Core Java Programming Course- Static Keyword

The video tutorial explains the concept of the static keyword in programming, highlighting its use for class members and methods. It demonstrates how static fields belong to the class rather than any object, using a student class example. The tutorial shows how to create objects and assign values, illustrating the impact of static variables on multiple objects. It also covers accessing static members directly through the class name, emphasizing the shared nature of static variables across objects.

What is the primary characteristic of a static member in a class?

• It cannot be shared across objects.

• It can only be accessed by creating an object.

• It belongs to the class.

• It belongs to the object.

In the Student class example, what is initially set as the student's name?

• XYZ

• GHI

• ABC

• DEF

What happens when the 'name' variable in the Student class is changed to static?

• The name becomes private.

• The name is shared across all objects.

• Each object retains its own name.

• The name cannot be changed.

What is the effect of changing a variable to static in terms of object sharing?

• The variable becomes immutable.

• The variable is unique to each object.

• The variable is shared among all objects.

• The variable cannot be accessed.

How can static members be accessed in a class?

• By creating an object of the class.

• By declaring them as public.

• By using the class name directly.

• By using a special keyword.

When should you consider using static members in a class?

• When you want to make the variable immutable.

• When you want to prevent access to the variable.

• When you want to share a variable across multiple objects.

• When you want each object to have its own copy.

What is the advantage of accessing static methods using the class name?

• It allows for faster execution.

• It makes the method private.

• It requires less memory.

• It eliminates the need to create an object.
