Java Methods parameter lists

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.
    Variable-Length parameter example:
    public class VariableLength {
    void printObjects( Object ... list ) {
       // list is an Object [] (array)
       for( Object o : list )
           System.out.println( o );
    }
      public static void main(String args[]) {
         String[] priceCat = {"Low", "Middle", "High"};
         new VariableLength().printObjects(priceCat);
      }
    }
    The result of this is:
    Low
    Middle
    High
