Answer / dharma
main method signature must be like
public static void main(String args[])
if we declare as private then it compiles successfully
but at Runtime it says
"Main method not found in class"

Answer / chinmay
If main method declared as private then at compilation no problem but at run time it shows an error that main method should be public...
because we access the main() method out side from class if it is private then it cannot be accessible...
that's why we have to write public in main method signature...

Answer / sachin
JVM wants to execute the class its starting Execution from main Method means if JVM wants to execute main method if we declare main Method as private then its restriction the scope of main method if we declare Main Method as public then only jvm can applicable to access the main Method.
for e.g
class SE3
{
private static void main(String[] args)
{
System.out.prinln("Hello");
}
}
E:A_coreResearch_Programs>javac SE3.java
E:A_coreResearch_Programs>java SE3
Error: Main method not found in class SE3, please define the main method as
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application

Answer / thiru
The default signature should not be altered. If any changes, at run time "Class xxx does not have main method" exception will be thrown. But compilation will not give any exception.

Answer / pawan
vani, varsha is correct , the 'private main method' is as
good as any member method your class can have (note that
main is not a key word in java) , it can be only used inside
the class in which it is defined.
It is clearly mentioned in the specifications that the
executing class should contain a 'public static void method'
as a point of execution otherwise execution will fail
complaining ABOUT THE METHOD WHICH I MENTIONED ABOVE.
