Replacement of std.stream

[DlangLearner via Digitalmars-d-learn]

I will convert a Java program into D. The original Java code is 
based on the class RandomeAccessFile which essentially defines a 
set of methods for read/write Int/Long/Float/String etc. The 
module std.stream seems to be a good fit for this job, but in its 
documentation, it is marked deprecated. So I'd like to know what 
is the replacement for this module. If I don't use this module, 
what is the other apporach I should use. Thanks for help.
