Java code to illustrate package and Interface. Here screenshot shows two packages -First and second. Package First contains Interface myinterface.(myinterface.java) Package second contains Class Banking(Banking.java) myinterface.class package First; public interface myinterface { public void createAccount(int v); public void displayBalance(); public void displayRecords(); public void updateBalance(int val); } Banking.java package second; import java.util.Scanner; import First.myinterface; public class Banking implements myinterface{ static int no; int account_no; int balance; String Cust_name; void getdata() { System.out.println("Enter Balance"); Scanner sc=new Scanner(System.in); balance=sc.nextInt(); System.out.println("Enter Customer Name"); Cust_name=sc.next(); } public void createAccount(int val) { account_no=val; getdata(); } int getAccno() { return account_no; } public void displayB

In this assignment we are illustrating how to import class in other package. In java , classes and interfaces can be grouped in packages. Right click newly created java project and you will see option new-> package as shown below. create java project :packageDemo Right click newly created project ( packageDemo ) select new-> select package Click on package. (enter package name eg: Package name :First) click on finish. Right click the package created (First). Add new class. Following image shows two packages created First (with class in it class1.java) and Second (with class in it class2.java). Add following code in Class1.java package first; public class class1 { int num; public void getdata(int id) { num=id; System.out.println("getdata() of Class1 from package first invoked"); } public void display() { System.out.println(num); } } create other package (
