import javax.swing.JFrame;

	}
	HelloWorldFrame() {

	}
}

public class SwingApplet extends JApplet {

JButton button;

public void init() {

// Force SwingApplet to come up in the System L&F
	String laf = UIManager.getSystemLookAndFeelClassName();
	try {
	    UIManager.setLookAndFeel(laf);
	    // If you want the Cross Platform L&F instead, comment out the above line and
	    // uncomment the following:
	    // UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
	} catch (UnsupportedLookAndFeelException exc) {
	    System.err.println("Warning: UnsupportedLookAndFeel: " + laf);
	} catch (Exception exc) {
	    System.err.println("Error loading " + laf + ": " + exc);
	}

getContentPane().setLayout(new FlowLayout());
        button = new JButton("Hello, I'm a Swing Button!");
        getContentPane().add(button);
    }

public void stop() {
        if (button != null) {
            getContentPane().remove(button);
            button = null;

i found error in this code,and i try to fix it with eclipse,but i can't,i didnt know why,can all of you help me fix this code?

and the error in public class SwingApplet,i try to fix it,but i am still can't fix it,altough i always try,help me please

Are you going to tell us what the problem with this code is, or are we supposed to guess?

without knowing how we will give you answers?

the error is in:

public class SwingApplet extends JApplet {

the error said: the public type SwingApplet must be defined in its own file

why this can be happen??

and i try to fix it with eclipse,but the code still error,altough i was try so many times,i still can't recognize where is the error from this code

please help me,thanks...

dhuha, you've been told about using code tags when you posted in this thread. I've added them for you, but you have to form a habit of reading responses to your posts and learning from them.

A file can contain only one public class, and a public class must be in a file with a name that matches the class name. Your SwingApplet code needs to be in a file named SwingApplet.java.

What are you trying to do with a JFrame class and a JApplet class together anyways?

i try to make swing applet,so i combine code from applet that i was learn before from my lecturer,and that code is JApplet class

and my code is Jframe,so i combined it, and hope can make a new code,that have a swing applet in it,is it right? or is it wrong?

so how come if i want to make an applet,but have a swing feature? i dunno

and about my habit,forgot to use code tags,i don't know to use it in this forum
where i can find codetags?and what button should i click? how i can make it,like you did?
explain it to me...

thanks,and sorry for my mistake,because i did'nt know to use code tags

A Java source file can have only one public class. You'll need to move that class to its own source file.

You need to create two java files:

SwingApplet.java
HelloWorldFrame.java

Since they don't appear to depend on each other from your code, compile and run separately.
