Java.io.FilterInputStream.read()Method
Description
The java.io.FilterInputStream.read() method reads the next byte of the data from the input stream. The value byte returned is in the range 0 to 255. The method returns -1 if the end of the file is reached.
Declaration
Following is the declaration for java.io.FilterInputStream.read() method −
public int read()
Parameters
NA
Return Value
The method returns the next byte of data, or -1 if the end of the stream is reached.
Exception
IOException − If an I/O error occurs
Example
The following example shows the usage of java.io.FilterInputStream.read() method.
package com.tutorialspoint; import java.io.BufferedInputStream; import java.io.FileInputStream; import java.io.FilterInputStream; import java.io.IOException; import java.io.InputStream; public class FilterInputStreamDemo { public static void main(String[] args) throws Exception { InputStream is = null; FilterInputStream fis = null; int i = 0; char c; try { // create input streams is = new FileInputStream("C://test.txt"); fis = new BufferedInputStream(is); // read till the end of the stream while((i = fis.read())!=-1) { // converts integer to character c = (char)i; // prints System.out.println("Character read: "+c); } } catch(IOException e) { // if any I/O error occurs e.printStackTrace(); } finally { // releases any system resources associated with the stream if(is!=null) is.close(); if(fis!=null) fis.close(); } } }
Assuming we have a text file c:/test.txt, which has the following content. This file will be used as an input for our example program −
ABCDEF
Let us compile and run the above program, this will produce the following result −
Character read: A Character read: B Character read: C Character read: D Character read: E Character read: F
