program for method overloading in java
class Calculate
{
void sum (int a, int b)
{
System.out.println("sum is"+(a+b)) ;
}
void sum (float a, float b)
{
System.out.println("sum is"+(a+b));
}
Public static void main (String[] args)
{
Calculate cal = new Calculate();
cal.sum (8,5); //sum(int a, int b) is method is called.
cal.sum (4.6f, 3.8f); //sum(float a, float b) is called.
}
}what is method overloading
Overloading mean same method name and different parameter,
it can happen in same class. it's a feature that
allows us to have more than one method with same name.
Example: sort method of Arrays class
Arrays.sort(int[] arr)
Arrays.sort(String[] arr)
....
Method overloading improves the reusability and readability.
and it's easy to remember
(one method name instead of remembering multiple method names)method overloading
//https://www.geeksforgeeks.org/overloading-in-java/
// Java program to demonstrate working of method
// overloading in Java.
public class Sum {
// Overloaded sum(). This sum takes two int parameters
public int sum(int x, int y)
{
return (x + y);
}
// Overloaded sum(). This sum takes three int parameters
public int sum(int x, int y, int z)
{
return (x + y + z);
}
// Overloaded sum(). This sum takes two double parameters
public double sum(double x, double y)
{
return (x + y);
}
// Driver code
public static void main(String args[])
{
Sum s = new Sum();
System.out.println(s.sum(10, 20));
System.out.println(s.sum(10, 20, 30));
System.out.println(s.sum(10.5, 20.5));
}
}method overloading in java
// Overloading by Changin the number of Arguments
class MethodOverloading {
private static void display(int a){
System.out.println("Arguments: " + a);
}
private static void display(int a, int b){
System.out.println("Arguments: " + a + " and " + b);
}
public static void main(String[] args) {
display(1);
display(1, 4);
}
}what is method overloading
Method overloading is providing
two separate methods in a class
with the same name but different arguments,
while the method return type
may or may not be different, which
allows us to reuse the same method name.
In my framework==
I use implicit wait in Selenium. Implicit wait
is an example of overloading. In Implicit wait
we use different time stamps such as SECONDS, MINUTES, HOURS etc.,
A class having multiple methods with
same name but different parameters
is called Method Overloadingwhat is method overloading and method overriding in Java?
Method overloading is providing two separate methods in a class with the same name but different arguments, while the method return type may or may not be different, which allows us to reuse the same method name.
Method overriding means defining a method in a child class that is already defined in the parent class with the same method signature, same name, arguments, and return typeCopyright © 2021 Codeinu
