SINGLE INHERITANCE :
The below diagram represents the single inheritance in java where Class B extends only one class Class A. Here Class B will be the Sub class and Class A will be one and only Super class.
class Shape
{
int length;
int breadth;
}
public class Rectangle extends Shape
{
int area;
public void calcualteArea()
{
area = length*breadth;
}
public static void main(String args[])
{
Rectangle r = new Rectangle();
//Assigning values to Shape class attributes
r.length = 10;
r.breadth = 20;
//Calculate the area
r.calcualteArea();
System.out.println("The Area of rectangle of length \""
+r.length+"\" and breadth \""+r.breadth+"\" is \""+r.area+"\"");
}
}
