- Q1. Can we overload main method?
- Ans.
No, the main method in Java cannot be overloaded.
The main method in Java is the entry point of a program and must have a specific signature: public static void main(String[] args).
Attempting to overload the main method by changing the number or type of parameters will result in a compilation error.
Instead of overloading the main method, you can create additional methods in the same class to perform different tasks.
