Question 1

In a switch statement, the default case must appear last among all cases. Otherwise, it would result in a compilation error.
◦ true
◦ false

Question 2

Analyze the following code:

// Enter an integer
Scanner input = new Scanner(System.in);
int number = input.nextInt();

if (number <= 0)

System.out.println(number);

◦ If number is positive, number is displayed.
◦ System.out.println(number); must be placed inside braces.
◦ number entered from the input cannot be negative.
◦ The if statement is wrong, because it does not have the else clause.
◦ If number is zero, number is displayed.
