Advanced Software Developer Interview Questions and Answers

Check if a string is a palindrome by comparing characters from start and end.

• Iterate through the string from start and end simultaneously to check if characters match.

• Handle corner cases like empty string, single character string, and strings with spaces or special characters.

• Examples: 'madam' is a palindrome, 'hello' is not a palindrome.

Java uses default methods to handle the diamond problem by allowing interfaces to have method implementations.

• Java allows interfaces to have default methods, which provide a default implementation for a method in case multiple interfaces define the same method.

• If a class implements two interfaces with the same default method, the class must override the method to provide its own implementation.

• Example: interface A { default void method() { System.out.println('A'); } } interfa...read more

Docker is a platform for developing, shipping, and running applications in containers, ensuring consistency across environments.

• Docker containers are lightweight and share the host OS kernel, making them more efficient than traditional VMs.

• Docker images are read-only templates used to create containers; they can be versioned and shared via Docker Hub.

• Docker Compose allows defining and running multi-container applications using a simple YAML file.

• Docker Swarm provides native c...read more

Debugging code involves identifying, isolating, and fixing errors to ensure software functions as intended.

• Use print statements to track variable values and program flow.

• Utilize a debugger tool to step through code line by line, examining state.

• Check error logs for stack traces that indicate where the issue occurred.

• Write unit tests to verify that individual components work correctly.

• Isolate the problematic code by commenting out sections to narrow down the source of the bug.
