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

How do you handle object array?
Exactly as you would any other type of array. An object's size is determined in the same way a structure's size is determined, by the sum total size of its member variables, plus any padding incurred by alignment. However, you cannot create arrays of base classes. Arrays of objects can only be created when the class of object is final; a class that has a private default constructor, otherwise known as a "leaf" class. This is because derived classes can vary in size; array elements must all be the same size. To create an array of base classes you must create an array of pointers to those base classes instead. Pointers are always the same size (4 bytes on a 32-bit system). Static arrays are ideally suited to arrays of leaf objects where the number of objects never changes, or the maximum number of objects is finite and fixed. Although you can use dynamic arrays of leaf objects, you will incur a performance penalty every time the array needs to be resized, because every object's copy constructor must be called during the reallocation. Dynamic arrays are better suited to arrays of pointers to objects -- only the pointers need to be copied during resizing, not the objects they point to.
How do you find the difference between two arrays in Java?
for arrays you can list the different arrays and what attributes that you give to them.
Arrays whose size can be altered are known as?
Arrays whose size can be altered are known as dynamic arrays.
What do we call the numbers that cannot be arranged into 2-row arrays?
we can call the number that cannot be arranged into 2- row arrays multiple arrays.
Can element of character arrays be accessed in the same way as the elements of a numeric arrays?
Yes, it can.
Why are matrices used for representation while programming?
Let me correct you: two-dimensional arrays are used in programming to represent matrices. (Matrices are objects of mathematics, arrays are objects of programming.)
What is the importance of foreach loop in php?
The foreach construct simply gives an easy way to iterate over arrays. Foreach works only on arrays (and objects).
How do you do a division arrays?
Division arrays are typically done by dividing the total number of objects by the number of rows. These can come in the form of blocks or circles arranged in a specific number.
How arrays are useful?
Arrays hold objects in a programming language. For example, they could hold a list of names. You can sort or call up any of the names now that they are in an array easily.
Is an array is a collection of characters that can be fixed or variable?
No. An array is a collection of objects of any type, such as doubles, not just characters. You can even have arrays of arrays, or arrays of structs. In C, the size of an array is fixed, but it is possible to write code that will allow you to manually make it variable in size.

What is the PHP foreach construct used for?
The PHP foreach construct is used to iterate over arrays. This is done in the field of mathematics. It will issue errors when one tries to use it as a variable instead of arrays and objects.
What are arrays in math?
I asked the same darn thing when I was in 3rd grade.An array is a arrangement of objects in rows and columns!!!
How many data types are there in PHP?
The data types are grouped into this categories: Booleans Integers Floating point numbers Strings Arrays Objects
What is multidimentional array?
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.

What is a PHP function that can sort arrays by other arrays?
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
