random access reading to large size text files

Hi everybody,

I have been trying to parse a 100MB log file(tab separated). Basic aim is to read the file randomly, do some procesing and then display the contents of the file line by line. Working with randon access file class makes reading very slow.
Is there any alternative to random access files class in java whereby faster file processing is possible??
