4.6. Summary

The Java input and output package (java.io) provides developers with a comprehensive range of options for reading and writing bytes of data, as well as characters. Once mastered, streams play an important part in application development, and particularly so in the case of network programming. By applying filter streams, or filter readers and writers, to low-level streams, developers can read numbers, arrays, characters, strings, and other datatypes from a sequence of bytes, or write such datatypes to a new sequence of bytes.
