Method Setradius In Class Circle Cannot Be Applied To Given Types
Sep 7, 2014
I'm new to programming and I have an assignment due in java class. Here is the error code:
TestCircle.java:10: error: method setradius in class Circle cannot be applied to given types;
circle1 = inputCircle.setradius();
^
required: double
found: no arguments
reason: actual and formal argument lists differ in length
And here is my code:
import java.util.Scanner;
public class TestCircle
{
public static void main(String[] args)
{
double circle1;
double circle2;
double circle3;
Circle inputCircle = new Circle();
public class Circle { private double PI = 3.14159; private double radius; public Circle() { radius = 0.0;
[Code] ....
This is the error i am receiving:
Circle.java:78: error: method getRadius in class Circle cannot be applied to given types; System.out.println("A circle with a radius of " + circle.getRadius() + " will have an area of " + circle.getArea() + " , a diameter of " + circle.getDiameter() + " and a circumference of " + circle.getCircumference()); ^ required: double found: no arguments reason: actual and formal argument lists differ in length 1 error
import java.util.*;public class DebugSix { public static void main(String[] args) {
ArrayList<String>products = new ArrayList(); products.add("shampoo"); products.add("moisturizer"); products.add("conditioner"); Collections.sort(products);
[Code] ....
I am using netbeans and getting errors for display(); and size(); it is telling me the errors are :
for the display error, "method display in class DebugSix cannot be applied to given types; display();" and for the size() is : "cannot find symbol System.out.println(" The size of the list is " + size());"

I'm getting an error on line 51 and don't know what it means?

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++) {
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;
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;

Is this because I'm using JRE7? I can't find any documentation that indicates the repaint() method has changed since Java 5.
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;
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.
Trying to find a way to use primitive data types to overload sound()method. I can't seem to warp my head around using an int or a double to overload the method. And if I did, how do you call them in the main afterwards?
I am trying to remove the duplicate elements from ArrayList using .contains() if elements are primitive datatype it works but user-defined datatype does not work.
public class UserBean { String name; String address; public String getName() { return name;
I want to know is there any way we can call parent class method using child class object without using super keyword in class B in the following program like we can do in c++ by using scoop resolution operator
class A{ public void hello(){ System.out.println("hello"); } } class B extends A{ public void hello(){ //super.hello(); System.out.println("hello1");
I am just trying to test this array, for a locker combination program that involves classes...but the array is printing out the whacky numbers for the location. When I try to call the method in the main, it does not work. How do I call a method that exist within a class into the main method?
public class locker { public static void main(String[] args) { CombinationLock();
I am currently working on a dice game. I have a private method called rollDice and it performs the action of rolling two dice. For my project, I need to create another method called playerRolls and I am supposed to invoke the rollDice method in the playerRolls method and perform actions based off of that. My question right now is how do I invoke a method into another method of the same class?
i am having a problem while calling a method..i am having a class
Java Code:
public class MySer implements Runnable { public void getMessage(String msg) { ..., }.., } mh_sh_highlight_all('java'); i use the above class in another 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.
