Medullus Technologies Interview Questions and Answers

Yes, we can pass arguments in place of args in string[] args.

• Arguments can be passed directly as an array of strings.

• The number of arguments passed must match the size of the array.

• Example: public static void main(String[] args) can be called as main(new String[] {"arg1", "arg2"});

Python is a high-level, interpreted programming language known for its simplicity and ease of use.

• Python is used for web development, data analysis, artificial intelligence, and more.

• An array is a collection of elements of the same data type, accessed using an index.

• Two basic coding questions could be finding the sum of two numbers or reversing a string.

The given string can be reversed using recursion.

• Use a recursive function to reverse the string.

• The base case of the recursion would be an empty string.

• In each recursive call, remove the first character of the string and append it to the reversed substring.

stringBuilder and stringBuffer are both used to manipulate strings, but stringBuilder is faster and not thread-safe while stringBuffer is slower and thread-safe.

• Both classes are used to manipulate strings.

• stringBuilder is faster than stringBuffer.

• stringBuffer is thread-safe while stringBuilder is not.

• Use stringBuilder when you don't need thread-safety and performance is important.

• Use stringBuffer when you need thread-safety.

Yes, strings are immutable in most programming languages.

• Immutable means that once a string is created, it cannot be modified.

• Any operation that appears to modify a string actually creates a new string.

• This can lead to performance issues when working with large strings or in loops.

• Examples of languages with immutable strings include Java, Python, and Ruby.
