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
How many types are there in java?
The two basic data types in Java are primitives and objects. Primitives: byte, char, short, int, long, float, double, boolean Objects: Everything else.
Variables as object in java?
There are two main categories of variables in Java. They are primitive and non primitive. Primitive data types are the basic data types like int, float, char etc. These are not objects. The other non primitive data types are all types of Java Objects. Example: String, ArrayList etc.
Why c plus plus is not fully oop based?
C++ evolved from C and therefore retains the concept of primitive variables inherited from C, including int and char. In 100% OOP languages such as Java, these primitives would be implemented as objects. But in C++, they are primitive in nature. That is, they have no built-in methods such as .ToString() associated with them.
Why java not use int as a generic argument?
Only Objects can be used as generic arguments. Primitives Data Types (int, long, char ...) are not objects. But you can use Integer, an Object that wrap the data type int instead.
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.

What are properties in Javascript?
Like other object-oriented languages (JavaScript is technically not 'object-oriented'), JavaScript has objects, those objects have attributes or 'properties' which hold data

Can object extends?
objects are instances of class only and moreover objects are object reference variables extension of variables is meaningless so objects in java can't be extend
How does one define a Javascript class?
To define the class of a javascript code or string there are two to three or so main methods, one of these is to use it, and review the result, such as activating and using a function relative to to itself. Another is to use the objects Literals, the advantage to this is that Literals are a shorter way to define objects and arrays in JavaScript.

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)
Is c plus plus an object orinted language?
Yes, it is object-oriented, but it is not 100% object-oriented because it supports the concept of primitive variables (which it inherits from C) such as char, int and bool, as well as pointer variables. In a 100% object-oriented language, these primitives would be implemented as objects, as they are in C# and Java. C++ is best described as a hybrid of procedural, structured and object-oriented programming paradigms.
What are the categories of algebra?
the categories of algevra is the collection of objects, arrows,replacing the unknown value with a letter.
What are the Java Data Objects standards?
Member Variables
What is a example of a class is Javascript. Describe the properties and one method. Give two examples of objects of that class?
JavaScript is a prototype based object oriented language. This means that it doesn't have classes.
