Example
The following example shows the usage of java.io.PushbackInputStream.reset() method.
package com.tutorialspoint; import java.io.*; public class PushbackInputStreamDemo { public static void main(String[] args) { // declare a buffer and initialize its size: byte[] arrByte = new byte[1024]; // create an array for our message byte[] byteArray = new byte[]{'H', 'e', 'l', 'l', 'o'}; // create object of PushbackInputStream class for specified stream InputStream is = new ByteArrayInputStream(byteArray); PushbackInputStream pis = new PushbackInputStream(is); try { // read from the buffer one character at a time for (int i = 0; i < byteArray.length; i++) { // read a char into our array arrByte[i] = (byte) pis.read(); // display the read byte System.out.print((char) arrByte[i]); } // try to call the reset method, but it is not supported pis.reset(); } catch (Exception ex) { ex.printStackTrace(); } } }
Let us compile and run the above program, this will produce the following result −
