119. Class implementing multiple Interfaces

A class can implement more than one interfaces by separating the interfaces with commas ' , '  as shown below:

class ClassName  implements Interface1, Interface2, Interface3
{

     //Body of the class

}

Lets implement this on Eclipse IDE:

1. Create Interface 'Interface1'  as shown below:

2. Create Interface 'Interface2' as shown below:

3. Create Interface 'Interface3' as shown below:

4. Create Interface 'Interface4' as shown below:

5. Create a class which implements all the above interfaces as shown below:

6. Create a class 'MultipleInterfaceDemo' which creates an object for 'ClassOne' class to access all the methods in it as shown below:

7. Save and Run the 'MultipleInterfaceDemo' class
8. Observe that the output is displayed in the console as shown below:
