You could try reading the javadoc entry for HashMap and ArrayList

Go into your Java installation folder and explore it until you find a file called src.zip. Unzip that and explore it until you find the HashMap and ArrayList classes (remembering the folders reflect the package structure). You can open the code with a text editor and read it and see for yourself.
