Why Should You Define a Default Constructor in Java ?

In general, Java provides a default constructor with each class. But there are certain cases when we want to define our own version of default constructor.

When we want to construct an object with default values, we create our default constructor.

At times, we can mark the default constructor private. So that any other class cannot create an instance of our class. This technique is generally used in Singleton design pattern.
