         class Course { 
             String courseName; 
             Course() { 
                 Course c = new Course(); 
                 c.courseName = "Oracle"; 
             } 
         } 
         class Main { 
             public static void main(String args[]) { 
                 Course c = new Course(); 
                 c.courseName = "Java"; 
                 System.out.println(c.courseName); 
             }
