You can use a switch as part of the statement sequence of an outer switch This is called a nested switch Since a switch statement defines its own block, no conflicts arise between the case constants in the inner switch and those in the outer switch For example, the following fragment is perfectly valid:

1 Define form, field, label, jump menu 2 Explain why it is important to clearly label each field in a form 3 Summarize how a radio button is different from and similar to a check box

The values (in pixels) returned by the getWidth() and getHeight() methods can be used to draw an image at a given location that is proportional to the size of the canvas by using relative coordinates rather than exact coordinates on the canvas Let s say that the first element of the image you want drawn on the canvas is located in the center of the canvas The question you need to answer is what coordinate is the center of the canvas The answer depends on the canvas size, which depends on the small computing device that runs your MIDlet You work around this problem by letting your MIDlet calculate the center coordinate based on the return value of the getWidth() and getHeight() methods Here s what you need to do Assume the size of the canvas is 200 pixels wide (columns) and 200 pixels high (rows) The coordinate of the center of the canvas is 99, 99 (remember that coordinates are zero based), calculated as: x = getWidth()/2 y = getHeight()/2 Now assume the same MIDlet is running on a small computing device with a canvas size of 400 pixels wide by 400 pixels high The same calculation determines the center coordinate as 199, 199 Therefore, the MIDlet can use the calculation to determine the center coordinate of any size canvas, which means that the image will appear in the same canvas location when the MIDlet runs on any device Calculating a specific coordinate rather than specifying a fixed coordinate solves one problem facing a developer of a J2ME application Another problem is scaling an image to fit a canvas size that is device dependent If you knew the size of the canvas, you could plot each pixel that is required to draw an image The image will be symmetrical within the screen However, the symmetry is disrupted when the size of the canvas changes and the image size remains the same Let s say that you want to draw a line across the top of the canvas, but leave a one-pixel border around the line If the screen size is 200 pixels wide by 200 pixels high, the starting coordinate of the line is 1, 1 (the cell in the second column and second row beginning at the left corner) The ending coordinate is 1, 198 However, the line takes on a different appearance if the size of the canvas is 400 pixels by 400 pixels The line stops at the top center of the canvas because row 198 is halfway to the right of the canvas Therefore, you should write code that draws images proportional to the size of the canvas if being symmetrical within the canvas is critical to your application This means that you ll need to use relative coordinates to draw an image rather than specific coordinates by having your MIDlet calculate the specific coordinate of each element of your image For example, here is how to identify the coordinates for the line so that the length of the line is always proportional to the canvas size The starting coordinates are set as specific values because the line always begins one pixel from the left and top of the canvas Likewise, the x coordinate will always be the second row and can be fixed at row coordinate one However, the column coordinate used to specify the termination.
