Access specifiers or modifiers define the access of a particular class, method, or variable to the other parts of the application. There are mainly 3 access specifiers – Public, Private, and Protected.

7. How do you achieve multiple inheritances in Java?

The only way to implement multiple inheritances is to implement multiple interfaces in a class. In Java, one class can implement two or more interfaces. As all methods declared in interfaces are implemented in the class, this does not cause any ambiguity.

8. What is the difference between compiler, interpreter, and assembler?

One of the key differences is – The compiler converts the whole high-level language program to machine language at a time. On the other hand, an interpreter converts high-level language programs to machine language line by line. An assembler converts assembly language programs to machine language.

9. Difference Between Primary Key and Unique Key

• Primary Key: In the need of a primary key there must be at least one key at the table and the use of this key helps in blocking the duplicate and also the null value.
• Unique Key: Whereas, in the unique key process, there can be more than one key in the table and here it will block the duplicated value and will rather accept the null value.

10. What are constraints in SQL?

Constraints in SQL are the limits or rules that we can apply to the different types of data in a given table. Constraints are used to ensure the accuracy and reliability of the data in the table.

• NOT NULL: This particular constraint informs us that one cannot store a null value within a column.
• UNIQUE: When specified with a column, this constraint informs that all the values in a given column must be unique.
• PRIMARY KEY: A primary key is a field that can uniquely identify each row in a table. This is typically used to specify a field in a table as the primary key.
• FOREIGN KEY: A Foreign key is a field that can uniquely identify each row in another table.
• CHECK: This constraint helps us to validate the values of a column to attain a particular condition.
• DEFAULT: This constraint gives a default value for the column when the user does not specify a value.

11. What is DBMS?

DELETE FROM Table_name WHERE fieldname1 NOT IN (SELECT MAX(fieldname1) FROM
Table_name GROUP BY FieldName2, FieldName2);

14. What is a Foreign Key?

When we relate two tables then the primary key of the first table is declared as the foreign key for another table.

Common Language Specification (CLS) helps the application developers to use the components that are inter-language compatible with certain rules that come with CLS. It also helps in reusing the code among all of the .NET-compatible languages.

16. Explain role-based security in .NET

Role-based security is used to implement security measures in .NET, based on the roles assigned to the users in the organization. In the organization, authorization of users is done based on their roles. For example, windows have role-based access like administrators, users, and guests.

17. What is a delegate in .NET?

• A delegate is a .NET object which defines a method signature and it can pass a function as a parameter. Delegate always points to a method that matches its specific signature. Users can encapsulate the reference of a method in a delegate object.
• When we pass the delegate object in a program, it will call the referenced method. To create a custom event in a class, we can make use of delegate.
