Output:

Explanation:
• In this example, we have a class MyClass with three constructors.
• The first constructor calls the second constructor using this(0, 0), which initializes x and y to 0.
• The second constructor calls the third constructor using this(x, y, “Default”), which initializes x, y, and name.
• The third constructor initializes all the attributes x, y, and name based on the provided arguments.

• In the main method, we create an instance of MyClass using the first constructor, which in turn triggers the
chain of constructors.
• The display method is called to print the object’s attributes.
