Multiple Interfaces Example
This program demonstrates multiple inheritance using interfaces.
Problem Statement
Write a Java program where class PrinterScanner implements both Printer and Scanner interfaces.
Source Code
| 1 | interface Printer { |
| 2 | void print(); |
| 3 | } |
| 4 | interface Scanner { |
| 5 | void scan(); |
| 6 | } |
| 7 | class PrinterScanner implements Printer,Scanner { |
| 8 | public void print(){ System.out.println("Printing document"); } |
| 9 | public void scan(){ System.out.println("Scanning document"); } |
| 10 | } |
| 11 | public class MultipleInterfaces { |
| 12 | public static void main(String[] args) { |
| 13 | System.out.println("Eduinq Multiple Interfaces"); |
| 14 | PrinterScanner ps=new PrinterScanner(); |
| 15 | ps.print(); ps.scan(); |
| 16 | } |
| 17 | } |
Program Output
Eduinq Multiple Interfaces Printing document Scanning document
Explanation
Java supports multiple inheritance via interfaces. - Class implements multiple interfaces and provides all methods. - This allows combining behaviors from different sources. Conclusion: Shows how to achieve multiple inheritance using interfaces.
