Need of Variable length arguments in java || Understand with examples || varargs

Hi, this video covers variable length argument in java.We are going to discover the reason why we need vararg in java.We will start this concept creating a real-time scenario and understanding the problem then we get into the coding.

variable argument lists in java //

Java var-args can be written inside a method argument which can accept a group of elements.This helps us in situations like when we are not sure how many arguments, we should take in a method.

If we take variable length argument as the argument inside a method then the method can handle any number of arguments passed into it.

So we can think, var-args in java is just similar to a one-dimensional array but the basic differences taking an array as a parameter and a var-args as a parameter is :

if we need to pass a method which accepts an array as an argument, then we have to pass an array object inside the method argument while calling the method.( this is the only way to call an array args type method)

we can’t pass elements directly to a method which takes an array as an argument.

But if we use a method which takes, var-args as an argument, then the advantages that we will get is :

we can pass an array object to this method and also we can pass a bunch of elements directly to this method to execute it.

please follow this tutorial for example.

I saw your subscribers climbing and dismissed it as maybe they just think you are cute or something, after all there are plenty of channels doing good tutorials. I see why people are liking you tho. You know what you are talking about, and don't seem to get lost at the keyboard interrupting flow. You have attractive, pleasant looking graphics that are easy to read and don't overly distract the viewer. Your delivery is very easy to understand, audibly. You don't sound bored and sleepy, nor do you sound angry or like you drank way too many coffees. Pleasant, highly competent instruction on important topics. Another new subscriber.

THANKS
public class A9UsingVarargs {


public static void main(String[] args){

A9UsingVarargs obj = new A9UsingVarargs();
int a[] = {10, 20, 30, 40, 50};

obj.add(a);

}


void add(int...numbers){ // accepts an arry of numbers
int result =0;
System.out.println("Inside the add method");
for(int eachX: numbers){
result = result+ eachX ;

}
System.out.println(result);
}


}
