Var-Arguments

Var-Arguments:

• It is also introduce in jdk-5.
• Allow to pass 0 to infinite number of arguments using single parameter in a method.
• Reduce maintenance problem, before this we have to mention that how many arguments have to pass in a method as argument during compilation but now it will automatically hold any number of arguments .
• It is helpful when we don't how many arguments have to pass.

Syntax: 

   return_type method_name(data_type ... variable_name){

//statements

}

Example:

class DemoVaragrs

{

          public static void main(String st[]){

                   DemoVarargs dv=new DemoVarargs();

                   dv.show(12,23);

                   dv.show(1,2,3,4);

          dv.show(23,45,67,89,90);

          }

          void show(int ...a)

          {

                   for(int aa:a)

               System.out.println(aa);

          }

}
