does equality operator return a boolean value
even = number % 2开发者_如何转开发 == 0;
This is a valid java assignment which was given in a website as example.
So does equality operator return a boolean value after evaluation ?
Like in this case, number % 2 == 0 , if true, it assigns even = true?
Yes. Comparison operators evaluate to boolean
values.
Yes. From the Java Language Specification, section 15.21:
The equality operators are syntactically left-associative (they group left-to-right), but this fact is essentially never useful; for example, a==b==c parses as (a==b)==c. The result type of
a==b
is alwaysboolean
, and c must therefore be of type boolean or a compile-time error occurs. Thus, a==b==c does not test to see whether a, b, and c are all equal.
(Emphasis mine - the rest of the paragraph is somewhat irrelevant, but it's the context in which the important phrase appears.)
Yes, comparisons made with boolean operators evaluate to a boolean
value
