Returns

The 8-bit byte read.

Throws

IOException

Example 1

  import java.io.*;    public class ObjectInputStreamreadunsignedByteExample1 {     public static void main(String[] args) {      short b = 32767;        try {           FileOutputStream outstream = new FileOutputStream(“file1.txt”);           ObjectOutputStream objoutstream = new ObjectOutputStream(outstream);           objoutstream.writeByte(b);           objoutstream.flush();           ObjectInputStream objinstream = new ObjectInputStream(new FileInputStream(“file1.txt”));             // read and print the  using  readUnsignedByte           System.out.println(” byte value: ” + objinstream.readUnsignedByte());                     } catch (Exception ex) {           ex.printStackTrace();        }     }  }  

Output:

byte value: 255

Example 2

  import java.io.*;       public class ObjectInputStreamreadunsignedByteExample2    {       public static void main(String[] args) throws IOException       {           FileOutputStream outstream = new FileOutputStream(“file1.txt”);           ObjectOutputStream objoutStream = new ObjectOutputStream(outstream);           ObjectInputStream objinStream  = new ObjectInputStream(new FileInputStream(“file1.txt”));               objoutStream.writeByte(121212);               objoutStream.flush();           System.out.println(“readUnsignedShort() : ” + objinStream.readUnsignedByte());       }   }  

Output:

readUnsignedShort() : 124
