Linux Commands that we use Frequently
ls - list all items in a directory
cd - change directory
mkdir - make directory
sudo - enter admin priveleges
code - enter into GUI (vscode)
git clone - clones git repository into own
cat - view a file
import getpass, sys
# method to display question and get user's answers
def question_with_response(prompt, qCount):
print("Question " + str(qCount) + " : " + prompt)

"What does the command 'sudo' do": "enter admin priveleges",
"What does the command 'code' do": "enter into GUI (vscode)",
"What does the command 'git clone' do?": "clones git repository into own computer",
"What does the command 'cat' do": "views a file"
}
# number of questions as length of the dictionary
questions = len(questionsDict)
# set correct to 0
correct = 0
print('Hello, ' + getpass.getuser() + " running " + sys.executable)
print("You will be asked " + str(questions) + " questions.")
print("Are you ready to take a test! Press Enter key to begin. Best of luck :)")

questionCount = 0
# iterate over list of keys from the dictionary. pass dictionary key as question to the question_with_response function
for key in questionsDict:
questionCount += 1
rsp = question_with_response(key, questionCount)
# compare the value from the dictionary to the user's input
if rsp.lower() == questionsDict[key].lower():
print(rsp + " is correct! Good Job!")
correct += 1
else:
print(rsp + " is incorrect! Better Luck next time.")
# print final score

Notes for this Hack:
A basic Review for Linux Commands which is important for basic function around the computer to access the different github repositories that I need to use for the class
Basic Java Concepts
method: In Java, a method is a block of code that performs a specific task or action.
main method: In java, a main method is the entry point when your run the java application.

Java Hello Hacks
// Hack 1: Explain Anatomy of a Class in comments of program (Diagram key parts of the class).
// Hack 2: Comment in code where there is a definition of a Class and an instance of a Class (ie object)
// Hack 3: Comment in code where there are constructors and highlight the signature difference in the signature
//Hack 4: Call an object method with parameter (ie setters).
// Definition of the class
public class Person
{
// body of the class
// Method of Class
public void information(int age, String email, double salary){
System.out.println("User is: " + age + "years old!");
System.out.println(age);
System.out.println(email);
System.out.println(salary);
}
public static void main(String[] args) {
// Instance of the Class
Person shivansh = new Person();
// Calling an object method with parameters
shivansh.information(10, "testing", 20.5);
}
}
Java Hello Hacks Additional Requirements
public class Class1 {

}
public static void main(String[] args){
Person person1 = new Person("Person1", 15);
Dessert dessert1 = new Dessert("Ice Cream", 15);
}
}
import java.util.ArrayList; // import the ArrayList class
// Go through progression of understanding a Static Class. Build a purposeful static Class, no Objects.
// Calculate stats functions on an array of values: mean, median, mode.
ArrayList<Integer> numbers = new ArrayList<Integer>();
numbers.add(1);
numbers.add(2);
numbers.add(2);

import java.util.ArrayList; // import the ArrayList class
import java.util.HashMap; // import Hashmap Class
// Fixed Array
int[] numbers = {1, 2, 3, 4, 5};

ArrayList<String> integers = new ArrayList<String>();
integers.add("1");
integers.add("2");
integers.add("3");
integers.add("4");
System.out.println(integers);
// Different methods using ArrayList
// Changing at item in arraylist
integers.set(0, "1");
// Hashmap
HashMap<String, Integer> people = new HashMap<String, Integer>();

people.put("Person1", 15);
people.put("Person2", 16);

// Getting input from the user

System.out.println("Choose one: rock,paper,scissors");
String playerMove = scanner.nextLine();
// Getting input from the Opponent
Random random = new Random();
int othernumber = random.nextInt(3);
String opponentMove;
// If, else if, else statement:
if (othernumber == 0) {
opponentMove = "rock";
} else if (othernumber == 1) {

Reviewing the 10 Units of Computer Science A and how identifying if we used them
Unit 1: Primitive Types
Unit 2: Using Objects
Unit 3: Boolean Expressions and if Statements
Unit 4: Iteration
Unit 5: Writing Classes
Unit 6: Array
Unit 7: ArrayList
Unit 8: 2D Array
Unit 9: Inheritance
Unit 10: Recursion
I applied Arrays, ArrayLists, Primitive Types, and Using Objects in the code above
Answer why you think this reorganization and AP indetification is important?
Reorgnaizations aad AP identification is important because they show what pices of code you are suppossed to use for your individual projects and requirments. It also shows where you are at in terms of using the various skills in Java and if you are at AP standards
Review of Week 1 Hacks
What did I learn of Week 1 Hacks:
- From the Java Hello Hacks I learned all the different parts of a class and how they function together
- Also From the Java Hello Hacks I learned how to create static methods and calling them from an instance of the class
- From Java Console Hacks I learned about how to use fixed array, Arraylist, and Hashmap. Out of these three, I think that Hashmap definetly is the most interesting to me.
- Also From the Java Console Hacks I became more prficient in the use of Scanners and to gain user input.
- Lastly, I learned about the 10 differnet units for AP Computer Science A and learned if I can maybe apply them in future programming
Week 2 Hacks: HTML Table Hacks
Hacks:
- Make your own tables, with data according to your interests.
- Describe a benefit of a markdown table.
- Try to Style the HTML table using w3schools.
- Describe the difference between HTML and JavaScript.
- Describe a benefit of a table that uses JavaScript.

Describe a benefit of using markdown tables
A benefit of using markdown tables is that it is very easy to show data that would be organized in tables, such as statsitics and other facts that can be shown such as the table above.
Try to Style the HTML table using w3schools.
In W3 schools styles HTML Tables in zebra stripes
Describe the difference between HTML and JavaScript.
The Difference between HTML and Javascript is that HTML gives the basic structure and meaning for web content whereas javascript is more advanced of a programming langauge
Describe a benefit of a table that uses JavaScript.
A beneift of a table that uses JavaScript includes that it is more advanced and can have more features as well as style becuase javascript is a more advanaced programming langauge than HTML.
Review of Week 2 Hacks
- Learned about how to use HTML Tables with Javascript to show information and statsitics
- Learned how to add an entire column to Javascript Query Tables
- Learned how to Style HTML Tables
- Learned the difference between HTML and Javascripot
- Learned about the benefits of using a tables with Javascript that is being used.
