A. A byte variable containing the value 0 or the value 1
B. 11 < 5
C. The literal true
D. myString.equals(myOtherString), where myString and myOtherString are initialized variables of type String

Answer 1

Hm....



















***Boolean expr: just only true or false condition.



A. a byte containing value from 0 ... 255 (unsigned), but a bit containing value 0 or 1.

B. 11 < 5, result false.

C. true, result true.

D. myString equals myOtherString, result true or false.



A not a boolean expr.

Answer 2

Since this question is for the Java programming, the only answer that is applicable is:



A. A byte variable containing the value 0 or the value 1

Answer 3

d.



b is a valid boolean expression. Right 11 is not less than 5, which would return a false value.

Answer 4

I'd say B





11 is not less than 5
