The Java Runtime Environment invokes main methods.
Java's main function denotes the entry point into the execution of your program.
The main function. Every program must have a main function and it must be declared static.
the main function or main method is the first method that gets invoked when you try to run a java application. Any class that has a main method can be executed in a standalone fashion. A typical main method would look like below: public static void main(String[] args) { … // code goes here }
// C int main(int argc, char** argv) { return 0; } // Java class MainClass { public static void main(String[] args) { } } Differences: * Java main method must be in a class; C has no class, so no such requirement exists. * Both accept an array of command-line args. * ** Java arrays know how long they are; C does not and thus the main function must have an additional parameter to know the length of the array. * The Java main method has a specific format; the C main function seems to be allowed to differ. * ** The C main function seems to be able to accept different numbers of arguments and have different return types (assuming the implementation allows it).
You can not overwrite a static method in Java,and 'main' is a static method.so,you can't overwrite the 'main'.
this in java is a keyword that refers to the current object of the class. It is also used in constructor overloading when you want to invoke one constructor from another within the same class.
No. It is a user defined function which the person who is creating the java class has to code by himself.

No. Java classes in web applications do not have Main Methods.
void to indicate the application is not returning the exit code to the outer calling process. The outer calling process is another program (not necessary written in java), the human invoke the program on OS level, a batch job/script, etc. It works just like any method in java. main() itself is a method.
becoz the main program doesnot return any value to the os.

The "main" function name is reserved and specifies the entry point of the application.

A method is a group of commands that are executed when you invoke, or call, the method. It is often called a "function", a "procedure", a "subroutine" in other languages; but in OOP environments, the name "method" is used instead.
