Java provides the varargs feature to allow methods to accept a variable number of arguments. This is useful when the exact number of inputs is unknown.

Syntax:

returnType methodName(dataType... variableName) {
    // Method body
}

Code Example

​x
 
public class VarargsExample {    // Method that accepts variable number of arguments    public int sum(int... numbers) {        int total = 0;        for (int num : numbers) {            total += num;        }        return total;    }​    public static void main(String[] args) {        VarargsExample example = new VarargsExample();        System.out.println("Sum: " + example.sum(1, 2, 3, 4, 5));  // Sum of 5 numbers        System.out.println("Sum: " + example.sum(10, 20));        // Sum of 2 numbers    }}

Output

Sum: 15
Sum: 30
