How to save data into a file using selenium

public static void main(String[] args) throws IOException {

    System.setProperty("src/driver/chromedriver", "G:\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("https://www.premierleague.com/tables");

    WebElement table;

    table = driver.findElement(By.xpath("//*[@id=\"mainContent\"]/div/div[1]/div[3]/div/div"));
    String dataoutput;
    dataoutput = table.getText();
    System.out.println(dataoutput);

    String csvOutputFile = "table.csv";

    File filedata = new File("src/main/table.csv");
    if (filedata.exists() && !filedata.isFile()) {
        FileWriter writecsv = new FileWriter("src/main/table.csv");
        String datas = dataoutput;
        writecsv.append(dataoutput)
    }
}

This is my code but it isn't saving data to file
