Answer / Yatendra Pal Singh

In Java, both Zero Argument Constructor and Default Constructor serve the purpose of creating objects without explicit parameters. However, they have some differences:n1. Zero Argument Constructor - A zero-argument constructor is a constructor that doesn't take any arguments in its method signature. It is used to create an object with default initial values.n2. Default Constructor - By default, Java generates a no-argument constructor for every class. If you don't provide any constructors explicitly, the default constructor will be used when creating objects of that class.n3. Differences - The main difference lies in when they are generated: Zero Argument Constructors are user-defined, while Default Constructors can be either user-defined or automatically generated by the compiler if no constructors are defined.
