If

Here is the next Java program you'll enter, which introduces you to the if statement. Type this in, make it run exactly right and then we'll see if your practice has paid off.

The if statement helps us make decisions and control program flow. In the program below, only one line prints but there are 7 System.out.print statements. The if statement ensures that only the correct one is executed.

Hurricane wind speed chart

public class Hurricane {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.print("How fast was the wind blowing?" );
        int windSpeed = scan.nextInt();

        if (windSpeed <  65) 
            System.out.println("It was not a hurricane");
        else if (windSpeed <  96) 
            System.out.println("It was a class 1 hurricane");      
        else if (windSpeed < 111) 
            System.out.println("It was a class 2 hurricane");      
        else if (windSpeed < 131) 
            System.out.println("It was a class 3 hurricane");      
        else if (windSpeed < 155) 
            System.out.println("It was a class 4 hurricane");      
        else
            System.out.println("It was a class 5 hurricane");

    }
}

Your assignment

Write a program to accept an integer from the user. The program should print the integer or 'Fizz','Buzz' or 'FizzBuzz'. For numbers 1 through 100, if the number is divisible by 3 print Fizz. If the number is divisible by 5 print Buzz. If the number is divisible by both 3 and 5 (15) print FizzBuzz. Otherwise print the number.
