math - pow (x,y) in Java

Question

What's the difference between:

Math.pow ( x,y ); // x^y

To:

x^y; // x^y

?

Will I prefer to use x^y with double type numbers? Or shell I have to use always with Math.pow() method?

Answer 1

^ is the bitwise exclusive OR (XOR) operator in Java (and many other languages). It is not used for exponentiation. For that, you must use Math.pow.
