Are these interview questions helpful?
A R&D Engineer was asked
Q. Write a program to implement the singleton design pattern.
Ans. 

Singleton design pattern ensures only one instance of a class is created and provides a global point of access to it.

  • Create a private constructor to prevent direct instantiation of the class

  • Create a private static instance of the class

  • Create a public static method to access the instance

  • Ensure thread safety by using synchronized keyword or static initialization block

  • Example: Database connection manager

A R&D Engineer was asked
Q. How would you sort a list of alphanumeric values?
Ans. 

Sort a list of alphanumeric values.

  • Use a sorting algorithm to sort the array of strings.

  • If the values are case-insensitive, convert them to lowercase before sorting.

  • If the values contain numbers, use a natural sorting algorithm to sort them.

  • If the values contain special characters, consider their ASCII values while sorting.

A R&D Engineer was asked
Q. Design an immutable class.
Ans. 

An immutable class is a class whose instances cannot be modified after creation.

  • Make all fields private and final

  • Do not provide any setters

  • Make the class final so that it cannot be subclassed

  • If any mutable object is used as a field, return a copy of it instead of the original object
