Byte b2 = new Byte(b);
System.out.println(b1 == b2);
System.out.println(b1.equals(b2));
}
}

Try compiling it yourself. What error does the compiler give you exactly? Read the error message carefully and try to understand what it means.

Byte b1= new Byte(100);
literals like 100 are of integer type by default.

To create a Byte object using new you should pass a byte

Try this
Byte b1= new Byte((byte)(100));
