Explain is-a relation ship in java

Question

Answer 1

It's helpful to also contrast the "IS A" relationship of inheritance with another OOP concept known as composition which applies the "HAS A" relationship.

Answer 2

You express IS-A relationship in Java through the keywords extends and implements.

//Condsider the following code sinppets
public class A {....}
public class B extends A{....}

Here B inherits A thus we say that "B IS-A A"
