aqikhya.neelwmSuppose that the text file on the Web http://cs.armstrong.edu/liang/data/Scores.txt contains an unspecified number of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks.
In a triangle, the sum of any two sides is greater than the other side. Create an IllegalTriangleException class. Write a Triangle Class with the constructor of the Triangle class designed to throw an IllegalTriangleException object if a triangle is created with sides that violate the rule, as follows:
/** Construct a triangle with the specified sides */
public Triangle(double side1, double side2, double side3) {
throws IllegalTriangleException
// Implement it
}
(Plot functions using abstract methods) Write an abstract class that draws the diagram for a function. The class is defined as follows:
abstract class AbstractDrawFunction extends JPanel {
/** Polygon to hold the points */
private Polygon p = new Polygon();
final int TO_X_AXIS = 125;
final int TO_Y_AXIS = 125;
final int END_OF_X_AXIS = 275;
final int END_OF_Y_AXIS = 200;
protected AbstractDrawFunction () {
drawFunction();
setBackground(Color.white);
}
/** Return the y-coordinate */
abstract double f(double x);
/** Obtain points for x-coordinates 100, 101, . . ., 300 */
public void drawFunction() {
for (int x = -100; x <= 100; x++) {
p.addPoint(x + TO_Y_AXIS, TO_X_AXIS - (int)f(x));
}
}
@Override /** Draw axes, labels, and connect points */
protected void paintComponent(Graphics g) {
super.paintComponent(g);
// Draw x axis
g.drawLine(10, TO_X_AXIS, END_OF_X_AXIS, TO_X_AXIS);
// Draw y axis
g.drawLine(TO_Y_AXIS, 30, TO_Y_AXIS, END_OF_Y_AXIS);
// Draw arrows on x axis
g.drawLine(END_OF_X_AXIS, TO_X_AXIS, END_OF_X_AXIS - 20, TO_X_AXIS - 10);
g.drawLine(END_OF_X_AXIS, TO_X_AXIS, END_OF_X_AXIS - 20, TO_X_AXIS + 10);
// Draw arrows on y axis
g.drawLine(TO_Y_AXIS, 30, TO_Y_AXIS - 10, 50);
g.drawLine(TO_Y_AXIS, 30, TO_Y_AXIS + 10, 50);
// Draw x, y
g.drawString("X", END_OF_X_AXIS - 20, TO_X_AXIS - 30);
g.drawString("Y", TO_Y_AXIS + 20, 40);
// Draw a polygon line by connecting the points in the polygon
g.drawPolyline(p.xpoints, p.ypoints, p.npoints);
}
}
public class draw_graph extends JFrame {
public static void main(String[] arg) {
draw_graph dg = new draw_graph();
dg.setSize(400,400);
dg.setTitle("Graph");
dg.setLocationRelativeTo(null);
dg.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
dg.setVisible(true);
}
draw_graph () {
setLayout(new GridLayout(1, 3, 1, 1));
// Create your derived class object here
}
}
Test the class with the following functions defined in concrete classes:
a. f(x) = x*x;
b. f(x) = sin(x);
c. f(x) = cos(x);
d. f(x) = tan(x);
e. f(x) = cos(x) + 5*sin(x);
f. f(x) = 5*cos(x) + sin(x);o
g. f(x) = log(x) + x*x;
For each function, create a class that extends the AbstractDrawFunction
class and implements the f method.
Your output should consist of screen shots of plots for these functions with the label of the plot as your name_idnumber.
