You can look in the ArrayList.java source code itself. It defined in the default constructor as follow:

Code:

   /**
     * Constructs an empty list with an initial capacity of ten.
     */
    public ArrayList() {
	this(10);
    }

You can find the source code in your JDK folder, in my PC it is C:\Program Files\Java\jdk1.6.0_03\src.zip
