 class college {
    String name="IIT";
	  
    college(){
     System.out.println("Parent class constructor");
	 }
	  
    void display(){
	  System.out.println(name);
	}
}
	  
    

student.java

class student extends college{
    String name="Sam";
		
	student(){
	 System.out.println("Child class constructor");
	}
		
	void show(){
	  super.display();
	  System.out.println(name);
	}
		  
    public static void main(String args[]){
     student s=new student();
	 s.show();
  }
}
