package org.always.have.a.package;

/* --------------------------------------------------------- */
/** Always have some javadoc
class MyClassName
    // indent by 4 spaces.
    // use spaced to indent
    // The code must format OK with default tabsize of 8.

    private static final int ALL_CAPS_FOR_PUBLIC_CONSTANTS=1;

    // Field prefixed with __ for static of _ for normal fields.
    // This convention is no longer mandatory, but any given
    // class should either consistently use this style or not.
    private static String __staticField;
    private Object _privateField;

    // use getters and setters rather than public fields.
    public void setPrivateField(Object privateField)

    public Object getPrivateField()
        return _privateField;

    public void doSomething()
        throws SomeException
        Object local_variable = _privateField;
        if (local_variable==null)
             // do Something
