Varargs 사용하기

class VarTest{
 public void sayEcho(String ... names){
  for (String name : names){
   System.out.println(name);
  }
  System.out.println();
 }
 public void sayEcho(String name){
  System.out.println("name : " + name); //오버로딩
 }
}

public class Ex05_7{
 public static void main(String[] args){
  VarTest var = new VarTest();
  var.sayEcho("홍길동");
  var.sayEcho("이순신", "홍길동");
  var.sayEcho("강감찬", "홍길동", "이순신");
 }
