One of the common doubts among Java beginners while learning the overloading and overriding concept is, whether it's possible to overload the main in Java? Can you override the main method in Java? How will JVM find if you change the signature of the main method as part of the method overloading? etc. These are good questions and show the curiosity and application of knowledge of students, so if you are the tutor you must answer these questions. If you don't know the answer to this question, don't worry, just read this article till the end and you will find the answer yourself. I have tried to explain in simple words but if you still can't get it, feel free to comment and I will try to help you personally. The short answer to, can we overload the main method in Java is Yes, you can overloading, nothing stops from overloading, but JVM will always call the original main method, it will never call your overloaded main method. You will learn this in little more detail later, now coming to the next question, can you override the main method in Java? the answer is No because the main is a static method and the static method cannot be overridden in Java. In order to answer this question understanding of overloading and overriding is necessary. You should know that overloading takes place at compile time and overriding takes place at runtime. You should also be familiar with the rules of method overloading and overriding in Java. Though main() is a special method because it's the entry point of your Java application, it follows the same rule of method overriding and overloading as any other method. In this article, you will learn how to overload the main method to see whether JVM calls the original, standard main with string argument or not. Overloading the main method in Java Here is how you can overload the main method in Java. This is just one way, you can create as many versions of the main as you want, but you must make sure that the method signature of each main is different. You can change the method signature by changing the type of argument, the number of arguments, or the order of arguments. The best practice to overload a method or constructor is by changing the number of arguments, or types of arguments. Overloading methods just by changing the order of arguments may create confusion and increase the chance of calling the wrong method. It's worth remembering that, In Java, it's not possible to overload the method by just changing the return type. Code Example of Overloading Main Method in Java /** * Java Program to show that you can overload main method in Java * but you cannot override main method. * * @author Javin Paul */ public class Helloworld { /** * Standard main method, JVM will only call this method * even if you provided multiple overloaded version. * */ public static void main(String[] args) { System.out.println("Inside main(String[] args) method ...."); } /** * An overloaded main method which accepts Integer[] instead of * String[] as argument. * @param args */ public static void main(Integer[] args){ System.out.println("Inside main(Integer[] args) method ...."); } /** * Another overloaded main method which accepts Double[] instead of * String[] as argument. * @param args */ public static void main(Double[] args){ System.out.println("Inside main(Double[] args) method ...."); } } Output Inside main(String[] args) method .... In this example, you can see that we have two main methods, one accepts String array as an argument and the other accept Integer array as an argument, but you can see that when you run our program from the command line, only the main method with string array as an argument is called. There was no error, no ambiguity, JVM will always call this main method, no matter how many overloaded main methods you will put on this class. Then questions come how do you call your overloaded main? Well, you can call it just like any other method. Simply calling main(new int[]{1, 2, 3}) from the original main method will invoke your overloaded main with integer array as an argument. Since there is no compilation error, it proves that you can overload the main method in Java. Regarding Overriding we have already proven that the static method cannot be overridden, they can only be hidden. See that post to learn this concept by following an example. In short, the main method can be overloaded but cannot be overridden in Java. That's all about overloading and overriding the main method in Java. Now you know that it's possible to overload main in Java but it's not possible to override it, simply because it's a static method. Execution of Java program has no impact on overloading main because JVM always calls the original main method and if it doesn't found in class then it throws java.lang.NoSuchMethodError: main Exception in thread "main" error at runtime.
