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

Given the starter code and instructions for 3 methods.

How can I implement those 3 methods into the code?

public abstract class Ride {
protected final String name;
protected double profits;
protected int lastInspection;
protected String[] passengers;
public Ride (String id, int runsSince Inspection, String[] passengers) {
this.name = name;
this.profits
0;
}
=
}
this.lastInspection = 0;
this.passengers = new String[passengers.length];
for (int i = 0; i < passengers.length; i++) {
this.passengers[i] = passengers [i];
}
public Ride (String name, String[] passengers) {
this (name, 0, passengers);
public abstract boolean ableToRun(int numberofRuns);
public abstract boolean checkRide (String[] components);
public abstract double costPerPassenger (int numberOfStops);
public abstract boolean addPassengers(int numberOfStops, String[] newPassengers);

f) chargePassenger
i)

iii)
g) removePassenger
i)
ii)
iii)
iv)
v)
h) Equals
i)
Takes in an int number of stops and increases earnings accordingly.
This method does not return anything.
This method should not be allowed to be overridden.
ii)
iii)
iv)
Takes in a String representing the name of a passenger.
If the name is not in the passenger array, return false.
If the name is in the passenger array, remove the passenger by setting that index to null and return
true.
This method should only remove the first occurrence of the named passenger, case-insensitive.
Assume that the input name is not null.
Overrides the equals method from Object.
Two Ride objects are equal if they have equal name and lastInspection.
Your implementation of the equals method must be symmetric.
I.e., for two non-null objects a and b, a.equals(b) == b.equals(a) must always be true.
