Java Methods variable-length parameter lists

  • When you specify a variable-length parameter for a method, you must use ... (Three dots) after the parameter type and then the variable name.

           System.out.println( o );
      public static void main(String args[]) {

         new VariableLength().printObjects(priceCat);
