

$\}$

$//$ This method does exactly what the above method, seasonNumToSeason does

$//$ The only difference is that this one uses a case$-$switch structure

$//$ instead of the else$-$if structure used in seasonNumToSeason

private static String seasonNumToSeason$2($int seasonNum$)\{$

$//$ Your code starts here

$//$ Your code ends here

$\}$

public static void main$($String$[]$ args$)\{$

for $($int i $=0$; i $<14$; i$++)$

System.out.println$("$Month Number $="+$ i $+"$; Season $="+$

monthToSeason$2($i$))$;

for $($int i $=0$; i $<6$; i$++)$

System.out.println$("$Season Number $="+$ i $+"$; Season $="+$

seasonNumToSeason$2($i$))$;

$\}$

$\}$

OUTPUT:

Month Number $=0$; Season $=$ No Season: Invalid Month Number

Month Number $=1$; Season $=$ Winter

Month Number $=2$; Season $=$ Winter

Month Number $=3$; Season $=$ Spring

Month Number $=4$; Season $=$ Spring

Month Number $=5$; Season $=$ Spring

Month Number $=6$; Season $=$ Summer

Month Number $=7$; Season $=$ Summer

Month Number $=8$; Season $=$ Summer

Month Number $=9$; Season $=$ Autumn

Month Number $=10$; Season $=$ Autumn

Month Number $=11$; Season $=$ Autumn

Month Number $=12$; Season $=$ Winter

Month Number $=13$; Season $=$ No Season: Invalid Month Number

Season Number $=0$; Season $=$ No Season: Invalid Season Number

Season Number $=1$; Season $=$ Spring

Season Number $=2$; Season $=$ Summer

Season Number $=3$; Season $=$ Autumn

Season Number $=4$; Season $=$ Winter

Season Number $=5$; Season $=$ No Season: Invalid Season Number

INSTRUCTIONS:

Complete the code by writing the body of the body$-$less methods. Your code must go between the comments $"//$ Your code starts here" and $"//$ Your code ends here." Do not make any other modifications to the code.

Copy and paste the partial code to the answer box and complete it$.$ You may also copy it to a Java development environment, complete it$,$ and test the code. In that case, copy the completed code to the answer box after you are done testing.
