1,905 PointsClasses and Objects, same or different ?
I understand thoroughly about the class and new instance often addressed as object of that class. But my question is why it is written as :- OBJECTS> String, Random, Activity and TextView when they all are classes. String, Random and Activity are objects or are they also called classes ? if Yes, then why ?
Confused ?????

3,944 PointsTo make it simple and easy to understand. I will put down a real life example of objects classes and method.
Dog is an object, Breed is a class, and Barking is a method.
So every object has class and method.

So for example if you have a class you have made called vegetable you can instantiate it (create an instance of it) and use it's various different functions and methods.
I hope this was helpful. Feel free to ask any more questions.

1,905 PointsI was writing a code for random number generation designed by Ben. The code is below:-
Random randomGenerator = new Random(); // Random is a class and a new instance is made
but there is a Presentation chart, which says : Random, String and Activity are objects
Confused ?????

13,564 PointsRandom, String and Activity are actually all classes but you can create a new instance of these classes and that instance is known as an object!
Random randomGen = new Random();
Random is the class and the new instance of that class (or the object) is called randomGen.
