Question

Can a main   method of class be invoked in another class in java   e g    class class1     public static void main String   args            class class2     public static void main String   args         class1 main

Sure  Here s a completely silly program that demonstrates calling main recursively   public class main       public static void main String   args                for  int i   0  i  lt  args length    i                        if  args i                                       args i                        System out println  args length - i      left                    main args

Yes as long as it is public and you pass the correct args  See this link for more information  http   www codestyle org java faq-CommandLine shtml mainhost

If you want to call the main method of another class you can do it this way assuming I understand the question  public class MyClass        public static void main String   args             System out println  quot main   method of MyClass quot            OtherClass obj   new OtherClass             class OtherClass        public OtherClass                 Call the main   method of MyClass         String   arguments   new String     quot 123 quot            MyClass main arguments

yes  but only if main is declared public

if I got your question correct     main   method is defined in the class below     public class ToBeCalledClass      public static void main  String args             System out println  I am being called             you want to call this main method in another class   public class CallClass       public void call           ToBeCalledClass main null

As far as I understand  the question is NOT about recursion  We can easily call main method of another class in your class  Following example illustrates static and calling by object  Note omission of word static in Class2  class Class1      public static void main String   args            System out println  this is class 1                 class Class2      public void main String   args            System out println  this is class 2                 class MyInvokerClass      public static void main String   args             System out println  this is MyInvokerClass            Class2 myClass2   new Class2            Class1 main args           myClass2 main args                 Output Should be      this is wrapper class       this is class 1      this is class 2
