Truncate removes all records from a table, while delete removes specific records. Drop deletes the table itself.
Truncate is faster than delete as it does not log individual row deletions.
Delete can be rolled back, while truncate cannot be rolled back.
Drop removes the table structure along with all its data.
Example: TRUNCATE TABLE table_name;
Example: DELETE FROM table_name WHERE condition;
Example: DROP TABLE table_name;
The 4 pillars of Java are encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Inheritance: Allows a class to inherit properties and behavior from another class.
Polymorphism: Ability of an object to take on many forms.
Abstraction: Hiding the implementation details and showing only the necessary features of an object.
