Answer:

Exception is thrown and the file is created with 0 length.

Explanation:

While opening a file there is an error occur which shows the file does not exist that means an  exception is thrown.

And this error can be occur when the size of the file is very very low means the file is a size of 0 length. So to avoid this error we have to exceed its length from the zero length.

Answer:

Here is Automobile.java

class Automobile {   //class name

   private int ID, year, milesPerGallon, speed = 0;   // private member variables of Automobile of int type

   private String model, vinNo, make, color;   // private member variables of Automobile of String type

   public void setID(int ID){   //mutator method to set ID

      if (ID >= 0 && ID <= 9999)  // checks ID should not be negative or more than 9999

      this.ID = ID;  

     else this.ID = 0;  }  //if ID is negative or greater than 9999 then set ID to 0

   public void setModel(String model){  // mutator method to set model

       this.model = model;      }  

   public void setYear(int year){// mutator method to set year

      if (year >= 2000 && year <= 2017) //checks that year should not be earlier than 2000 or later than 2017

         this.ID = ID;

       else this.year = 0;     } //if year is less than 2000 or greater than 2017 then set year to 0

   public void setVinNo(String vinNo){  //mutator method to set vin number

       this.vinNo = vinNo;      }

   public void setMilesPerGalon(int milesPerGallon){  //mutator method to set miles per gallon

      if (milesPerGallon >= 10 && year <= 60)  //checks that miles per gallon should not be less than 10 or more than 60

          this.milesPerGallon = milesPerGallon;

      else this.milesPerGallon = 0;      } //if it is more than 60 or less than 10 then set miles per gallon to 0

   public void setSpeed(int speed){ //mutator method to set speed

       this.speed = speed;      }

   public void setMake(String make){  //mutator method to set make

       this.make = make;    }

   public void setColor(String color){  //mutator method to set color

       this.color = color;    }

   public int getID() //accessor method to get or access ID

   {return ID;} //returns the current ID

   public String getModel() //accessor method to get or access model

   {return model;} //returns the current model

   public int getYear()// accessor method to get or access year

   {return year;} //returns the current year

   public String getVinNo() // accessor method to get or access vin number

   {return vinNo;} //returns the current vin number

   public int getMilesPerGallon() //accessor method to get or access miles per gallon

   {return milesPerGallon;} //returns the current miles per gallon

   public int getSpeed() //accessor method to get or access speed

   {return speed;} //returns the current speed

   public String getMake() //accessor method to get or access make

   {return make;} //returns the current make

   public String getColor() //accessor method to get or access color

   {return color;}    //returns the current color

  public int Accelerate() {  //method that increase speed by 5

      setSpeed(speed + 5); //calls set speed to add 5 to the speed field

      return speed;    } //returns the speed after increasing 5

  public int Brake() { //method that decreases speed by 5

      setSpeed(speed - 5);//calls set speed to subtract 5 from the speed field

      return speed;    } //returns the speed after decreasing 5

  public int Accelerate(int spd) {  //overloading methods for Accelerate()that accepts a single parameter spd

      setSpeed(speed + spd);  //increases speed up to specified value of spd

      return speed;    }

  public int Brake(int spd) {  //overloading methods for Brake()that accepts a single parameter spd

      setSpeed(speed - spd); //decreases speed up to specified value of spd

      return speed;    }

   public Automobile(int ID, String make, String model, int year, String vinNo, int milesPerGallon, int speed, String color){  //constructor  that accepts arguments for each field value and uses the set methods to assign the values

      setID(ID);  

      setModel(model);  

      setYear(year);  

      setVinNo(vinNo);

      setMilesPerGalon(milesPerGallon);  

      setSpeed(speed);  

      setMake(make);  

      setColor(color);      } }

Explanation:

Here is TestAutomobiles.java

public class TestAutomobiles {   //class name

  public static void main(String args[]) {  //start of main method

    Automobile auto = new Automobile(123, "ABC", "XYZ", 2010, "MMM", 30, 150, "White");   //creates an object of Automobile class and calls its constructor passing the values for each of the fields

 System.out.println("Initial Speed: " + auto.getSpeed());  //calls getSpeed method to get the current speed using object auto. The current speed is 150

 System.out.println("Speed after applying acceleration: " + auto.Accelerate());   //calls Accelerate() method to increase the current speed to 5

 System.out.println("Speed after applying brake: " + auto.Brake());  //calls Brake() method to decrease the current speed to 5

   System.out.println("Speed after applying acceleration: " + auto.Accelerate(180));  //calls overloading Accelerate() method to increase the current speed to 180

     System.out.println("Speed after applying brake: " + auto.Brake(50));     }  } //calls overloading Brake() method to decrease the current speed to 50

//The screenshot of the output of the program is attached.

Answer: B.  PDF

Explanation:

Portable Document Format (PDF) is such an important document that it is considered the international standard for information and document exchange. It is used for letters, resumes and even electronic contracts.

PDF was developed by Adobe to make it independent of the device or application it is being viewed on and combines layers of information into one layer thereby making it a flat document.

professor190 [17]
The definition according to google and the dictionary of technological singularity is the following : The technological singularity (also, simply, the singularity) is the hypothesis that the invention of artificial superintelligence will abruptly trigger runaway technological growth, resulting in unfathomable changes to human civilization.

The dangers this brings to man kind is the fact that people will turn out to not be people or there may be a different species considered as humans or human kind .Also we were made as humans from something else artificial super intelligence will basically be forming from us which means it will be forming from something that was already mean basically meaning there will be something changed within the species or artificial super intelligence itself.
