Should element in an array must be of primitive data type?
No, it can be array, structure or union as well.
How many data types can the elements of an array have?
Depends on your language. Assuming java: If you make it an Object[] then it can contain any object For primitive types you must either make a primitive type array, ie double[], char[] which can contain only those primitives, or creater an Object[] and use primitive wrapper objects ie java.lang.Integer etc.
Why object array called universal array?
Object array is called universal array because it can store multiple variables of the same type
Why should all of the elements in an array have the same data type?
Yes all of the elements in array must be the same type. Because when you define an array you specify the type of data it will hold. Examples in C: int IntArray[10]; // an array of 10 integers double FloatArray[20]; // array of 20 double floating point numbers
Create an array of 10 elements in java?
to create a new Java array use typeName[] arrayName = new typeName[10]; This gives an array with 10 elements. To set the elements you can use arrayName[index] = value; Remember that the index number starts at 0, so the array will only go to index 9. You can also declare the contents when the array is created typeName[] arrayName = {value1, vaue2, ...} The values used in the array must be objects. In java 5+ you can use primitive types with no concern due to auto-boxing.

What is the difference between an array and structure?
An array is a collection of related data elements of same type.Structure can have elements of different types.An array is a derived data type.A structure is a programmer-defined data type.A struct can contain multiple data types, whereas an array can not.
Why object array called universal array?
Object array is called universal array because it can store multiple variables of the same type
What data type can be used to represent 1000000 elements in an array?
An array.

Are arrays objects?
Yes. Arrays are objects in Java that store multiple variables of the same type. Arrays can hold either primitives or object references, but the array itself will always be an object on the heap, even if the array is declared to hold primitive elements. In other words, there is no such thing as a primitive array, but you can make an array of primitives
What an array?
An array is an aggregate of data elements of the same type. Arrays are allocated in contiguous memory. An element of an array can be another array type, also known as a multi-dimensional array.
What conditions must be satisfied by the entire elements of any given array?
All elements of any given array must satisfy the same data type requirement, meaning they should be of the same data type for the array to be well-defined and properly utilized.
What distinguishes an array from a structure?
Am array is an aggregate of elements that must be of the same type. A structure is an aggregate of elements (members) that can be of different types.
How do you accept an array in java?
Arrays are objects in Java that store multiple variables of the same type. Arrays can hold either primitives or object references, but the array itself will always be an object on the heap, even if the array is declared to hold primitive elements. In other words, there is no such thing as a primitive array, but you can make an array of primitives. Arrays are declared by stating the type of element the array will hold, which can be an object or a primitive, followed by square brackets to the left or right of the identifier. Declaring an array of primitives: int[] Values; // brackets before name (recommended) int Values []; // brackets after name (legal but less readable)
