b. int twoPi = 3.14159; /* holds the value of two times pi */ Valid? Why?

d. double twoPi = 2*3.14159; /* // holds the value of two time pi */ [comment] // Valid? Why?
Only the final sentence is true: double twoPi = 2*3.14159;
What is Java?Due to the fact that twoPi is storing pi at 3.14159 after being multiplied by 2. Therefore, the comment is true.
The first sentence's remark is incorrect since the program will fail to compile unless the value is entered as int twoPi = (int)(2*3.14159);
the second statement is also incorrect because pi is never multiplied by 2, hence it is impossible to save pi times its original value.
The final sentence is similarly incorrect since using an int datatype variable to store that value of pi times two would result in a compile-time error.
