import java.util.Scanner;
public class U2_L3_Activity_Four {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a sentence.");
String sent = scan.nextLine();
int count = 0;
for (int i = 0; i < sent.length(); i++){
char c = sent.charAt(i);
if (c != ' '){
count++;
}
else{
break;
}
}
System.out.println("The first word is " + count +" letters long");
}
}
We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!
Answer:
MOD
Explanation:
MOD audio file format is primarily used to represent music. It uses the .MOD file extension and has had popularity as background music for independent video games. It would be safe to say that MOD audio file extensions are the most widespread trackers that were used and are still being used in many computer games and demos.
Answer:
Explanation:
public class Temperature
{
double ftemp;
public int Constructor(double fahrenheit)
{
ftemp = fahrenheit;
return Convert.ToInt32(ftemp);
}
public void setFahrenheit(double fahrenheit)
{
ftemp = fahrenheit;
}
public void getFahrenheit()
{
ftemp = Constructor(ftemp);
}
public void getCelcius()
{
ftemp = (ftemp - 32) * 5 / 9;
}
public void getKelvin()
{
ftemp = (ftemp - 32) * 5 / 9 + 273.15;
}
}
Answer:
1)
officeAC = new AirConditioner();
officeAC.turnOn();
2)
officeAC = new AirConditioner();
officeAC.turnOn();
officeAC.setTemp(69);
Explanation:
1)
In the first statement a new object of the class AirConditioner whose reference is assigned to the officeAC. new is a keyword which creates an object of the class.
Next statement uses the method turnOn(). Reference to the new object officeAC is used to invoke this method turnOn().
2) The first two statements works the same as in 1)
The last statement invokes a method setTemp() using the reference variable and passes the value 69 to this method to set the desired temperature.
Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
