HashMap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
Retrieving a value involves hashing...
Reverse a linked list by changing the direction of pointers.
Start with three pointers: current, previous, and next.
Iterate through the linked list, updating pointers to reverse the direction.
Return the new head of the reversed linked list.
Effective conflict management involves communication, empathy, and collaboration to resolve disagreements constructively.
Listen actively to understand the other person's perspective. For example, during a code review, ask for clarification on their suggestions.
Stay calm and composed, avoiding emotional reactions. If a team member disagrees with your approach, take a moment to breathe before responding.
Focus on the...

Yes, Java is platform independent due to its ability to compile code into bytecode that can run on any platform with a Java Virtual Machine (JVM).
Java code is compiled into bytecode which can run on any platform with a JVM
JVM acts as an abstraction layer between the Java code and the underlying platform
Java's 'write once, run anywhere' principle allows for platform independence
ApplicationContext is an interface for providing configuration information to an application.
ApplicationContext is the central interface in a Spring application for providing configuration information to the application.
It is responsible for instantiating, configuring, and assembling beans.
ApplicationContext can load bean definitions, wire beans together, and dispense beans upon request.
It provides a means for res...
Program to find duplicate strings in an array
Iterate through the array and store each string in a HashSet
If a string is already in the HashSet, it is a duplicate
Return a list of all duplicate strings found
Iterate through array to find 2nd largest number
Iterate through array and keep track of largest and second largest numbers
Handle edge cases like duplicates and empty array
Example: ['3', '5', '2', '7', '5'] should return 5 as the 2nd largest number
Java 8 introduced several new features including lambda expressions, functional interfaces, streams, and default methods.
Lambda expressions allow you to write code in a more concise way by replacing anonymous classes.
Functional interfaces are interfaces with a single abstract method, which can be implemented using lambda expressions.
Streams provide a way to work with sequences of elements and perform operations li...
AOT compiles code before runtime, JIT compiles code during runtime.
AOT stands for Ahead Of Time compilation, compiles code before execution
JIT stands for Just In Time compilation, compiles code during execution
AOT produces machine code that can be executed directly
JIT converts code into machine code as needed, optimizing performance
Examples: AOT - Angular, JIT - Java Virtual Machine
