Narrowing Type Conversion: Why is assignment of int to a byte in a declaration allowed?

Question

This may sound too trivial for an intermediate Java programmer. But during my process of reviewing Java fundamentals, found a question:

Why is narrowing conversion l

Answer 1

From here:

Assignment conversion occurs when the value of an expression is assigned (§15.26) to a variable: the type of the expression must be converted to the type of the variable. Assignment contexts allow the use of an identity conversion (§5.1.1), a widening primitive conversion (§5.1.2), or a widening reference conversion (§5.1.4). In addition, a narrowing primitive conversion may be used if all of the following conditions are satisfied:

• The expression is a constant expression of type byte, short, char or int.
• The type of the variable is byte, short, or char.
• The value of the expression (which is known at compile time, because it is a constant expression) is representable in the type of the variable.

In your example all three conditions are satisfied, so the narrowing conversion is allowed.

P.S. I know the source I'm quoting is old, but this aspect of the language hasn't changed since.
