Creating a folder in internal memory

I cannot get methods for creating a folder in internal memory,

I went through several conversations in Android, creating folders in the internal memory and the Problem that occurs when reading a file from the android internal memory . But still I can’t fulfill my requirements.

My requirement: I want to create a folder in the internal memory, there I want to save one video.

Thank you in advance for your valuable feedback.

try below

File mydir = context.getDir("users", Context.MODE_PRIVATE); //Creating an internal dir;
if (!mydir.exists())
{
     mydir.mkdirs();
}

Here is the code that I use to create files in internal memory:

    File myDir = context.getFilesDir();
    // Documents Path
    String documents = "documents/data";
    File documentsFolder = new File(myDir, documents);
    documentsFolder.mkdirs(); // this line creates data folder at documents directory

    String publicC = "documents/public/api." + server;
    File publicFolder = new File(myDir, publicC);
    publicFolder.mkdirs(); // and this line creates public/api.myservername folder in internal memory
