Constructor In A Class Cannot Be Applied To Given Types

Feb 13, 2015

This code works

public class RedShapeDecorator extends ShapeDecorator {

public RedShapeDecorator(Shape decoratedShape) {
super(decoratedShape);
}

Below results in an error

public class RedShapeDecorator extends ShapeDecorator {

protected Shape decoratedShape;
public RedShapeDecorator(Shape decoratedShape) {

this. decoratedShape=decoratedShape;

}

So I am guessing that if you extend class, you should use super to pass objects?

Sort Strings In Alphabetical Order - Method Not Being Applied

Jan 21, 2014

I'm doing an exercise we're you're supposed to sort strings in alphabetical order, without importing anything , not using the Arrays.sort() method.

I think I got the method down partially right, or it is on the right track, but it is completely not being applied to my answer. All it prints out in the console is the actual String array twice, without sorting anything.

public class arrayofstrings {
public static void sort(String[] a) {
String temp= "";
int min;
int i= 0;
for (int j=0; j<a.length-1; j++) {

Method Should Return A Double That Is Diameter Of Circle

Jul 9, 2014

What's that diameter? Create a new method for the circle class called diameter. Add this method to the circle class described on page 15-1. It should return a double that is the diameter of the circle. No parameters are passed to this method.

In a tester class, test the performance of your new diameter method as follows:

(Your project should have two classes, Tester and Circle.)

here is what i have so far:

public class Circle
{
public Circle (double r)
{
radius = r;
}
public double area()
{
double a = Math.PI * radius * radius;

[Code] ....

Swing/AWT/SWT :: Repaint Method Is Automatically Erasing Old Circle?

Feb 19, 2014

This code is shown to eliminate "smearing":

public void paintComponent (Graphics g) {
g.setColor(Color.white);
g.fillRect(0,0,this.getWidth(), this.getHeight());
g.setColor(Color.green);
g.fillOval(x, y, 40, 40);
}

I had done all the previous code (in my own style) and found that the background rectangle was either being redrawn on its own, or there was something else removing the old circles from the screen. I then typed in the code from the previous page exactly as it was, to see if I had some change in syntax that would cause this, and it did the same thing.

Here's my code:

import javax.swing.*;
import java.awt.*;
public class SimpleAnimation {
int x, y;
private static final int HEIGHT = 600;
private static final int WIDTH = 600;

[Code] .....

Is this because I'm using JRE7? I can't find any documentation that indicates the repaint() method has changed since Java 5.

Write A Class Encapsulating Concept Of A Circle?

Mar 19, 2014

Prompt: Write a class encapsulating the concept of a circle, assuming a circle has the following attributes: a Point representing the center of the circle, and the radius of the circle, and integer.

Include a constructor, the accessors and mutators, and methods toString and equals.
Also include methods returning the perimeter ( 2 x 𝜋 x 𝑟 ) and area ( 𝜋 x 𝑟^2) of the circle.
Write a client (application) class to test all the methods in your class. I started out trying to thing how to do this and I mapped out a certain idea but do not know how to incorporate the point represent the center of the circle. I am not sure how to proceed further..

import java.awt.*;
public class Circle {
 public static void main(String[] args) {
 
final double PI = 3.14;
int x,y, radius = 4;
double area;
double perimeter;

LightController And Circle Class - Creating A Constructor

Jan 6, 2015

I have two classes LightController & Circle. I need to use the LightController class to do the following:

Creates an instance of Circle with a diameter of 50 and a colour of OUColour.GREEN and assigns this new circle to the instance variable light.

Sets the xPos of light to 122.
Sets the yPos of light to 162.

I am struggling to write the correct line of code to set the colour to green and set diameter to 50.

Code for the two classes below.

001
import ou.*;
002
import java.util.*;
003
/**
004
* Class LightController
005
* This class uses the Circle class, and the Shapes window

Create 4 Types Of Strings Under Same Method But Only Draw One At A Time

May 11, 2015

I am having trouble with methods. What I want to do is be able to create 4 types of strings under the same method, but only draw one of them at a time.

i.e

pipe2

pipe3

pipe4

I am having a lot of difficulty just printing one out after each time I press drain.

"drain"

pipe1

"drain"

pipe2 etc..

Creating Object Of Class And Calling Its Method In Different Class

In the process of creating a new class, I need to move my main method from the class SaveDate to the class DynamicTest. Below I have listed the code of both classes.The objective is to be able to run my program from the DynamicTest Class. I need understanding the process of moving my main method to a different class and creating an Object of a class and calling its method.
 
public class SaveData { 
  private static final Map<String, Object> myCachedTreeMap = new TreeMap<String, Object>();
   public static final List<String> getLines(final String resourceParam, final Charset charset) throws IOException{
  System.out.println("Please get: "+resourceParam);
  if (myCachedTreeMap.containsKey(resourceParam) ) {
  // Use the cached file, to prevent an additional read.
