 import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.ButtonGroup;
import javax.swing.JApplet;
import javax.swing.JCheckBox;
import javax.swing.JList;

public class j_01_FLOW_06 extends JApplet implements ActionListener

    JCheckBox f = new JCheckBox("f");
    JCheckBox g = new JCheckBox("g");
    JCheckBox cb_computer = new JCheckBox("Computer");

    String s_value[]={"white sox","red sox","mets","cordianls","blue jays"};
    JList l_list = new JList(s_value);

    Container c;
    FlowLayout flow = new FlowLayout();

    public void init()
        c = getContentPane();



    public void actionPerformed(ActionEvent e) 
        boolean selected = cb_ikhlas.isSelected();

        if(selected == true) //if check box is selected
            Object[] string = f.getSelectedObjects();

Swing was built on top of AWT, so there are a few AWT classes that you still use with swing because there was no need to replace them. Container is one that you still use; your code is OK.
