This program inputs three numbers from a user, calculates the sum of the numbers, and prints the answer. Match the items below based on the following code. Assume that the user enters a $10$ for the first number, a $20$ for the second number and a $30$ for the third number:

public class sumThreeNums

$\{$

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

$\{$

$//$ Create a Scanner object

Scanner input $=$ new Scanner$($

System.in$)$;

$//$ Prompt the user to enter three numbers

System.out.print$("$Enter three numbers: $")$;

double number$1=$ input, nextDouble$()$;

double number $2=$ input, nextDouble$()$;

$//$LINE IS MISSING HERE

double sum $=$ number $1+$ number $2+$ number $3$ ;

System.out.print$("$Sum $=+$ sum$)$;

$\}$

$3.$

double number $3=$ input.nextDouble$()$;

Sum $=60\mathrm{.}0$

double sum $=$ number $1+$ number $2+$ number $3$ ;

$60$
