What is the correct way to cast an integer to a double?

What is the value of _a_ in _double a = 3 + 2;_?

Consider the following method: public void calculatePower(double base, int exponent) { double result = Math.pow(base, exponent); printPower(base, exponent, result); } public void printPower(double base, int exponent, double result) { System.out.print(base + "^" + exponent + " = " + result); } Assume that the method calculatePower(2, 3) appears in a method in the same class. What is printed as a result of the method call?

Consider the following method: public void calculateSquareRoot(double n) { double squareRoot = Math.sqrt(n); printSquareRoot(n, squareRoot); } public void printSquareRoot(double n, double squareRoot) { System.out.print("Square root of " + n + " = " + squareRoot); } Assume that the method calculateSquareRoot(16) appears in a method in the same class. What is printed as a result of the method call?

What is the result of the following code? public class Shapes { public double calculateCircleArea(double radius) { return Math.PI * Math.pow(radius, 2); } public double calculateRectangleArea(double length, double width) { return length * width; } public static void main(String[] args) { Shapes shapes = new Shapes(); System.out.println(shapes.calculateCircleArea(5) + shapes.calculateRectangleArea(10, 2)); } }

Consider the following class definition. public class Animal { private String species; private int age; private double weight; public Animal(String animalSpecies, int animalAge, double animalWeight) { species = animalSpecies; age = animalAge; weight = animalWeight; } public void eat() { weight += 5; } public double getWeight() { return weight; } } Assume that the following code segment appears in a class other than Animal. java Copy code Animal dog = new Animal("Dog", 3, 15); dog.eat(); System.out.println(dog.getWeight()); What is printed as a result of executing the code segment?

What is the result of the following code?<br>Double d = 3.14;<br>System.out.println(d);

Which of the following is a correct way to convert a double to a Double object?
