Welcome to JavaRanch.
That's quite easy to find out, isn't it?

The First Snippet will compile, run and print 100.
The second Snippet will not compile.
In the First Snippet, i is cmpile time constant and its value 100 is in the range of byte so no explicit casting is required.
In the Second Snippet, i is not compile time constant. So, you have to explicitly cast the value of integer i to byte.
byte b = (byte)i will work.
