NTT Data Interview Questions and Answers

Q1. What is Protocol in swift?
Ans. 
Protocols in Swift define a blueprint of methods, properties, and other requirements that a class, struct, or enum must adopt.
• Protocols are used to define a set of rules or capabilities that a type must conform to.

• They allow for code reuse and provide a way to define common behavior across different types.

• A type can adopt multiple protocols, enabling it to conform to multiple sets of rules.

• Protocols can require propert...read more

Q2. What is Dependency Injection.?
Ans. 
Dependency Injection is a design pattern where the dependencies of an object are provided externally rather than being created internally.
• Dependency Injection helps in achieving loose coupling between classes.

• It allows for easier testing and maintenance of code.

• There are three types of Dependency Injection: Constructor Injection, Setter Injection, and Interface Injection.

• Example: In iOS development, we can use Dependen...read more

Q3. What is Generics in swift.?
Ans. 
Generics in Swift allow you to write flexible and reusable code by creating functions, classes, and structures that can work with any type.
• Generics enable you to write code that can be used with different types, without duplicating code.

• You can define generic functions, types, and protocols to work with a wide range of types.

• Generics are particularly useful when working with collections, such as arrays and dictionaries...read more

Q4. What is Associate types ?
Ans. 
Associate types are a way to create a relationship between two types in Swift.
• Associate types are defined using the 'associatedtype' keyword.

• They are used in protocols to define a placeholder type that will be specified by the conforming type.

• The conforming type can provide its own concrete type for the associated type.

• This allows protocols to be more flexible and reusable.

• For example, a protocol for a container type c...read more

Q1. What is one problem that interfaces solve that abstract classes do not?
Ans. 
Interfaces allow multiple inheritance, abstract classes do not.
• Interfaces can be implemented by multiple classes, allowing for multiple inheritance.

Q3. Could you explain how the autowired annotation functions internally?
Ans. 
Autowired annotation in Spring framework injects dependencies automatically

Q4. How does Spring Boot determine which data source to use for application execution when multiple data sources are available and no specific profile has been defined?
Ans. 
Spring Boot uses @Primary annotation to determine which data source to use when multiple are available.
• Spring Boot uses the @Primary annotation to specify the primary bean to be used when multiple beans of the same type are present.

• If no specific profile is defined, Spring Boot will use the bean marked with @Primary as the default data source.

• Developers can also use @Qualifier annotation to specify which bean to use if...read more

Q5. What can you explain about the qualifier annotation?
Ans. 
Qualifier annotation is used in Spring framework to distinguish between beans of the same type.
• Qualifier annotation is used in Spring framework to resolve ambiguity when multiple beans of the same type are present.

• It is used in conjunction with Autowired annotation to specify which bean should be injected.

• For example, @Qualifier("myBean") can be used to specify a particular bean named 'myBean' to be injected.
