Question
In image 1, for the visualize the result with + and -
Can you just use another simple way to do it ? Like use for loop and simple calculation to do it?
because I didnt learn repeat() yet. Thank you
Image two is the expected output.
![The image contains a Java program that simulates voting behavior across districts. Here is a transcription and explanation of the code:
```java
// Import the Java.util.* Library
import java.util.*;
public class Main {
public static void main(String[] args) {
// Create a new Scanner object
Scanner sc = new Scanner(System.in);
Random rn = new Random(); // Create an object of the Random class
// Initialize variables for number of districts and simulations
int districts = 10;
int simulations = 100;
// Initialize variables to calculate total vote percentage and initialize it with 0
double total_vote_percentage = 0;
boolean win;
int simWin = 0;
for (int i = 0; i < simulations; i++) {
win = false;
// Create a double variables turnout_total and votes_total. Initialize them with 0
double turnout_total = 0, votes_total = 0;
System.out.print("Running simulation: (" + (i + 1) + "/" + simulations + ")\n");
// Create a for loop for the number of simulations

// Create a random integer from 1 to 100 and store it in integer variable people
int people = rn.nextInt(100) + 1;
double vote_percentage = rn.nextDouble();
// Calculate and store the number of votes in integer variable

// Accumulate the number of votes earned in the district and store it in double variable votes_earned

}
// Store the boolean value depending on whether the total number of votes our candidate earned in total
simWin += votes_total > (turnout_total / 2) ? 1 : 0;
System.out.println("(" + votes_total + "/" + turnout_total + ")");

- Visualization: `+++++++++++++++++++++++++++++++++++`
- **Average Vote Percentage: 46.276741057787866%**
---
**Explanation of Visualizations:**
For each simulation, a bar graph visualization accompanies the numerical results, using `+` symbols to represent successful votes, and `=` or `-` symbols representing unsuccessful ones, depending on the simulation. The length and symbols of the visualization provide a quick visual insight into the proportion of votes.
**Program Conclusion:**
- The program concludes successfully with an exit code of 0.
This information could be useful for educational purposes by demonstrating how simulations in programming and data visualization can represent statistical outcomes in elections or voting scenarios.
