Syntax

ObjectInputStream.readByte() has the following syntax.

public byte readByte()  throws IOException

Example

In the following code shows how to use ObjectInputStream.readByte() method.

//from w w  w  .j  a v a  2s  . c o m

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class Main {

  public static void main(String[] args) throws Exception {

    byte b = 12;

    FileOutputStream out = new FileOutputStream("test.txt");
    ObjectOutputStream oout = new ObjectOutputStream(out);

    // write something in the file
    oout.writeByte(b);
    oout.writeByte(21);
    oout.flush();
    oout.close();
    // create an ObjectInputStream for the file we created before
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream(
        "test.txt"));

    // read and print a byte
    System.out.println((char) ois.readByte());

    // read and print a byte
    System.out.println((char) ois.readByte());
    ois.close();

  }
}

The code above generates the following result.
