How can I get back the number of my card SIM in JAVA?

I found the function with C# but I didn't understund it?

there is somebody who can help me?

the function in c#:
string num()
{
Tapi tapi = new Tapi();
tapi.Initialize();

Hashtable DeviceCaps;
int deviceIDCell = -1;
DeviceCaps = new Hashtable();
string szPhoneNumber = "";

for( int i = 0; i < tapi.NumDevices; i++ )
{
LINEDEVCAPS dc = new LINEDEVCAPS(1024);
dc.Store();
int dwVersion = tapi.NegotiateVersion(i);
int ret = NativeTapi.lineGetDevCaps(tapi.hLineApp, i, dwVersion, 0, dc.Data);
if ( ret < 0 )
continue;
if ( (LINEERR)ret == LINEERR.STRUCTURETOOSMALL )
{
dc.Data = new byte[dc.dwNeededSize];
ret = NativeTapi.lineGetDevCaps(tapi.hLineApp, i, dwVersion, 0, dc.Data);
}
dc.Load();

if (dc != null && dc.ProviderName == CellTSP.CELLTSP_PROVIDERINFO_STRING)
{
LINEADDRESSCAPS ac = new LINEADDRESSCAPS(1024);
ac.Store();
ret = NativeTapi.lineGetAddressCaps(tapi.hLineApp, i, 0, dwVersion, 0, ac.Data);
ac.Load();
szPhoneNumber = Encoding.Unicode.GetString(ac.Data, ac.dwAddressOffset, ac.dwAddressSize);

ac = null;
deviceIDCell = i;
break;
}

}

if (deviceIDCell == -1) // Not found
MessageBox.Show("Could not find cellular line");

tapi.Shutdown();
return szPhoneNumber;
}
