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
