Question

JAVA coding language:

Complete the howFast method that take a double parameter, speed, and prints a message based on the value of speed. These are the message that should be printed for each range of values for speed:

"slow" for values of speed less than or equal to 10.

"fast" for values of speed greater than 10 and strictly less than or equal to 50.

"very fast" for values of speed greater than 50 and strictly less than or equal to 100.

"super fast" for values of speed greater than 100 and strictly less than or equal to 150.

"too fast!" for values of speed greater than 150.

Examples:

howFast(9);

prints slow

howFast(45);

prints fast

howFast(90);

prints very fast

howFast(200);

prints too fast!

public static void howFast(double speed) {

//Write the method body code

}

Answer 1

Explanation:

Here is the code which takes the speed as a parameter and then uses the if else if conditional structure to decide what should be printed on the console based on the value of the double variable speed.

Code:

public static void howFast(double speed) {

if(speed<=10)
{
System.out.println("slow");
}
else if(speed>10 && speed<=50)
{
System.out.println("fast");
}
else if(speed>50 && speed<=100)
{
System.out.println("very fast");
}
else if(speed>100 && speed<=150)
{
System.out.println("super fast");
}
else if(speed>150)
{
System.out.println("too fast!");
}

}
