Activity Outcomes:

Student will be able to:

1) Describe the concept of an I/O stream
2) Explain the difference between text files and binary files
3) Save data
4) Read data

In this lab you will experiment with the Java Input/Output components by implementing two programs that read input from a file and write output to a file.

The java.io package contains nearly every class you might ever need to perform input and output (I/O) in Java. All these streams represent an input source and an output destination. The stream in the java.io package supports many data such as primitives, object, localized characters, etc.
