Can you have a method in Java with varying number of arguments?

Java 8Object Oriented ProgrammingProgramming

Yes, we can write a method using variable arguments once you use variable arguments as a parameter method while calling you can pass as many numbers of arguments to this method (variable number of arguments) or, you can simply call this method without passing any arguments.

Example

Live Demo

public class Sample{
   void demoMethod(String... args) {
      for (String arg : args) {
         System.out.println(arg);
      }
   }
   public static void main(String args[] ){
      new Sample().demoMethod("ram", "rahim", "robert");
      new Sample().demoMethod("krishna", "kasyap");
      new Sample().demoMethod();
   }
}

Output

ram
rahim
robert
krishna
kasyap
raja
