Polymorphism is one of the oops pillars in java. It has two types. They are,
1.Compile time polymorphism (or) Method Overloading
2.Run time polymorphism (or) Method Overriding
1.Method Overloading:
- Method Overloading allows multiple methods with the same name but different number and types of arguments within a class.
- Method Overloading is very important to naming convertion.
Example:
public class SuperMarket
{
static String shopname = "Kanchi Super Market";
String product_name;
int price;
public static void main(String[] args)
{
SuperMarket product = new SuperMarket();
product.buy(10);
product.buy(5,50);
product.buy(10.5f, 10.3f);
product.buy(100.5d);
}
void buy(int no)
{
System.out.println("buy one args" +"=" +no);
}
void buy(int no1, int no2)
{
System.out.println("buy two args" +"=" +no1+" "+no2);
}
void buy(float no3, float no5)
{
System.out.println("buy two float args" +"=" +no3+" "+no5);
}
void buy(double no4)
{
System.out.println("buy one double args"+"=" +no4);
}
}
Output:
buy one args=10
buy two args=5 50
buy two float args=10.5 10.3
buy one double args=100.5
