Answer 1

Answer:

Note : If we create method using static keyword then there is no need to create object of class to call that method.

File: City.java

public class City
{
   static void dispMessage()//method using static
   {
       System.out.println("City Info Version 1.0");//Printing message to console
   }
   public static void main (String args[])
   {
       dispMessage();//calling method without creating object of class
   }
}

Screen:

1 2 public class City { static void dispMessage() //method using static System.out.println("City Info Version 1.0");// Printing message to console public static void main (String args[]) dispMessage();//calling method without creating object of class 11 } C:\Program Files\Java\jdk1.8.0_191\bin>javac City.java C:\Program Files\Java\jdk1.8.@_191\bin>java City City Info Version 1.0 C:\Program Files\Java\jdk1.8._191\bin>.
