Java 在方法重载中使用变参

public class Main {
   static void vaTest(int ... no) {
      System.out.print(
         "vaTest(int ...): " + "Number of args: " + no.length +" Contents: ");
      for(int n : no)System.out.print(n + " ");
      System.out.println();
   }

   static void vaTest(boolean ... bl) {
      System.out.print(
         "vaTest(boolean ...) " + "Number of args: " + bl.length + " Contents: ");
      for(boolean b : bl)System.out.print(b + " ");
      System.out.println();
   }

   static void vaTest(String msg, int ... no) {
      System.out.print(
         "vaTest(String, int ...): " + msg +"no. of arguments: "+ no.length +" Contents: ");
      for(int  n : no)
      System.out.print(n + " ");
      System.out.println();
   }

   public static void main(String args[]) {
      vaTest(1, 2, 3);
      vaTest("Testing: ", 10, 20);
      vaTest(true, false, false);
   }
