A square is divided into four smaller regions as shown in (a). If you throw a dart into the square one million times, what is the probability for the dart to fall into an odd-numbered region? Write a program to simulate the process and display the result.
Write a program that reads 11 integers, compares eachinteger with the 11th integer, and displays whether the integers are “greater”,“smaller”, or “equal” to the 11th integer.
THIS IS MEANT TO BE IN JAVA
So far we've learned variables, branches, loops, and some array. The assignment is:
Write a program with total change amount in pennies as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies.
Ex: If the input is:
0
the output is:
No change
Ex: If the input is:
45
the output is:
1 Quarter 2 Dimes
Please show the end result and why you added what you added. This is what I have so far:
import java.util.Scanner;
public class LabProgram {public static void main(String[] args) {}}

In the square extraction method, when the number of digits of the generated random number is n, the square of the initial value s is calculated, and that value is regarded as a 2n digit number (the number of digits squared as shown in the example below). If is not enough, 0 is added.) The n numbers in the center are used as the first random number. Next, square this random number and take the n numbers in the center in the same way to make the next random number.arrow_forward
