spring - the code is running successfully for the backup of mysql file in java

Question

I am trying to get the backup of SQL file using the below status code, returning status code:0, when assumed as cmd it is executed successfully but otherwise there is some error. So the below code is running successfully but the output file is not generating don't know why.

Code: String filePath="/backup/"; String executeCmd = "mysqldump -u " + user + " " + dbname + " -r " + filePath+"backup.sql";

        //String executeCmd = "mysqldump -u " + user + " -p" + password + " " + dbname + " -r " + filePath+" backup.sql";

        Process runtimeProcess = Runtime.getRuntime().exec(executeCmd);
        status = runtimeProcess.waitFor();
        if (status == 0) {
            System.out.println("Backup taken successfully");
        } else {
            System.out.println("Could not take mysql backup");
        }
