So I have this question for a Java class I am taking. It is very simple and maybe I am just missing something simple but I can’t seem to figure out how to do this:
Code and test a boolean expression that returns true if an integer variable “n” is in the range -15 to 50 inclusive but not odd in the range 10 to 20 inclusive.
The method I have been trying is this:
System.out.println(n%2==0 && n > 10 && n < 20 && n>-15 && n < 50);
While it does the non-odd number and 10-20 inclusivity correctly it will not state that a value is "true" when outside of the 10-20 range.
p.s question requires this to be done in a sout line
Using parentheses helps to better represent your condition, which I’ve reproduced here, annotated on what I believe to be the correct solution.
System.out.println( // true if an integer variable “n” is n >= -15 && n <= 50 // in the range -15 to 50 inclusive && !( // but not n % 2 == 1 // odd && n >= 10 && n <= 20 // in the range 10 to 20 inclusive. ) );
note that I use
<=, rather than
<, because it says "inclusive".
I don’t think it’s possible to represent this expression in a single line without using some parentheses to group some of the checks together.
