Defining Printers Printing the Output
 1) What is the purpose of the "private int x;" declaration in the Point class?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } It is used to access the x-coordinate from outside the class. It defines a constant value for the x-coordinate. It represents the x-coordinate of a point. It initializes the x-coordinate to zero.

 2) What does the "private void setX(int xCoord)" method do?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } It prints the x-coordinate of a point. It initializes the x-coordinate to zero. It sets the value of the x-coordinate to the given argument. It retrieves the x-coordinate value.

 3) How can the value of the y-coordinate be accessed from outside the Point class?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } Using the getX() method Directly accessing the y variable Using the getY() method By creating an instance of the Driver class

 4) What is the purpose of the print() method?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } It returns the coordinates of a point as a string. It prints the coordinates of a point. It sets the coordinates of a point. It checks if the point is within a given range.

 5) What will be the output of the code?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } (2, 3) (2, 0) (3, 2) (0, 0)

 6) Can the x and y coordinates be modified directly from outside the Point class?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } Yes, by calling the print() method. Yes, by accessing the x and y variables. No, they can only be modified using the setX() and setY() methods. No, they can only be modified within the Driver class.

 7) What is the access level of the setX() method?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } public private default (package-private) protected

 8) How are the x and y coordinates initialized when a new Point object is created?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } They are initialized to 0. They are not explicitly initialized. They are initialized to -1. They are initialized to null.

 9) Can multiple Point objects have different x and y coordinates?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } Yes, each Point object can have its own unique coordinates. Only the x coordinates can be different; y coordinates are the same for all Point objects. No, all Point objects share the same coordinates. Only the y coordinates can be different; x coordinates are the same for all Point objects.

 10) What is the significance of the main() method in the Driver class?public class Point{  private int x;  private int y;  private void setX(int xCoord) {   this.x = xCoord;  }  private void setY(int yCoord) {   this.y = yCoord;  }  private int getX() {   return this.x;  }  private int getY() {   return this.y;  }  private void print() {   System.out.println("(" + this.x + "," + this.y+ ")");  } } public class Driver {  public static void main(String[]){   Point p = new Point();   p.setX(2);   p.setY(3);   p.print();  } } It initializes the x and y coordinates of a Point object. It is a constructor for the Driver class. It prints the coordinates of a Point object. It serves as the entry point for the program's execution.
