Do all objects of the same class have the same methods?
Objects that belong to the same class have the same behaviors. That is, they have the same instance methods. Static variables and methods in a class are sometimes called class variables and class methods, since they belong to the class itself, rather than to instances of that class.

Does a class method have copies?
So no, objects don’t have a copy of the methods in their class. Every time you access Harry. getName a new callable object (the “method”) is built from scratch.
Does each class have its own copy of the code?
the code and data that make up the class. Each object of a class has its own copy of the class’s instance variables.
Which of these object class methods can generate a duplicate copy of the object?
clone() is a method in the Java programming language for object duplication. In Java, objects are manipulated by reference variables, and there is no operator to copy an object: the assignment operator duplicates the reference, not the object.
What is the best way to copy an object?
One method of copying an object is shallow copy where we allocate a new, uninitialized object and copy all the fields (attributes) from the original object into it.
How are methods stored in object properties?
Summary 1 Functions that are stored in object properties are called “methods.” 2 Methods allow objects to “act” like object.doSomething(). 3 Methods can reference the object like this.
Is copying an object not trivial?
The design goal of most objects is to give the appearance of being made from a monolithic block, even though most are not. Since objects are made up of several different parts, copying becomes non-trivial. There are several strategies to deal with this problem.
What happens when you copy an object in Java?
This does not always result in the desired behavior when the field’s value is a reference to an object, since it copies the reference and thus references the same object as an original object. Referenced objects are shared, so if one object is modified, the change is visible in the other. 2. Deep Copy
