What is Inheritance?
Byte Streams inherit from InputStream and OutputStream

Reads bytes from a file
FileOutputStream
Writes bytes to a file
DataInputStream
Allows for reading primitive data types from an underlying input stream
DataOutputStream
Allows for writing primitive data types to an underlying output stream

What is String formatting
It allows you to create strings that include dynamic content such as variables or expressions
