Question

How can you create actual objects for an array of object references?

a) By using a for loop
b) By using a while loop
c) By using an if statement
d) By using a switch statement

Answer 1

To create actual objects for an array of object references, you could use a for loop or a while loop to iterate over the array and assign a new object to each element.

Step-by-step explanation:

To create actual objects for an array of object references, you can use any kind of loop structure that iterates through each element of the array and assigns a new object to it. The correct answers could be both a) By using a for loop and b) By using a while loop. An if statement and a switch statement are not typically used for iterative object creation because they do not provide a mechanism for iterating over a sequence or collection.

Here is an example using a for loop:

for (int i = 0; i < myArray.length; i++) {
myArray[i] = new MyObject();
}

And here's how you could do it with a while loop:

int i = 0;
while (i < myArray.length) {
myArray[i] = new MyObject();
i++;
}

These loops ensure that a new object is created and assigned to each element of the object reference array. The key is the repetition structure that a for loop or a while loop provides, allowing the creation of multiple objects in an automated and efficient manner.
