public static boolean restore(String filePath){
    boolean status = false;
    String username = "name";
    String password = "pword";
    String[] command = new String[]{"mysql", "database_name", "-u" + username, "-p" + password, "-e", " source "+filePath };

    try {

}

//for testing
public static void main(String args[]){
    String backupName = "D:/DatabaseBackup/backupHvs.sql";
    DatabaseManager.restore(backupName);
}
