What is the output of the following code? public class inherit { abstract class speaker { abstract public void speak(); } class cat extends speaker { public void speak() { system. out. println("woof! "); } } class dog extends speaker { public void speak() { system. out. println("meow! "); } } inherit() { speaker d = new dog(); speaker c = new cat(); d. speak(); c. speak(); } public static void main(string[] args) { new inherit(); } }

The answer is "Meow! Woof!"

Explanation:

The description of the java program can be given as:

In the java program, a class Inherit is defined inside a class an abstract class that is "speak" is defined that contains an abstract method that is "speak".In the next step we define two classes that are "Cat and Dog" both classes inherit the abstract class and its method. Cat class use the abstract method speaker and write a message that is "Woof!" and the Dog class use this method and write a message that is "Meow!".In the next step, create an Inherit class constructor and inside this constructor, we create an instance and call both classes.In the main method, we create an Inherit class instance.
