Question
A labeled point has x- and y-coordinates and a string label. Create a Java class LabeledPoint with a constructor LabeledPoint(int x, int y, String label)
A labeled point has x- and y-coordinates and a string label. Create a Java class LabeledPoint with a constructor LabeledPoint(int x, int y, String label) and a toString method that displays x, y, and the label. The Java class LabeledPoint must extend the Java AWT class (java.awt.Point). The toString method of LabeledPoint should invoke the toString method of the Point class. Also, the constructor of LabeledPoint should invoke a constructor from the Point class. Create a tester class (LabeledPointTester) with a main method that tests the toString method of LabeledPoint. LabeledPointTester must have at least 3 test cases with input and expected output.
The java.awt.Rectangle class of the standard Java library does not supply methods for computing the area and the perimeter of a rectangle. Create a subclass BetterRectangle of the Rectangle class that has getPerimeter and getArea methods. Do not add any instance variables to the BetterRectangle class. In its constructor, call the setLocation and setSize methods of the Rectangle class. Create a tester class (BetterRectangleTester) with a main method that tests the methods of BetterRectangle. BetterRectangleTester must have at least 3 test cases with input and expected output.
