Question

This program makes use of the GraphicsFrame class and the Drawable interface. Your missions is to create the class Airplane. Each Airplane object should store the following information (fields): manufacturer modelNumber maximumSpeed // in knots maximumFuel // in gallons grossWeight // in lbs emptyWeight Each airplane object should have the following behaviors (methods): public float usefulLoad() // this is the grossWeight - emptyWeight public float usefulLoadWithFuel( in gallons ) // this is the useful load - gallons x 6. The programmer user will pass in the number of gallons on board. public void draw( Graphics g ) // this method will make a line drawing of an airplane. You don't have to get fancy. Do use drawString() to display the Airplanes information. You will also need a constructor to initialize the fields. You will need to put the GraphicsFrame, Drawable, Airplane, and the test driver all in one folder. The files need to 'see' each other. You can just add on the the test driver for the example. Some starter code for the Airplane class: public class Airplane implements Drawable { // fields // constructor or constructors // general methods }

Explanation / Answer

recently i did some work on drawable...may be it helps you..

public class Square extends Drawable
{
    private final Paint mPaint;
    private final RectF mRect;

    public Square()
    {
        mPaint = new Paint();
        mRect = new RectF();
    }

    @Override
    public void draw(Canvas canvas)
    {
        // Set the correct values in the Paint
        mPaint.setARGB(255, 255, 0, 0);
        mPaint.setStrokeWidth(2);
        mPaint.setStyle(Style.FILL);

        // Adjust the rect
        mRect.left = 15.0f;
        mRect.top = 50.0f;
        mRect.right = 55.0f;
        mRect.bottom = 75.0f;

        // Draw it
        canvas.drawRoundRect(mRect, 0.5f, 0.5f, mPaint);
    }

    @Override
    public int getOpacity()
    {
        return PixelFormat.OPAQUE;
    }

    @Override
    public void setAlpha(int arg0)
    {
    }

    @Override
    public void setColorFilter(ColorFilter arg0)
    {
    }
}
