init() method

[tilak kumar]

instead of init() mathod can we declare our own constructor

[Ernest Friedman-Hill]

You can define a contructor, yes, but there are things you can only do in init(). In particular, your "AppletStub" won't be set, yet, while the constructor is running, so you can't get applet parameters, load images from URLs, load sound files, etc. All of these things have to be deferred until init() time.
