backup database of mysql code not working

Question

I used following JAVA code for write a backup file of MySQL database, but when I run this code there is no backup created. What is the problem with this ?

public void writeBackup(String date, int x) throws IOException, InterruptedException 
{
    Runtime runTime = Runtime.getRuntime();
    Process runtimeProcess = runTime.exec("mysqldump Healthplus -h localhost -u root -pmysql -r D:/HealthplusBackups/Healthplus" + date + ".sql");
}

Answer 1

The mysqldump command should read

mysqldump -f --opt --user=root --password=mysql --databases Healthplus > D:/HealthplusBackups/Healthplus" + date + ".sql

However it assumes you have access to the folder on the D drive, and it will also do a force dump so if there are any errors it should continue.
