public static double Math.pow(double a, double b); Which is defined in the java.lang package.. so no imports necessary. Raises the first arg to the second, i.e: a^b |

no not that one, its something else...here let me copy the question out, maybe it should make a difference. Create a class called Number***. This class should have an instance variable, called num, that will hold an integer value that will be the basis for all operations using this object. You should have a constructor that initializes num to hold the base value. Your class should include methods that will use various methods from the Math class to do the following: a. A method that will return double the value of the num value. Call this method double(). b. A method that will return square the value of the num value. Call this method square(). c. A method that will return the square root of the num value. Call this method root(). d. A method that will take a parameter and return the quotient of the parameter divided by num rounded up to the nearest integer. Call this method divUp(). e. A method that will return the value of num to the power of a parameter. Call this method power(). i've done all but e |

whats wrong with this.. you using the same method: pow. but ur using it differently (sort of). And the question does not say anything about using a method more than once.

woops i think i read ur question wrong. the methods are instance methods and affect (or work on) an instance variable.. |
