Array

What is an array?

• A data structure used to store a collection of data

• A loop used to iterate through a collection of data

• A function used to manipulate a collection of data

• A variable used to store a single piece of data

Why do we use arrays in programming?

• To store multiple data of the same type in a single variable

• To perform mathematical calculations

• To create loops and conditions

• To print output on the console

How do we create an array in Java?

• By declaring a variable with square brackets and specifying the size

• By using a for loop to assign values to each element

• By using a function to generate random values

• By assigning values directly to the variable

How do we access elements in an array?

• By using the index of the element

• By using a for loop to iterate through each element

• By using a function to search for a specific value

• By assigning a variable to the array

What is the index of the first element in an array?

• 0

• 1

• -1

• 10

How can we print all the elements in an array?

• By using a for loop to iterate through each element

• By using a while loop to check each element

• By using a function to display the array

• By assigning a variable to the array

What is an example of a multidimensional array?

• An array of arrays

• An array with different data types

• An array with a variable size

• An array with only one dimension

How do we access elements in a multidimensional array?

• By using multiple indexes

• By using a for loop to iterate through each element

• By using a function to search for a specific value

• By assigning a variable to the array

What is the purpose of using arrays?

• To store and process large amounts of data efficiently

• To perform complex mathematical calculations

• To create loops and conditions

• To print output on the console

What is the index of the last element in an array?

• The size of the array minus one

• The size of the array

• 1

• 0
