Question

When a program does not contain any constructor, Java compiler provides:

पर्याय

• a Null constructor

• an overloaded constructor

• a default constructor

• a parameterized constructor

Answer 1

a default constructor

Explanation:

• The Java compiler assumes you still need to create objects. It secretly inserts an empty constructor with no parameters during compilation.
• This default constructor initializes all instance variables to their default values (such as 0 for numbers, false for booleans, and null for objects).
