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)
ii)
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.

THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline. But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far... import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new…
Still referencing Java, (I hope this is how follow-up questions work, you know my previous question) how could method overloading help reduce errors and are method overloads a top-down or bottom-up approach? Or, is there a difference between top-down and bottom-up in consideration to overloading methods vs writing the actual program?
Answer the given question with a proper explanation and step-by-step solution. USING JAVA: ---Sorting the Invoices via dates--- Another error that will still be showing is that there is not Comparable/compareTo() method setup on the Invoice class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the Invoice class. The compareTo() method will take a little work here. We are going to compare via the date of the invoice. The dates of the Invoice class are by default saved in a MM-DD-YYYY format. So they have a dash '-' between each part of the date. So you will need to split the date of the current invoice AND split the date of the object sent to the method. We have three things to compare against here. First we need to check the year. If the years are the same then you should go another step forward and compare the months. If the months are the same then you will lastly have to compare the day. Use whatever…

Can you implement an interface in your class? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Problem Statement# You are given an interface Addition which contains a method signature int add(int num1, int num2). You need to write a class called Calculator which implements the Addition interface. The add(int, int) method takes two integers and returns their sum. Input# Calls the add(int, int) method by passing num1 and num2. Output# Returns the addition of num1 and num2.
TASK 8. Repeat TASKs 4-7. Change Summation Integers problem to Finding the minimumproblem. Make sure you properly wrote/updated all text messages, method names,and math calculations.Hint: You can use java.lang.Math.min() method.Example: System.out.printf("The min of the integers %4d and %4d and %4dis %7d\n", a, b, c, MinTest(a, b, c));Submit the source code files (.java files) and the console output screenshots
Write a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.
