Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

Question

utogwVUfWNJvmW7MGwYrTyRrJDu-ioEw19ELum82_RuHi-A/formResponse?pli=1
Consider a grade-averaging scheme in which the final average of a student's scores is computed differently
from the traditional average if the student has completed a make-up assignment: drop the lowest score and
compute the new average.
The following table shows several example scores and how they would be average using the scheme
described above.
Student Scores
Make-Up Completed?
Final Average
50, 50, 20, 80, 53
No
(50 + 50 + 20 + 80 + 53)/5.0 = 50.6
30, 80, 85, 87
Yes
(80 + 85+ 87)/3.0 = 84.0
75, 85, 10, 60, 90
Yes
(75 + 85+ 60 + 90)/4.0 = 77.5
Consider the following incomplete StudentRecord class. Each studentRecord object stores a list of that
student's scores and contains methods to compute that student's final average.
public class StudentRecord
private int [] scores; // contains scores.length values
// scores.length > 1
// constructors and other data fields not shown
// returns the average (arithmetic mean)
private double average (int [] scores)
{ /* implementation not shown */}
// returns true if the student has completed a make-up
private boolean makeUpCompleted ()
{ /* implementation not shown */ }
// if the student has completed the make-up, return the
// average of all numbers except the lowest one;
// otherwise, return the average of all numbers
public double finalAverage ()
// your code goes here
Write the studentRecord method finalAyerage (), You MUST call the methods average () and
makeUpCompleted () in the finalAverage () method.

Add an equals(Object o) method that will compare unique instance variable data and return true if two of your snowflakes are the same. Your equals method should override the method from the Object class and call the equals method of AbstractShape Your snowflake should be a different color and move in a different and unique way.
canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state.

Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…
