Can we overload a main()
method in Java?
Yes, you can overload main method in Java. you have to call the overloaded main method from the actual main method.
Yes, you can.
The main
method in Java is no extra-terrestrial method. Apart from the fact that main()
is just like any other method & can be overloaded in a similar manner, JVM always looks for the method signature to launch the program.
The normal main
method acts as an entry point for the JVM to start
the execution of program.
We can overload the main
method in Java. But the program doesn’t
execute the overloaded main
method when we run your program, we need
to call the overloaded main
method from the actual main method only.
// A Java program with overloaded main()
import java.io.*;
public class Test {
// Normal main()
public static void main(String[] args) {
System.out.println("Hi Geek (from main)");
Test.main("Geek");
}
// Overloaded main methods
public static void main(String arg1) {
System.out.println("Hi, " + arg1);
Test.main("Dear Geek","My Geek");
}
public static void main(String arg1, String arg2) {
System.out.println("Hi, " + arg1 + ", " + arg2);
}
}
