Question: What is the 'this()' constructor call in Java?

Answer: The 'this()' constructor call is used to invoke another constructor in the same class. It must be the first statement in the constructor if used.

Example:

class MyClass { MyClass(int x) { this(); /* other constructor code */ } 
MyClass() { /* default constructor code */ } }
