Define a package named "MyPack" and create class "person" inside this package. Person class has two properties ID and name which are private. You have to create another package "Pack" where you have a class Employee which want to use the person two properties ID and name. Will the "pack" package can call them?
Write the program and explain.
package MyPack;
public class person {
private String ID = "201-15-3292";
private String name = "MD. Alif Sheakh";
}
package Pack;
import MyPack.*;
public class Employee {
public static void main(String[] args) {
person myObj = new person();
System.out.println("Name: " + myObj.name);
System.out.println("ID: " + myObj.ID);
}
}
We can't call it another package, mainly because the properties are private. However, private properties can be called in their own package
package MyPack;
public class person {
private String ID = "201-15-3404";
private String my_name = "Shazzad Shawon;
}
package Pack;
import MyPack.*;
public class Employee {
public static void main(String[] args) {
person MyObj = new person();
System.out.println("Name: " + MyObj.my_name);
System.out.println("ID: " + MyObj.ID);
}
}
The "Pack" package can't call them(MyPack.person). Because the properties of the person in the "MyPack" Package are in a private firm which is why we cannot call it in the "Pack" package, but if we make the personal properties public then we can call it on the "Pack" package.
so, private properties can be called in their own package.
package MyPack;
public class person {
private String ID;
private String Name;
public void varify(String ID, String Name) {
this.ID = ID;
this.Name = Name;
}
public String getID()
{
return ID;
}
public void setID(String ID) {
this.ID= ID;
}
public String getName()
{
return Name;
}
public void setName(String Name) {
this.Name = Name;
}
}
package Pack;
import MyPack.*;
import java.util.Scanner;
public class Employee {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
System.out.print("Enter the ID : ");
String id = s.nextLine();
System.out.print("Enter the Name : ");
String name = s.nextLine();
person p= new person();
p.varify(id, name);
System.out.println("\nThe name is : "+p.getName());
System.out.println("The ID is : "+p.getID());
}
}
package MyPack;
public class person
{
private String ID = "201-15-3078";
private String Name = "Md. Uzzal Hossain Hridoy";
}
package Pack;
import MyPack.*;
public class employee
{
public static void main(String[] args)
{
person obj = new person();
System.out.println("Name: " + obj.Name);
System.out.println("ID: " + obj.ID);
}
}
