Fujitsu Interview Questions, Process, and Tips

Dependency Injection is a design pattern in which 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

In Java, exceptions can be handled using try-catch blocks to catch and handle specific exceptions.

• Use try-catch blocks to catch exceptions and handle them gracefully

• Use multiple catch blocks to handle different types of exceptions

• Use finally block to execute code regardless of whether an exception is thrown or not

• Throw custom exceptions using throw keyword

map transforms each element in a stream, while flatMap transforms each element into multiple elements

• map applies a function to each element in a stream and returns a new stream of the results

• flatMap applies a function that returns a stream for each element in the original stream, then flattens the streams into a single stream

• Example: map - stream.map(x -> x * x), flatMap - stream.flatMap(str -> Arrays.stream(str.split(

ConcurrentModificationException occurs when a collection is modified while iterating over it.

• Use Iterator to iterate over the collection instead of foreach loop.

• If modification is necessary, use Iterator's remove() method instead of collection's remove() method.

• Consider using synchronized collections or ConcurrentHashMap to avoid ConcurrentModificationException.

I choose Python as my coding language.

• Python is a high-level, interpreted programming language known for its simplicity and readability.

• It supports multiple programming paradigms like procedural, object-oriented, and functional programming.

• Python has a large standard library and a thriving community, making it easy to find resources and support.

• Examples: print('Hello, World!'), for i in range(5): print(i)

An array is a data structure that stores a collection of elements of the same type. A string is a sequence of characters. Swapping numbers involves exchanging the values of two variables. A palindrome number reads the same forwards and backwards.

• An array can store multiple values of the same data type, accessed by index.

• A string is a sequence of characters enclosed in quotes, like 'hello'.

• Swapping numbers involves usin...read more

To troubleshoot network issues, start by checking physical connections, verifying network settings, testing connectivity, and analyzing network traffic.

• Check physical connections (cables, ports, etc.)

• Verify network settings (IP address, subnet mask, gateway, DNS)

• Test connectivity using tools like ping, traceroute, and netcat

• Analyze network traffic with tools like Wireshark or tcpdump

LDAP can be used to manage user accounts by storing user information in a centralized directory.

• Set up LDAP server and configure it to store user account information

• Use LDAP client tools to manage user accounts such as creating, modifying, or deleting accounts

• Authenticate users against LDAP server for access control

• Implement LDAP schema to define attributes and object classes for user accounts
