Uses FileInputStream, a subclass of InputStream, to read "example.txt". Reads characters one at a time and prints them. Uses try-with-resources, which automatically calls close () at the end. The following example shows the usage of Java InputStream mark (int readLimit) method.

We will learn about input streams and output streams in detail in the later tutorials. Depending upon the data a stream holds, it can be classified into: Byte stream is used to read and write a single byte (8 bits) of data.
