(a) Write the output of the following Java program fragment, assuming that Scanner has

been properly imported. When prompted, the user enters the following: 1 2 3 4

System.out.print ("Enter four integers: ");

Scanner stdin = new Scanner(System.in);

int num1 = stdin.nextInt ( );

int num2 = stdin.nextInt ( );

int num3 = stdin.nextInt ( );

int num4 = stdin.nextInt ( );

int result;

result = (num1 + num2 + num3 + num4);

System.out.print ("The result is: ");

System.out.println (result);

(b) Write out the changes you would make to above Java program segment to print the average of the four input numbers (Reminder: int division results in losing fractional part)
