Can we overload a main   method in Java

User · Answer

Yes  by method overloading  You can have any number of main methods in a class by method overloading  Let s see the simple example   class Simple      public static void main int a       System out println a              public static void main String args         System out println  main   method invoked        main 10                 It will give the following output   main   method invoked 10

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  amp  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           Valid variants of main   in Java

You can overload the main   method  but only public static void main String   args  will be used when your class is launched by the JVM  For example   public class Test       public static void main String   args            System out println  main String   args                public static void main String arg1            System out println  main String arg1                public static void main String arg1  String arg2            System out println  main String arg1  String arg2               That will always print main String   args  when you run java Test     from the command line  even if you specify one or two command-line arguments   You can call the main   method yourself from code  of course - at which point the normal overloading rules will be applied   EDIT  Note that you can use a varargs signature  as that s equivalent from a JVM standpoint   public static void main String    args

Yes  main method can be overloaded  Overloaded main method has to be called from inside the  public static void main String args     as this is the entry point when the class is launched by the JVM  Also overloaded main method can have any qualifier as a normal method have

YES  you can overload main   But to be clear -- although you can overload main  only the version with the standard signature will be executable as an application from the command line  e g public static void main String a String    args      some code   2 public static void main String   args    JVM will call this method to start     some code

yes we can overload main method  main method must not be static main method

Yes you can Overload main method but in any class there should be only one method with signature public static void main string args    where your application starts Execution  as we know in any language Execution starts from Main method   package rh1   public class someClass         public static void main String    args                System out println  Hello world             main  d            main 10             public static void main int s                 System out println  Beautiful world              public static void main String s                System out println  Bye world

Yes a main method can be overloaded as other functions can be overloaded One thing needs to be taken care is that there should be atleast one main function with  String args     as arguments  And there can be any number of main functions in your program with different arguments and functionality Lets understand through a simple example   Class A   public static void main String   args    System out println  This is the main function     A object  new A    object main  Hi this is overloaded function     Calling the main function    public static void main String argu        duplicate main function   System out println  main String argu           Output  This is the main function Hi this is overloaded function

Yes  you can overload main method in Java  But the program doesn t execute the overloaded main method when you run your program  you have to call the overloaded main method from the actual main method   that means main method acts as an entry point for the java interpreter to start the execute of the application  where as a loaded main need to be called from main

Yes   main     method can be overloaded  I have tried to put in some piece of code to answer your question   public class Test  static public void main  String    args                             System out println   In the JVMs static main                     main  5  6  7         Calling overloaded static main method                 Test t   new Test                     String    message       Subhash    Loves    Programming                     t main 5                   t main  6  message                       public static void main  int     args                             System out println   In the static main called by JVM s main                     for  int val   args                                             System out println  val                                         public void main  int x                             System out println   1  In the overloaded  non-static main with int with value     x                       public void main  int x  String    args                             System out println   2  In the overloaded  non-static main with int with value     x                    for   String val   args                                             System out println  val                                    Output     java Test In the JVMs static main In the static main called by JVM s main 5 6 7 1  In the overloaded  non-static main with int with value 5 2  In the overloaded  non-static main with int with value 6 Subhash Loves Programming     In the above code  both static-method as well as a non-static version of main methods are overloaded for demonstration purpose  Note that  by writing JVMs main  I mean to say  it is the main method that JVM uses first to execute a program

Yes According to my point of view  we are able to overload the main method but method overloading that s it  For Example   class main overload       public static void main int a            System out println a             public static void main String args              System out println  That s My Main Function            main 100             In This Double Back slash Step  I am just calling the main method

Yes u can overload main method but the interpreter will always search for the correct main method syntax to begin the execution   And yes u have to call the overloaded main method with the help of object   class Sample  public void main int a int b   System out println  The value of a is     a     public static void main String args     System out println  We r in main method    Sample obj new Sample    obj main 5 4   main 3     public static void main int c   System out println  The value of c  is    c        The output of the program is  We r in main method The value of a is 5 The value of c is 3
