Can a normal Class implement multiple interfaces?

I know that multiple inheritances between Interfaces is possible, e.g.:

public interface C extends A,B {...} //Where A, B and C are Interfaces

But is it possible to have a regular Class inherit from multiple Interfaces like this:

public class A implements C,D {...} //Where A is a Class and C and D are interfaces

Solution 1:

A Java class can only extend one parent class. Multiple inheritance (extends) is not allowed. Interfaces are not classes, however, and a class can implement more than one interface.

The parent interfaces are declared in a comma-separated list, after the implements keyword.

In conclusion, yes, it is possible to do:

public class A implements C,D {...}

Solution 2:

public class A implements C,D {...} valid

this is the way to implement multiple inheritence in java

Solution 3:

In a word - yes. Actually, many classes in the JDK implement multiple interfaces. E.g., ArrayList implements List, RandomAccess, Cloneable, and Serializable.
