Infosys Technology Analyst Interview Questions and Answers for Freshers

Boxing is the process of converting a value type to a reference type, while unboxing is the process of converting a reference type to a value type.

• Boxing is done implicitly by the compiler when a value type is assigned to a reference type variable.

• Unboxing requires an explicit cast from the reference type to the value type.

• Boxing and unboxing can impact performance as they involve memory allocation and copying of data.

Garbage collection is a process in programming where the system automatically reclaims memory occupied by objects that are no longer in use.

• Garbage collection helps prevent memory leaks by automatically freeing up memory that is no longer needed.

• It is commonly used in languages like Java, C#, and Python.

• Garbage collection can be either automatic or manual, with automatic being the most common approach.

An immutable class is a class whose instances cannot be modified after creation, ensuring data integrity and thread safety.

• Immutable classes prevent changes to their state after creation, e.g., String in Java.

• They often provide methods to return new instances with modified values, e.g., LocalDate in Java.

• Immutable objects are inherently thread-safe, reducing synchronization issues.

• Commonly used in functional programmin...read more
