Create a game that rolls two dies (number from 1 to 6 on the side) sequentially for 10 times (use loop). If at least once out of 10 times the sum of two random numbers is equal to 10, you win, else you loose. You will need to get your own method getRandom(int n) that generates a random number, see below (you can modify it as needed), a loop, and IF statement in the loop that checks if a sum of two random numbers is 10 or not.
Please start your program as follows, similar to what we did in class:
import java.util.Random;
public class UseRandom{
//your method getRandom() is here below, n is a range for a random number from 0 to n
public int getRandom(int n)
{
Random r=new Random();
int rand=r.nextInt(n);
return rand;
}
//code continues here, don't forget your main() method inside the class, and making your own object in main() using "new" keyword.
Answer:
Explanation:
The following code is written in Java and loops through 10 times. Each time generating 2 random dice rolls. If the sum is 10 it breaks the loop and outputs a "You Win" statement. Otherwise, it outputs "You Lose"
import java.util.Random;
class Brainly {
public static void main(String[] args) {
UseRandom useRandom = new UseRandom();
boolean youWin = false;
for (int x = 0; x<10; x++) {
int num1 = useRandom.getRandom(6);
int num2 = useRandom.getRandom(6);
if ((num1 + num2) == 10) {
System.out.println("Number 1: " + num1);
System.out.println("Number 2: " + num2);
System.out.println("You Win");
youWin = true;
break;
}
}
if (youWin == false) {
System.out.println("You Lose");
}
}
}
class UseRandom{
public int getRandom(int n)
{
Random r=new Random();
int rand=r.nextInt(n);
return rand;

Suppose that a minus sign in the input indicates pop the stack and write the return value to standard output, and any other string indicates push the string onto the stack. Further suppose that following input is processed:
this parrot - wouldn't voom - if i put -- four thousand --- volts - through it -
What are the contents (top to bottom) left on the stack?
a. through wouldn't this.
b. this wouldn't through.
c. it through wouldn't.
d. it through volta.
e. volts through it.
Answer:
e. volts through it
Explanation:
volts through it
The contents (top to bottom) left on the stack is volts through it. Thus, option E is correct.
What is standard output?When a computer program begins execution, standard streams are interconnected input and output channels of communication between the program and its surroundings. The three I/O connections are known as standard input (stdin), standard output (stdout), and standard error (stderr).
A negative sign in the input indicates that the stack should be popped, and the return value should be sent to standard output, whereas any other string means that the string should be pushed into the stack. Assume that the following input is processed: this parrot would not voom if I pushed — four thousand —- volts - through it.
The contents of the stack (from top to bottom) are volts via it. As a result, option E is correct.

Write a program that prompts the user to enter a series of numbers between 0 and 10 asintegers. The user will enter all numbers on a single line, and scores will be separatedby spaces. You cannot assume the user will supply valid integers, nor can you assumethat they will enter positive numbers, so make sure that you validate your data. You donot need to re-prompt the user once they have entered a single line of data. Once youhave collected this data you should compute the following: • The largest value • Thesmallest value • The range of values • The mode (the value that occurs the most often) •A histogram that visualizes the frequency of each number Here’s a sample running of theprogram.

Requirements description:
Assume you work part-time at a Cafe. As the only employee who knows java programming, you help to write an ordering application for the store.
The following is a brief requirement description with some sample output.
1. Selecting Breakfast or Lunch(5 points)
When the program starts, it first shows option Breakfast or Lunch. A sample output is as follows.
=== Select Breakfast or Lunch: ===
1. Breakfast
2. Lunch
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 2, the user will see an error message.
A sample output for invalid number is as follows.
Select Breakfast or Lunch [1, 2]: 0
Error! Number must be greater than 0.
Select Breakfast or Lunch [1, 2]:
2. Selecting Coffee (20 points)
When the program continues, it shows a list/menu of coffee and their prices, then asks a user to select a coffee by entering an integer number. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select a coffee [1, 5]:
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 5, the user will see an error message.
A sample output for invalid number is as follows.
Select a coffee [1, 5]: 0
Error! Number must be greater than 0.
Select a coffee [1, 5]:
In your program, you can hard-code the information for coffee (i.e., coffee names and prices) shown above, such as "1 Espresso $3.50" and use the hard-code price, such as 3.50, for calculation of a total price of the order.
After the user makes a choice for coffe, such as 2 for Latte. The program continues asking for selecting a coffee so that the user can have multiple coffee orders. The user can enter "5" to quit coffee selection. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 2
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 5
3. Selecting Food (10 points)
After Coffee selection, the program shows food selection. A sample output is as follows.
=== Select Food: ===
1 Tuna Sandwich $10.00
2 Chicken Sandwich $10.00
3 Burrito $12.00
4 Yogurt Bowl $8.00
5 Avocado Toast $8.00
6 Quit Food selection
Select Food: [1, 6]: 1
Input validation is needed and works as before. Like Coffee selection which allows selecting multiple Coffee orders, food selection also repeats after the user enters a valid number between 1 and 5.
You hard-code the information for food shown above, such as "1 Tuna Sandwich $10.00" and use the hard-code price, such as 10.00, for calculation of the total price of the order.

Complete the Rectangle class. It has a rectangle's length and width as class variables and contains methods to compute its area and perimeter. If either parameter is negative, the method should calculate based on its absolute value. Then, you'll take user inputs to create an instance of Rectangle. For example, if you provide the input -13 7 You should receive the output Perimeter = 40.0 Area = 91.0 Note: It is NOT necessary to use the math module to calculate absolute value, though you may if you want. 298800.1775650.qx3zqy7 LAB ACTIVITY 28.4.1: Final Exam 2021 - Problem 4 of 6 0/10 main.py Load default template... 1 class Rectangle: _init__(self, length, width): # your code here 4 5 def area (self): 6 # your code here 7 8 def perimeter (self): 9 # your code here 10 11 if _name__ == '__main__': 12 1 = float(input) 13 w = float(input) 14 r = Rectangle(1, w) 15 print("Perimeter =', r.perimeter()) 16 print('Area =', r.area(), end='')|
Answer:
The complete program is as follows:
class Rectangle:
def __init__(self, length, width):
self.width = abs(width)
self.length = abs(length)
def area(self):
area = self.length * self.width
return area
def perimeter (self):
perimeter = 2 * (self.length + self.width)
return perimeter
if __name__ == '__main__':
l = float(input(": "))
w = float(input(": "))
r = Rectangle(l, w)
print('Perimeter =', r.perimeter())
print('Area =', r.area(), end='')
Explanation:
This defines the class:
class Rectangle:
This gets the parameters from maiin
def __init__(self, length, width):
This sets the width
self.width = abs(width)
This sets the length
self.length = abs(length)
The area function begins here
def area(self):
Calculate the area
area = self.length * self.width
Return the calculated area back to main
return area
The perimeter function begins here
def perimeter (self):
Calculate the perimeter
perimeter = 2 * (self.length + self.width)
Return the calculated perimeter back to main
return perimeter
The main begins here
if __name__ == '__main__':
This gets input for length
l = float(input(": "))
This gets input for width
w = float(input(": "))
This passes the inputs to the class
r = Rectangle(l, w)
This prints the returned value for perimeter
print('Perimeter =', r.perimeter())
This prints the returned value for area
print('Area =', r.area(), end='')

The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.
