Can we call main () of a class from another class in Java?

Yes, we can call the main() method of a class from another class in Java, but it's generally not a recommended approach.

The main() method is a special method in Java that serves as the entry point of a Java program. When a Java program is executed, the main() method of the class that is specified as the program's starting point is called automatically by the Java Virtual Machine (JVM).

To call the main() method of a class from another class, we need to use the class name followed by the method name and any necessary arguments. For example, if we have a class named MyClass with a main() method, we can call it from another class like this:

MyClass.main(new String[] { });

However, it's generally not a recommended approach to call the main() method of a class from another class. The main() method is typically used as an entry point for the entire program, and it's usually designed to be called only once, at the beginning of the program's execution. If we call main() method of a class from another class, we may end up executing the same code multiple times, which can lead to unexpected behavior.

 

Instead of calling the main() method of a class from another class, we should design our programs to use separate methods or classes to perform specific tasks, and then call these methods or classes from the main() method as necessary. This will make our code more modular and easier to maintain.
