- Q4. What is the garbage collector in Java?
- Ans.
Garbage collector in Java is a built-in mechanism that automatically manages memory by reclaiming unused objects.
Garbage collector runs in the background to identify and remove objects that are no longer needed.
It helps prevent memory leaks and optimize memory usage.
Examples of garbage collectors in Java include Serial, Parallel, CMS, and G1.
- Q5. What is a static variable in C?

Useful for maintaining state across function calls
- Q6. Can you explain the Singleton Class in Java?
- Ans.
Singleton class in Java ensures that a class has only one instance and provides a global point of access to it.
Singleton class is implemented by making the constructor private to prevent instantiation from outside the class.
It provides a static method to access the single instance of the class.
The instance is created only once and reused throughout the application.
Example: Logger class in Java can be implemented as a S...
- Q7. Can you write a SQL query that joins two tables A and B on the common attribute ID and selects records (ID_NAME) that have matching ID values in both tables?

- Q1. 1.introduce yourself
- Q2. 2.what is singleton pattern
- Ans.
Singleton pattern is a design pattern that restricts the instantiation of a class to one object.
Used when only one instance of a class is needed throughout the application
Provides a global point of access to the instance
Implemented using a private constructor and a static method to return the instance
Example: Database connection, Logger, Configuration settings
- Q3. 3.what is static variable
- Ans.
Static variable is a variable that retains its value even after the function execution is completed.
Declared with static keyword
Memory is allocated once and shared among all instances of the class or function
Can be accessed without creating an object of the class
- Q4. Oops concepts
- Q5. Write a query for delete
- Ans.
Query for deleting data from a database table.
Use the DELETE statement followed by the table name.
Add a WHERE clause to specify the condition for deleting specific rows.
Be careful when deleting data as it cannot be recovered.

- Q9. Write a program to check string is pallindrome or not
- Ans.
Program to check if a string is a palindrome or not.
Remove all spaces and convert to lowercase for case-insensitive comparison.
Compare the first and last characters, then move towards the center until all characters have been compared.
If all characters match, the string is a palindrome.
If any characters do not match, the string is not a palindrome.
- Q10. Explain time complexity
- Ans.
Time complexity refers to the amount of time taken by an algorithm to run as the input size increases.
It measures the efficiency of an algorithm.
It is usually expressed in Big O notation.
An algorithm with a lower time complexity is more efficient than one with a higher time complexity.
- Q11. What is garbage collection in java
- Ans.
Garbage collection in Java is an automatic memory management process.
It frees up memory by removing objects that are no longer in use.
It is performed by the JVM in the background.
It helps prevent memory leaks and improves performance.
There are different types of garbage collectors in Java, such as Serial, Parallel, CMS, and G1.
Example: int[] arr = new int[1000]; arr = null; // Garbage collector will remove the array fr

- Q3. Real time examples of Data structures?
- Ans.
Data structures are used to organize and store data in a computer program.
Arrays - used to store a collection of elements of the same data type
Linked Lists - used to store a collection of elements where each element points to the next element

Queues - used to store a collection of elements where the first element add...
- Q4. What is recursion?Explain it graphically?How compiler executed recursion?
- Ans.
Recursion is a process in which a function calls itself repeatedly until a base condition is met.
Recursion involves breaking down a problem into smaller subproblems and solving them recursively.
It uses a stack to keep track of function calls and their parameters.
Examples include factorial, Fibonacci sequence, and binary search.
Compiler executes recursion by allocating memory for each function call and storing the retur...
- Q5. Which data structure is used in recursion?
- Ans.
The data structure used in recursion is a stack.
Recursion uses a stack data structure to keep track of function calls.
Each time a function is called, its parameters and local variables are pushed onto the stack.
When the function returns, the values are popped off the stack.
This allows the program to keep track of where it is in the recursive process.
Examples of recursive algorithms that use a stack include depth-first
- Q6. Write any program of recursion and explain it using stack frames?
- Ans.
A program demonstrating recursion using factorial function.
Recursion is a technique where a function calls itself.
Factorial function is a classic example of recursion.
Each recursive call creates a new stack frame.
The base case is when the input is 1, and the function returns 1.
The final result is the product of all the recursive calls.
Example: factorial(5) = 5 * factorial(4) = 5 * 4 * factorial(3) = ... = 5 * 4 * 3 * 2
- Q7. Addition and Deletion of a node in binary tree?
- Ans.
Addition and Deletion of a node in binary tree
For addition, traverse the tree to find the appropriate position and add the new node as a leaf
For deletion, find the node to be deleted and replace it with its successor or predecessor
In case of deletion, if the node has two children, find the inorder successor and replace it with the node to be deleted
