Using inheritance , one class can acquire the properties of others. Consider the following Animal class: class Animal { void walk (){ System . out . println ( "I am walking" ); } } This class has only one method, walk . Next, we want to create a Bird class that also has a fly method. We do this using extends keyword: class Bird extends Animal { void fly () { System . out . println ( "I am flying" ); } } Finally, we can create a Bird object that can both fly and walk . public class Solution { public static void main ( String [] args ){ Bird bird = new Bird (); bird . walk (); bird . fly (); } } The above code will print: I am walking I am flying This means that a Bird object has all the properties that an Animal object has, as well as some additional unique properties. The code above is provided for you in your...
