- Suppose that the input is 39 21 15 60 150 120. What is the output of the following code? Assume all variables are properly declared. Show your trace.
Scanner keyboard = new Scanner(System.in); // Create a Scanner object to read input
(“Enter 6 integers: ”); // inform user to input 6 integers
sum = 0;
for(int b=1; b < 4; b++)
{
System.out.println(“Enter number ” +b + “:”);
n = keyboard.nextInt();
sum += n; // sum = sum + n
}
System.out.println(“Sum is ” + sum + “, last input is ” + n + “ and b value is ” + b + “.”);
