The following program contains a few blanks $($A$-$E$).$ The program is supposed to perform various mathematical operations $($addition$,$ subtraction, and multiplication$)$ on two numbers. An Operation interface with a method performOperation is used, which takes two integers as parameters and returns the result as an integer. Anonymous classes are used to provide different implementations for various operations.$[2\mathrm{.}5*4=10$ marks$]$ Your program should compile and run without any errors, and it should produce the following output: Addition Result: $30$Subtraction Result: $10$Multiplication Result: $200$ Please fill in the blanks for the correct execution of the program. Java code:interface Operation $\{$ int performOperation$($int a$,$ int b$)$;$\}$ public class Main $\{$ public static void main$($String$[]$ args$)\{//$ Addition Operation Operation addOperation $=$ new Operation$()\{$ @Override public int $----$A$----($int a$,$ int b$)\{$ return a $+$ b; $\}\}$; System.out.println$("$Addition Result: $"+----$B$----(20,10))$; $//$ Subtraction Operation Operation subtractOperation $=$ new Operation$()\{$ @Override public int performOperation$($int a$,$ int b$)\{$ return a $-$ b; $\}\}$; System.out.println$(----$C$----(20,10))$; $//$ Multiplication Operation Operation multiplyOperation $=$ new Operation$()\{$ @Override public int performOperation$($int a$,$ int b$)\{$ return a $*$ b; $\}\}$; System.out.println$(----$D$----(20,10))$; $\}\}$
