Q. Write a program to read the data from the file using FileInputStream.
Answer:
FileInputStream class is used to read the data from the file. it should be used to read byte-oriented data for example read image, audio, video.
In this example, we read the data from a text file "test.txt" and print the ASCII value of each character. The printStackTrace() method is used to print error message.
//test.txt
Welcome
Output:

int i;
System.out.println("ASCII value of the character:");
while((i=fis.read()) != -1)
{
System.out.print(i+" : ");
System.out.println((char)i);
}
}
catch (FileNotFoundException fnfe)
{
fnfe.printStackTrace();
}
catch (IOException io)
{
io.printStackTrace();
}
}
}
