1)code one:
public static void main(String []args)
{
final int i = 100;
byte b = i;
System.out.println(b);
}

2)Code two:
public static void main(String []args)
{
int i = 100;
byte b = i;
System.out.println(b);
}

Check out the Java Language Specification for a formal definition:final (�4.5.4)
Basically, a variable declared final is a constant -- its value cannot be changed once assigned.
