infrared sensors as input to parallel port

Hi...We have been working on our final year project and we need a little help regarding certain topics ....

1 . How do we connect infrared sensors to parallel port ... i mean how do we get the input through the parallel port . ( We have knowledge about connecting LEDs to parallel port but we fail on this subject )

2. Can we write a program on Java for the same .

your replies awaited
