Answer:
Following are the code to this question:
//import package
import java.util.*;
public class Full_XmasTree //defining class
{
// defining main method
public static void main(String as[])
{
int X,a,b; //defining integer variable
Scanner obx = new Scanner(System.in); // creating Scanner class object
System.out.print("Please enter: "); //print message
X = obx.nextInt(); // input value from user
for (a = 0; a < X; a++) //defining loop to print pattern
{
for (b = X - a; b > 1; b--)//use loop for print white space
{
System.out.print(" ");//print space
}
for (b = 0; b <= a; b++) // use loop to print values
{
System.out.print("* "); //print asterisk values
}
System.out.println(); //using print method for new line
}
}
}
Output:

Explanation:
In the given java code, a class "Full_XmasTree" is declared, in which the main method is declared, inside this method three integer variable "X, a, and b", in this variables "a and b" is used in a loop, and variable X is used for user input.
- In the next line, the Scanner class object is created, which takes input in variable X, and for loop is used to print asterisk triangle.
- In the first for loop, use variable a to count from user input value, inside the loop, two for loop is used, in which first is used to print white space and second is used for the print pattern.
The program is an illustration of conditional statements.
Conditional statements are used to execute instructions, if and only if certain <em>condition or conditions </em>are met.
Take for instance: <em>If b = 5, print "ab"</em>
The above print statement will only be executed, if the <em>value of b is 5</em>
The paper-rock-scissor program in Python where comments are used to explain each line is as follows,
#This imports the random module
import random
#This is used to control the repetition of the game
playagain ="T"
#The following is repeated until the user chooses not to play again
while(playagain == "T"):
#This generates a random choice for the computer
computer = random.choice(['Rock', 'Paper', 'Scissors'])
#This gets input for the player
player = input('Choose: ')
#If the player and computer choose the selection
if player == computer:
#Then, it's a tie
print('A tie - Both players chose '+player)
#If the player wins
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
#This prints "player won" and the reason
print('Player won! '+player +' beats '+computer)
#If otherwise,
else:
#This prints "computer won" and the reason
print('Computer won! '+computer+' beats '+player)
#This asks if the player wants to play again
playagain = input("Play again? T/F: ")
At the end of each round,
- The program displays the winner
- Or prints a tie, if there's a tie
