Question

EDIT (CODE IN TEXT):

public static void wain(String0 args) {
Shape tri1 = new Triangle();
Shape tri2 = new Triangle();
Shape cir1 = new Circle();

Drawing drawing1 = new Drawing();
Drawing drawing2 = new Drawing();
Drawing drawing3 = new Drawing();

drawing3.add(tri2);

drawingLadd(tri1);
drawingZ.add(drawing3);

drawing1.add(cir1);
drawing1.add(drawing2);

drawing1.setColour("Green");
drawing2.setColour('White");
drawing3.setColour("Gold");

drawing1.print();
}

(b) The Java code below illustrates how a Drawing object may be composed of another Drawing object and Shape objects such as a Circle. Using an appropriate Design remaining code that would be required to make this code run to produce the output shown below. (c) Refactor your code so that the setColour method will throw an exception if it receives a parameter value other than Green", "white" or "Gold". The method should not be case-sensitive either, so "green", "white" or gold" should be acceptable. Show how you handle the exception. public static void main(String[] args) { Shape tri1 = new Triangle(): Shape tri2 = new Triangle(): Shape cir1 new Circle(): Drawing drawing1 = new Drawing(): Drawing drawing2 = new Drawing(): Drawing drawing3 = new Drawing(): drawing3.add(tri2): drawing2.add(tri): drawing2.add(drawing3): drawing1.add(cir1): drawing1.add(drawing2): drawing1.setColour("Green"): drawing2.setColour("White"): drawing3.setColour("Gold"): drawing1.print(): } Output Drawing Circle with color Green Drawing Triangle with color White Drawing Triangle with color Gold

Explanation / Answer

Answer for this Question:

See the below method to add try catch block in setColour method, It will handle the excepton.

public void setColour(String color)

{

try

{

if(color.equals("Green") || color.equals("green") || color.equals("White") || color.equals("white") || color.equals("Gold") ||color.equals("gold")) throw "Error"

// Try block to handle code that may cause exception

} catch (String e) {

// This block is to catch divide-by-zero error

System.out.println("Error: Set Color is not accept "+e);

}

System.out.println("I'm out of try-catch block in Java.");

}
