Byte b=new Byte(1); //<-here

The constructor for a Byte does not take an integer value but a String value instead. See below.

Byte b = new Byte("1");

Actually there are two constructors:

(Toggle Plain Text)

1.  Byte(byte value) 
2.  Byte(String s)

Example of each:

(Toggle Plain Text)

public class ByteTest {
    public static void main(String[] args) {
	byte aByte = 1;
        Byte byte1 = new Byte( aByte );
        System.out.println( byte1 );

	String strByte = "1";
        Byte byte2 = new Byte( strByte);
        System.out.println( byte2 );
    }
}

So to answer your question, you could create a Byte from an integer with a simple cast like so:

(Toggle Plain Text)

Byte b = new Byte( (byte)1 ) );
