Select the correct answerWhat would be the behaviour if one parameterized constructor is explicitly defined?OptionsRuntime errorCompilation succeedsCompilation errorCompilation succeeds but at the time of creating object using default constructor, it throws compilation error
Solution
The correct answer is "Compilation succeeds but at the time of creating object using default constructor, it throws compilation error".
Here's why:
When you define a parameterized constructor for a class in a programming language like C++ or Java, the compiler does not automatically provide a default constructor (a constructor with no parameters). This means that if you try to create an object using a default constructor (i.e., without providing any arguments), the compiler will throw an error because it can't find a matching constructor.
So, while the compilation will succeed when you define a parameterized constructor, you will get a compilation error at the time of creating an object using the default constructor, unless you have explicitly defined a default constructor in your class.
