Question

(Using Encapsulation)

Create a class named 'Student' with 2 instance variables (both set as private)

 The 2 variables are: String variable 'name' and integer variable 'roll_no'.

 Create a get and set Method for each variable.

Also create a class with Main Method, where you will:

 Create an object of the class Student

 Allow the user to enter a value for the name and roll_no and accept the values by using

the set Method of each variable

 Display the content of the object by using the get Method of each variable

Answer 1

import java.util.Scanner;


class Student {
	private String name;
	private int roll_no;


	/**
	 * @return the name
	 */
	public String getName() {
		return name;
	}


	/**
	 * @param name the name to set
	 */
	public void setName(String name) {
		this.name = name;
	}


	/**
	 * @return the roll_no
	 */
	public int getRoll_no() {
		return roll_no;
	}


	/**
	 * @param roll_no the roll_no to set
	 */
	public void setRoll_no(int roll_no) {
		this.roll_no = roll_no;
	}
}


public class App {


	/**
	 * The start point of the program
	 * 
	 * @param args
	 */
	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Enter the student's name: ");
		String name = keyBoard.nextLine();
		System.out.print("Enter the student's roll no: ");
		int roll_no = keyBoard.nextInt();


		Student student = new Student();
		student.setName(name);
		student.setRoll_no(roll_no);


		System.out.println("\nThe student's name: " + student.getName());
		System.out.println("The student's roll no: " + student.getRoll_no());
		keyBoard.close();


	}
