Programs need a way to receive input. An InputStream is a class that provides several overloaded methods for reading input. System.in is the system’s standard input, typically your keyboard. System.in is a byte stream, meaning it’s read() method reads the first 8-bit ASCII value from the buffer.
An exception is an event that disrupts a program’s execution. When using an InputStream, you will need to deal with exceptions by appending throws IOException at the end of the main() method header. The throws clause tells the JVM that the method may throw an exception.
