  • Ans. 

    The task is to determine the number of distinct ways to climb from the 0th to the Nth stair, where you can climb one or two steps at a time.

    • Use dynamic programming to solve this problem efficiently.

    • Define a recursive function to calculate the number of ways to reach each stair.

    • Consider base cases for 0 and 1 stairs, and then use the recursive formula to calculate for N stairs.

    • Use modulo 10^9+7 to handle large numbers a...

  • Q2. What are the various access specifiers in Java?
  • Ans. 

    Access specifiers in Java control the visibility of classes, methods, and variables.

    • There are four access specifiers in Java: public, private, protected, and default.

    • Public: accessible from any other class.

    • Private: accessible only within the same class.

    • Protected: accessible within the same package and subclasses.

    • Default: accessible only within the same package.

  • Q3. How many types of memory areas are allocated by the JVM?
  • Ans. 

    JVM allocates 5 types of memory areas: Method Area, Heap, Stack, PC Register, and Native Method Stack.

    • Method Area stores class structures, method data, and runtime constants.

    • Heap is where objects are allocated and memory for new objects is dynamically allocated.

    • Stack stores local variables and partial results, and each thread has its own stack.

    • PC Register holds the address of the JVM instruction currently being execute...

  • Q4. What do you mean by data encapsulation?
  • Ans. 

    Data encapsulation is the concept of bundling data with the methods that operate on that data, restricting access to the data from outside the bundle.

    • Data encapsulation is a fundamental principle of object-oriented programming.

    • It allows for the data to be hidden and only accessed through the defined methods.

    • Encapsulation helps in achieving data security and prevents accidental modification of data.

    • Example: In a class r...

  • Q5. Can static methods be overridden?
  • Ans. 

    No, static methods cannot be overridden in Java.

    • Static methods belong to the class itself, not to any specific instance of the class.

    • Subclasses can have static methods with the same signature as the parent class, but they are not considered overridden.

    • Example: Parent class has a static method 'display()', and subclass also has a static method 'display()'. These are two separate methods, not an override.

  • Q1. What is dependency injection?
  • Ans. 

    Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.

    • Allows for easier testing by providing mock dependencies

    • Promotes loose coupling between components

    • Improves code reusability and maintainability

    • Examples: Constructor injection, Setter injection, Interface injection

  • Answered by AI
  • Q2. What is the purpose of using @ComponentScan in class files?
  • Ans. 

    @ComponentScan is used in class files to enable component scanning for Spring beans.

    • Enables Spring to automatically detect and register Spring components (beans) within the specified package(s)

    • Reduces the need for manual bean registration in configuration files

    • Can specify base packages to scan for components, or use default behavior to scan the current package and its sub-packages

  • Answered by AI
  • Q3. Can we override or replace the embedded Tomcat server in Spring Boot?
  • Ans. 

    Yes, we can override or replace the embedded Tomcat server in Spring Boot.

    • Spring Boot allows for customization of embedded servers by excluding the default server dependency and adding a different server dependency.

    • For example, to replace Tomcat with Jetty, exclude Tomcat and add Jetty dependencies in the pom.xml file.

    • Configuration properties can also be used to customize the embedded server in Spring Boot applications

  • Answered by AI
  • Q4. What is the starter dependency of the Spring Boot module?
  • Ans. 

    The starter dependency of the Spring Boot module is spring-boot-starter.

    • The starter dependency provides a set of common dependencies for a specific type of application.

  • Q5. What is Hibernate caching?
  • Ans. 

    Hibernate caching is a mechanism used to improve the performance of applications by reducing the number of database queries.

    • Hibernate caching stores frequently accessed data in memory to reduce the need for repeated database queries.

    • First-level cache is associated with the Session object and is enabled by default.

  • Ans. 

    Hibernate provides optimistic and pessimistic concurrency control strategies.

    • Optimistic concurrency control: Uses versioning or timestamp to check for concurrent updates.

    • Examples: @Version annotation for optimistic concurrency, LockMode.UPGRADE for pessimistic concurrency.
