Unit 6: Lesson 2 - Coding Activity 1 AP Computer science

Answers

Answer 1

The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise

The method in java, where comments are used to explain each line is as follows:

//This defines the method

public static boolean chkNegative (double[] myArr) {

   //This initializes a boolean variable

   boolean isNeg = true;

   //This iterates through the array

   for (int i = 0; i < myArr.length; i++) {

     //If the array element is 0 or positive

     if (myArr[i] >= 0) {

         //Then the boolean variable is set to false

       isNeg = false;

       //And the loop is exited

       break;

     }

   }

   //This returns true or false

   return isNeg;

 }

The program is an example of recursion

In computer programming, recursion is a process in which a function calls itself.

In a recursive program, there is a

base case and a recursive case.

When the condition of recursion is met, the base case is returned, else, the recursive case is continued.

In the function given above,

the base case is 'return x' under the condition 'if x == 1'. The recursive case is 'return x * factorial(x - 1)'.

So, the function runs until the base case it met and then it stops.

So, the program is an example of recursion.

A one-point perspective drawing means that the drawing has a single vanishing point, usually (though not necessarily) directly opposite the viewer's eye and usually (though not necessarily) on the horizon line. All lines parallel with the viewer's line of sight recede to the horizon towards this vanishing point.

One Point Perspective is a type of linear perspective that uses a single vanishing point to create the illusion of depth in a work of art.
Parallel – Parallel lines are lines that never touch… even if they are extended indefinitely.
Horizontal Lines – Lines drawn from side to side level with the horizon.

Write a program Election that computes the tally in a write-in election, and announces the winner. Since the votes are write-in, there is no pre-determined set of candidates. Whoever appears the most in the votes is the winner. The user enters the individual votes, one vote per line, and ends entering with typing -1 or an empty line. To compute the tally, the program uses two arrays, a String [ ] variable (names), and an int [ ] variable (count). Upon receiving a single vote, the program checks if the name on the vote appears in names, and if it does, the program adds 1 to the value of the element in count. If the name does not appear in names, the program extends both arrays by one element, stores the name in names at the last position and store 1 in count at the last position. In this manner, the two arrays will have the same lengths. The initial length is 0 for both arrays. Below is an example of how the program may runplease I need to demonstrate the code,I need some comments next to every single line

Answers

The election program illustrates the use of ArrayLists, loops and conditional statements.

ArrayLists are resizable arrays, while loops and conditional statements are used to perform repetitions and make decisions, respectively.

The election program written in Java, where comments are used to explain each line is as follows:

import java.util.*;

public class Main {

 public static void main(String[] args) {

     //This creates a Scanner object

   Scanner input = new Scanner(System.in);

   //This creates a string ArrayList for the names of the candidates

   ArrayList<String> names = new ArrayList<String>();

   //This creates an Integer ArrayList for the vote count of the candidates

   ArrayList<Integer> votes = new ArrayList<Integer>();

   //This declares name as string

   String name;

   //This gets input for the name of the candidates

   name = input.nextLine();

   //This is repeated until the user enters "-1"

   while (!"-1".equals(name)){

       //If name is in the list,

       if(names.contains(name)){

             //This gets the index of the name  

             int pos =names.indexOf(name);

             //This calculates the number of votes

             Integer value = votes.get(pos)+1;  

             //This adds the vote to the vote ArrayList

             votes.set(pos, value);

       }

       //If otherwise

       else{

           //This adds the candidate name to the name ArrayList

           names.add(name);

           //This adds 1 as the vote of the candidate to the vote ArrayList

           votes.add(1);

       }

       //This gets input for the name of another candidates

       name = input.nextLine();

   }

   //This prints the name of the election winner

   System.out.println("Winner : " +names.get(votes.indexOf(Collections.max(votes))));
