Varargs
~~~~~~~~~~~~~~~~~~~~~
This can be handled in two ways. One using an overloaded method(one for each) and another put the arguments into an array, and then pass this array to the method. Both of them are potentially error-prone and require more code. The varargs feature offers a simpler, better option.

Few Points:
Vararg Methods can also be overloaded but overloading may lead to ambiguity.
Prior to JDK 5, variable length arguments could be handled into two ways: One was using overloading, the other was using an array argument.
There can be only one variable argument in a method.
Variable argument (varargs) must be the last argument.

Traditional Approach Example :
public void addition(int port, String hostName, float value, String enpointUrl, String protocol){
// Method body
}
// Varargs approch example :
public void addition(int port,float value, String ... args){

// Method body
}
