A good answer might be:

Using the Panel's add() method.

Use the add() method to place components inside containers, including Panels. When adding a component to a Panel, you need to use the Panel's add() method, which you do using dot notation:

thePanel.add( componentForPanel );

Panels will automatically use the FlowLayout layout manager with the components placed inside of them. Here is part of the fat calculator:

public class percentFat extends Frame implements ActionListener { Label title = new Label("Percent of Calories from Fat"); Label fatLabel = new Label("Enter grams of fat: "); Label calLabel = new Label("Enter total calories: "); Label perLabel = new Label("Percent calories from fat: "); TextField inFat = new TextField( 7 ); TextField inCal = new TextField( 7 ); TextField outPer = new TextField( 7 ); Button doit = new Button("Do It!"); Panel fatPanel = new Panel(); // fat input components Panel calPanel = new Panel(); // calorie input components Panel perPanel = new Panel(); // percent fat output components percentFat() // constructor { setTitle("Calories from Fat"); setLayout( new FlowLayout() ); // choose the layout manager for the Frame // add components to the Panels fatPanel.add( ) ; fatPanel.add( ); calPanel.add( ); calPanel.add( ); perPanel.add( ); perPanel.add( ); . . . . . . . . }

Decide what two components should be added to each Panel. The order in which they are added does matter. Click on the button to see if you are right.

QUESTION 5:

Now what must be done with the title, the Panels, and the doit Button?
