What is Math pow ()?

The Math. pow() function returns the base to the exponent power, as in base^exponent , the base and the exponent are in decimal numeral system. Because pow() is a static method of Math , use it as Math. ( Math has no constructor.) If the base is negative and the exponent is not an integer, the result is NaN.

What does >> and << mean in Java?

A. Google for “Java operators” And the result is this: The signed left shift operator “<<” shifts a bit pattern to the left, and the signed right shift operator “>>” shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand.
