Method Overloading with Different Parameter Counts and Varargs in Java

Write a Java program to demonstrate method overloading with different parameter counts and varargs

This Java program demonstrates method overloading in a class named Calculation, where multiple sum methods are defined to calculate the sum of different numbers. Let's break down the code:

The main method creates an instance of the Calculation class.
It then calls the sum methods with different numbers of arguments.
The Java compiler determines which overloaded method to call based on the number and type of arguments passed.
For each call to sum, the appropriate version of the method is invoked, and the result is returned.
The calculated sums are then printed to the console.

Source Code

class Calculation
{
	int sum(int a, int b)
	{
		return a + b;
	}
 
	int sum(int a, int b, int c)
	{
		return a + b + c;
	}
 
	int sum(int... numbers)
	{
		int total = 0;
		for (int num : numbers)
		{
			total += num;
		}
		return total;
	}
 
	public static void main(String[] args)
	{
		Calculation calc = new Calculation();
		System.out.println("Sum of Two Numbers : " + calc.sum(3, 5));
		System.out.println("Sum of Three Numbers : " + calc.sum(2, 4, 6));
		System.out.println("Sum of Four Numbers : " + calc.sum(10, 20, 30, 40, 50));
	}
}

Output

Sum of Two Numbers : 8
Sum of Three Numbers : 12
Sum of Four Numbers : 150
