I can't give a working Java code, but in C# it looks like this (below). However, it won't create a file, the result is a folder. It is a totally empty GDB.
[MethodImpl(MethodImplOptions.AggressiveInlining)]
private static Geodatabase CreateFileGDB(string GDBPath)
{
// Test the argument:
const string NameOfGDBPath = nameof(GDBPath);
if (string.IsNullOrWhiteSpace(GDBPath))
throw new ArgumentNullException(NameOfGDBPath, "Geodatabase path cannot be null; empty or whitespace-only string.");
DirectoryInfo directoryInfo = new DirectoryInfo(GDBPath);
if (!directoryInfo.Parent.Exists)
throw new DirectoryNotFoundException("The parent directory (" + directoryInfo.Parent.FullName + ") was not found!");
if (directoryInfo.Exists)
directoryInfo.Delete(true);
//Create the GDB:
return Geodatabase.Create(directoryInfo.FullName);
}
