Can you store a class in an array?
Yes, since objects are also considered as datatypes (reference) in Java, you can create an array of the type of a particular class and, populate it with instances of that class.
What is an integer array?
Java Integer Array is a Java Array that contains integers as its elements. Elements of no other datatype are allowed in this array. In this tutorial, we will learn how to declare a Java Int Array, how to initialize a Java Int Array, how to access elements of it, etc.
How do you store an array of values?
Storing Data in Arrays. Assigning values to an element in an array is similar to assigning values to scalar variables. Simply reference an individual element of an array using the array name and the index inside parentheses, then use the assignment operator (=) followed by a value.
What kind of values can array store?
Arrays are classified as Homogeneous Data Structures because they store elements of the same type. They can store numbers, strings, boolean values (true and false), characters, objects, and so on.
Which data type can an array hold?
Can an array store different data types?
No, we cannot store multiple datatype in an Array, we can store similar datatype only in an Array.
What is integer array in C?
An array is a group (or collection) of same data types. For example an int array holds the elements of int types while a float array holds the elements of float types.
How do you declare an array of int values?
We declare an array in Java as we do other variables, by providing a type and name: int[] myArray; To initialize or instantiate an array as we declare it, meaning we assign values as when we create the array, we can use the following shorthand syntax: int[] myArray = {13, 14, 15};
How data is stored in array with example?
Example
- #include
- int main () {
- int n[ 11 ]; /* declaring an array comprising of 11 integers */
- int i,j;
- /* initialize elements of array n to 0 */
- for ( i = 0; i < 11; i++ ) {
- n[ i ] = i + 10; /* storing or initializing the array at location i with element i + 100 */
- }

What type of data is array?
The array data type is a compound data type represented by the number 8 in the database dictionary. Arrays store a list of elements of the same data type accessed by an index (element) number. The term array is synonymous with the terms list, vector, and sequence.
How many types of elements can array store?
The array cannot hold any more elements than its initial size. For example: int myArray[] = new int[5]; This snippet of code will create an array (on the “heap” or “free store” memory, using the new keyword) holding up to five integers.
Is array a data type?
In computer science, an array type is a data type that represents a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time during program execution. Such a collection is usually called an array variable, array value, or simply array.
