Which method is used to initialize the applets?
public void init(): is used to initialized the Applet. It is invoked only once. public void start(): is invoked after the init() method or browser is maximized.
What is parameter passing in applet?
We can get any information from the HTML file as a parameter. For this purpose, Applet class provides a method named getParameter().
What is the first method of an applet to be executed?
init():
init(): The init() method is the first method to execute when the applet is executed. Variable declaration and initialization operations are performed in this method.
Which are the common security restrictions in applets?
The common security restrictions of applet are as follows:
- Applets can’t load libraries or define native methods.
- An applet can’t ordinarily read or write files on the host that’s executing it.
- An applet can’t make network connections except to the host that it came from.
Who is responsible to manage the life cycle of an applet?
Applet life cycle is managed by Java Plug-in software. 13.
What is the life cycle of an applet?
An applet has four main steps in its lifecycle: An init() event initializes any variables or methods. A start() event runs the applet. A stop() event ends processing.
What is the difference between init () and start () method explain?
The init( ) method is the first method to be called. The init( ) method is called by the browser when the applet begins execution. This method is called only once during the run time of your applet. The start( ) method is executed after the init( ) method completes its execution.
What is an applet and its life cycle?
Applet life cycle defined as how the object created, started, stopped and destroyed during the entire execution of the application is said to applet life cycle. Applet life cycle has 5 methods init(), start(), stop(), aint() and destroy(). These methods are invoked by the browser to execute.
What is the sequence of major events in the life of an applet?
Which method is only called when the browser shuts down normally?
destroy −
destroy − This method is only called when the browser shuts down normally. Because applets are meant to live on an HTML page, you should not normally leave resources behind after a user leaves the page that contains the applet.
How many types of controls does AWT support?
AWT supports the following types of controls: Labels, push buttons, check boxes, check box groups, lists, scroll bars, text fields etc.
Which is correct order of applet life cycle?
A Java applet is a Java program which the web browser runs (depending on security permissions) and closes. An applet has four main steps in its lifecycle: An init() event initializes any variables or methods. A start() event runs the applet.
