No. void is not a data type.
It is mandatory for all java methods to return something and if it is not going to return anything, we have to mark the method with a "void" return type to let the JVM know that it must not expect anything from the method.

What is psvm in java?
public static void main
Why should the java main method has the return type as void?
A void method is one that returns no value. The Java main() method is the first method to be called, therefore it doesn't need to return a value to another Java method, therefore it is declared as void. If something needs to be returned to the operating system, this is done differently, not by "returning a value" in the sense of Java.
Why using the name main for main method in java?
If you run an java file(as an .class or .jar file) there's always 1 method being called: The main(String[] args) method.The method is only called once.Example of an main method:public static void main(String args[]) throws IOException {LoggingBootstrap.bootstrap();gui = new GUI();}In this case it only bootstraps the logger and uses the constuctor method of GUI(the graphical user interface of the program)
Can return statement be in a void method in java?
the main method in java is the client code therefore doesn't return any values Unlike languages like C/C++, the user doesn't specify an error return code by returning from the main method. Instead they should use System.exit(code) to do this. If the Java main method returns, the default code of zero is returned.
Can you have two mains in java?
Yes... We can have more than one main in JAVA... Just make the only one main method as public and other as default access specifier.... public class Test { public static void main(String args[]) { } } class Test1 { public static void main(String args[]) { } } class Test2 { public static void main(String args[]) { } } Just copy the above code and try.... Have fun in learning... :-) :) :-)

Why void main is used except int main in java?
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.
