In Db class we have two attributes/instance variables with the private visibility. meaning they
cannot be accessed outside of the class. Instance variables: name: data - type: String
Visibility/Access modifier: private name: yint - type: int Visibility/Access modifier: private Methods:
insertData - lets you set the values to above encapsulated instance variables. getData - getter
method for private data getYint - getter method for private yint setData -
for example:
Db db = new Db();
db.insertData("aaa",123);
System.out.println(db.getData());//aaa
System.out.println(db.getYint());//123
db.setData("zzz");
db.setYint(200);
System.out.println(db.getData());//zzz
System.out.println(db.getYint());//200
How to Submit?
//Create and use the object of Db class
// Use scanner class to provide data parameters
Example:
Input : Insert Data:
zzz
123
Output: zzz
123
Set Data:
123
zzz
write code in:
import java.util.*;
class Main {
public static void main(String[] args) {
//Your Code Here
System.out.println(db.getYint());
System.out.println(db.getData());
scanner.close();
}
}
write code in:
class Db {
//Your Code Here
