Task:
There are some figures of the following types: square, rectangle, right triangle, circle, isosceles trapezoid.
You need to create corresponding classes for them(Square
, Rectangle
, RightTriangle
, Circle
, IsoscelesTrapezoid
)
All figures have
- state - all figures have
color
, but each figure type can also have one or several unique properties (radius
for circle,firstLeg
andsecondLeg
for right triangle, and so on). - behavior - we can obtain the area of any figure and are able to draw it. To 'draw' means to print out all information about a figure using
System.out.println()
(you shouldn't override the toString() method for this).
Think where you should declare these fields and methods: top-level class/interface / bottom-level classes.
In the main()
method we need to create an array of figures (the size of the array can be 3 or 6, it doesn't matter).
The first half of figures in this array should be generated with random parameters.
For this purpose create two more classes:
ColorSupplier
withpublic String getRandomColor()
method - for generating random color,- and
FigureSupplier
with thepublic Figure getRandomFigure()
method - for generating figures with random properties.
The other half of the figures should have the same, default parameters.
For this purpose create a new method in the FigureSupplier
class:
public Figure getDefaultFigure()
- this method should always return a white circle with a radius of 10.
After generating the array, we need to display the entire list of objects that we have, for example:
Figure: square, area: 25.0 sq. units, side: 5 units, color: blue
Figure: triangle, area: 12.5 sq. units, firstLeg: 7 units, secondLeg: 5 units, color: yellow
