Java Code:
public class VarArgs { 
  // vaTest() now uses a vararg. 
  static void vaTest(int ... v) { 
    System.out.print("Number of args: " + v.length + " Contents: "); 
    for(int x : v) 
      System.out.print(x + " "); 
    System.out.println(); 
  } 
  public static void main(String args[]){ 
    // Notice how vaTest() can be called with a 
    // variable number of arguments.     vaTest(10);      // 1 arg 
    vaTest(1, 2, 3); // 3 args 
    vaTest();        // no args 
  }
