Considering the responses below, which one(s) would be a correct response (Select all that apply)?

**Select all the responses below that could be used to define an object**

2. Method signatures

3. something you wear

8. There are no objects in Java

9. Class object is the root of the class hierarchy

Explanation / Answer

In terms of programming, object is an instance of a class. Now what it means is, when you define a class, memory is not allocated for its data members. But as soon as you create an object, a memory area is allocated for its data memebers.

object is an instance of class.

An object can be a variable, a data structure, or a function. In the class-basedobject-oriented programming paradigm, "object" refers to a particular instance of a class where the object can be a combination of variables, functions, and data structures.

For example, an object in computers might have something to do with variables or constants [none tangible]. In real world, it might be defined as a solid material, doesn’t matter if its transparent, translucent or opaque, but usually is tangible.

Take an example of a pen .Now ,this pen is an object of the class “something to write with”.This class includes other objects like pencil,mechanical pencil,brush etc. But ,this particular pen could be considered a class where a Reynolds pen ,add gel and parker pen can be considered it's object.
