Chapter 13: Problem 46

Write a statement that defines an array of five objects of the Circle class in question

Short Answer

Expert verified

**Answer:** To create an array named "circles" that holds five Circle objects in Java, first declare the array using `Circle[] circles;`, then initialize it with a size of five using `circles = new Circle[5];`. Finally, use a for loop to instantiate each object in the array: ```java Circle[] circles = new Circle[5]; for (int i = 0; i < circles.length; i++) { circles[i] = new Circle(); } ```

Step by step solution

Declare the array

To declare an array, specify the type of the elements the array can hold (in this case, Circle), followed by square brackets ([]), and finally, the name of the array. Let's create an array named "circles" that will hold five Circle objects: ```java Circle[] circles; ```

Set the size of the array and instantiate the elements

Arrays in Java have a fixed size, which is specified when initializing the array. We will initialize our array with a size of five. Then, we need to instantiate each object in the array: ```java circles = new Circle[5]; for (int i = 0; i < circles.length; i++) { circles[i] = new Circle(); } ``` The "new Circle[5]" expression initializes an array with a size of five elements. The following loop iterates through the array and creates a new Circle object for each element.

Final Solution

Combining all the steps, our final solution is the following statement that defines an array of five Circle objects: ```java Circle[] circles = new Circle[5]; for (int i = 0; i < circles.length; i++) { circles[i] = new Circle(); } ```
