Write a Java program to display student details using inheritance

import java.io.*;
class Student_Details {
    String name;
    int roll;
	String cname;
    String uname;
    InputStreamReader in = new InputStreamReader(System.in);
    BufferedReader br = new BufferedReader(in);
void input() throws IOException {
		System.out.print("Enter Student Name: ");
        name = br.readLine();
        System.out.print("Enter Roll Number: ");
        roll = Integer.parseInt(br.readLine());
		System.out.print("Enter College Name: ");
        cname = br.readLine();
        System.out.print("Enter University Name: ");
        uname = br.readLine();
    }
}
class Main extends Student_Details {
void display() {
	        System.out.print("\n**** Student Details ****\n" );
		System.out.print("\nStudent Name: " + name);	
                System.out.print("\nRoll Number: " + roll);
		System.out.print("\nCollege Name: " + cname);
                System.out.print("\nUniversity Name: " + uname);
    }
public static void main(String args[]) throws IOException {
        Main c = new Main();
        c.input();
        c.display();
    }
}

Output:
