What is public static void main?
The main method is the starting point of any Java Programs execution. It is public - so that anyone can access it static - so that the JVM can call it without the necessity to create an object void - because the method doesnt actually return anything. It just kick-starts the program execution
What is constant and variable?

What is run-time object in qtp?
In QTP, a Run-Time Object (RO) is the state of an object QTP is using in some capacity during a test. The state of an RO is dependent on the activity of the test. An RO differs from a Test Object in that the properties of the object may change once the application is put under test. These changes are the reason for differentiating between Test time and Run time.

What is the use of static in public static void main?
The static keyword signifies that the method belongs to the class and not any of its objects. Hence, the JVM does not have to create an object of that class before beginning execution. Imagine how the JVM would create an object and invokes its method even before the class execution starts. That is why the main method is static and is the starting point of any java application.
What is the parameter specification for the public static void main method?
The Main method is the method in which execution to any java program begins. A main method declaration looks as follows: public static void main(String args[]){ } The method is public because it be accessible to the JVM to begin execution of the program. It is Static because it be available for execution without an object instance. you may know that you need an object instance to invoke any method. So you cannot begin execution of a class without its object if the main method was not static. It returns only a void because, once the main method execution is over, the program terminates. So there can be no data that can be returned by the Main method The last parameter is String args[]. This is used to signify that the user may opt to enter parameters to the java program at command line. We can use both String[] args or String args[]. The Java compiler would accept both forms.
