Question

Create a new class called Calculator with the following methods: 1. A static method called powerlateint numi, int num2) This method should retum pumbl to the power num2. 2. A static method called powerRouble(double numoi, int num2). This method should retum pumpl to the power num2. 3. Invoke both the methods and test the functionalities. Hint: Use Matb.pow(double, double) to calculate the power.

Answer 1

To create a Calculator class with powerInt and powerDouble methods, you can define them using Java's Math.pow function. Then, instantiate the Calculator class and use these methods to calculate powers of integers and doubles, respectively.

Step-by-step explanation:

To create a new class called Calculator with the described methods, you can use the following code snippet:

public class Calculator {
// Static method to calculate integer power
public static int powerInt(int num1, int num2) {
return (int) Math.pow(num1, num2);
}

// Static method to calculate double power
public static double powerDouble(double num1, int num2) {
return Math.pow(num1, num2);
}
}

To test the functionality of both methods:

public class TestCalculator {
public static void main(String[] args) {
// Testing powerInt method
int resultInt = Calculator.powerInt(3, 4); // Should return 81

// Testing powerDouble method
double resultDouble = Calculator.powerDouble(5.69, 4); // Should return a double value

// Output the results
System.out.println("powerInt result: " + resultInt);
System.out.println("powerDouble result: " + resultDouble);
}
}

Using Math.pow is an efficient way to calculate powers in Java. It handles both integral and fractional exponents as well as scientific notation. Remember to experiment with your calculator to understand these operations better.
