Can you overload main() method in Java?
Yes, in Java, you can overload the main() method, which means that you can define multiple main() methods in a class with different parameter lists.What is Method overloading
Method overloading is a feature in Java that allows a class to have multiple methods with the same name but different parameters. In other words, you can define multiple methods with the same name in a single class as long as their parameter lists differ in the number, type, or order of their parameters.Overload main() method in Java
The JVM looks for the main() method with the signature public static void main(String[] args) to start the program. However, you can define additional main() methods with different parameter lists, and these methods can be called from within the program like any other method.
Following program is a class that defines two main() methods:
public class MyClass {
public static void main(String[] args) {
System.out.println("First main method");
}
public static void main(int x) {
System.out.println("Second main method");
}
}
In this example, the first main() method takes a String array as a parameter, and the second main() method takes an integer parameter. Both methods can be called from within the program, like this:
public class Main {
public static void main(String[] args) {
MyClass.main(args); // Calls the first main() method
MyClass.main(10); // Calls the second main() method
}
}
However, it is important to note that only the public static void main(String[] args) method is used by the JVM to start the program. Therefore, any additional main() methods that you define will need to be called explicitly from within the program.
