inheritance and composition in java code example
Example 1: Inheritance in java
class A
{
public void display()
{
System.out.println("class A display method");
}
}
interface B
{
public void print();
}
interface C
{
public void print();
}
public class HybridInheritanceDemo extends A implements B, C
{
public void print()
{
System.out.println("implementing print method");
}
public void show()
{
System.out.println("show method of class HybridInheritanceDemo");
}
public static void main(String[] args)
{
HybridInheritanceDemo obj = new HybridInheritanceDemo();
obj.show();
obj.print();
}
}
Example 2: inheritance in java
it is used to define relationship between two class,
which a child class occurs all the properties and
behaviours of a parent class.
Provides code reusability.
Ex: in my framework I have a TestBase
class which I store
all my reusable code and methods.
My test execution classes and
elements classes will extend the
TestBase in order to reuse the code.
