Question

Use java.  Random rand = new Random(), for loop, for nested loop 
Run 5 simulations of 10 districts 

The requirements is on the image 1

See image2 for the expected output.
For the results: suppose that left represents our candidate, and right represent the opponent candidates. The number is equals to the total vote received in 10 districts 

Simulating the Election
Your program will run a series of simulations of the same election. Each simulation will be run as follows:
1. For each district:
1. Randomly determine how many people voted in this district.
2. Randomly determine what percentage of the vote our candidate received in this district.
3. Multiply these two values together to compute how many votes our candidate received in this district.
4. Add the number of votes our candidate received and the total number of votes cast in this district to
the overall totals.
2. Compute the overall percentage of the vote our candidate received across all districts.
3. Print out the results (see below)
4. Add the turnout and votes earned in this simulation to the overall totals (see below)
Your program should execute this entire procedure (including the output) for each simulation. After all simulations
have been run, your program should all print out the average vote percentage our candidate received across all
simulations. (If we've done things right, that should be pretty close to the polling average, though it won't exactly
match.)

Thank you. But can you only use Boolean to printed out whether is true or false? Because we haven't learn the if, else if yet. Further, see the images for more requirements.

Thank you

Our candidate received 2668 votes, so we print 26 + s. Their opponent earned 2452 votes, so we print 24 - s
Notice that we want to align the beginning of each set of symbols-- make sure to account for that in your output.
Computing the Average
The final line of output from your program should be the average vote percentage received by our candidate
across all simulations. Note that we are computing the average percentage, not the overall percentage. That is,
your program should compute the average of the percentage of the vote that our candidate received in each
simulation; it should not compute the total nurfiber of votes received and cast and then divide.

For example, suppose we ran 5 simulations and got the following results:
• Simulation 1: Received 55 out of 100 votes, 55%
• Simulation 2: Received 40 out of 80 votes, 50%
• Simulation 3: Received 30 out of 40 votes, 75%
• Simulation 4: Received 52 out of 100 votes, 52%
• Simulation 5: Received 45 out of 75 votes, 60%
In this case, the average vote percentage is 58.4%, the result of averaging the percentages in each simulation
(55, 50, 75, 52, 60). (This is not the result of dividing the total number of votes received (222) by the total number of
votes cast (395), which would yield 56.2%.)
Constants
To simulate an election, we will need the following values, each of which will be represented by a class constant
in your program:

Visualizing the Vote
While we do not yet have the tools to produce fancy looking graphs, we can still create a simple data visualization
using text! (We'll explore this more in a future assignment.) The way we produce this visualization is quite simple:
• Print one symbol for every 100 votes, rounding down.
• Print a + for votes received by our candidate and a
• Print all +s on one line, followed by all -s on a second line.
As a specific example, consider simulation #3 from the log above, reproduced here:
Running simulation #3:
Win? true
Results: 2668 (52.109375%)
