Can an array can store infinite data of similar type?

Answer: Arrays can contain any type of element value (primitive types or objects), but you can’t store different types in a single array.

Can you have an infinite array?

Infinite arrays are rectangular arrays of infinite extent. In an infinite array, a single element called a unit cell, is repeated uniformly an infinite number of times along a plane.

How much data can an array store?

By default, the maximum size of an Array is 2 gigabytes (GB).

What can be stored in an array?

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. But once you define the type of values that your array will store, all its elements must be of that same type.

Can array store multiple data types?

No, we cannot store multiple datatype in an Array, we can store similar datatype only in an Array.

Can array store different types of data in Java?

You can store mutliple types of data in an Array, but you can only get it back as an Object. You can have an array of Objects: Object[] objects = new Object[3]; objects[0] = “foo”; objects[1] = 5; Note that 5 is autoboxed into new Integer(5) which is an object wrapper around the integer 5.

How do you find an element in an infinite array?

Basically, pick some number B and set A to 0, then check if the element you’re looking for is between A and B. If it is, perform the usual kind of binary search in these boundaries, otherwise set B=A and A=2*A and repeat. This will take O(log(M)), where M is the position of the element you’re looking for in the array.

Are can be created only for primitive data types?

No, arrays are not primitive datatypes in Java. They are container objects which are created dynamically. All methods of class Object may be invoked on an array. They were considered as reference data types.

Can array store any data types?

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. Elements in arrays can be of any data types (including arrays or structures).

How is array stored?

An array stores its elements in contiguous memory locations. If You created the array locally it will be on stack. Where the elements are stored depends on the storage specification.

Can we store object in array?

Storing Objects 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 array in programming?

To handle such situations, almost all the programming languages provide a concept called array. An array is a data structure, which can store a fixed-size collection of elements of the same data type. An array is used to store a collection of data,…

How to declare a single-dimensional array in C?

This is called a single-dimensional array. The arraySize must be an integer constant greater than zero and type can be any valid C data type. For example, now to declare a 10-element array called number of type int, use this statement − Here, number is a variable array, which is sufficient to hold up to 10 integer numbers.

How many floating-point values can an array hold?

Meaning, it can hold 5 floating-point values. It’s important to note that the size and type of an array cannot be changed once it is declared. You can access elements of an array by indices. Suppose you declared an array mark as above. The first element is mark [0], the second element is mark [1] and so on.

Is it possible to initialize an array during declaration?

It is possible to initialize an array during declaration. For example, You can also initialize an array like this. Here, we haven’t specified the size. However, the compiler knows its size is 5 as we are initializing it with 5 elements. Here’s how you can take input from the user and store it in an array element.
