My issue is that when I run the code if I enter anything but 1, 2, or 3 the code breaks. I have spent hours trying to find the error. here is my code
import java.util.Scanner;
public class Tester {
public static void main(String[] args) {
/**
* constructor
* pre: none
* post: inherit values of other classes
*/
Car Car = new Car(); //inherits the properties of the Car class
Truck Truck = new Truck(); //inherits the properties of the Truck class
We are making a Rational Number class. After that we must create client code to test it out. The instructions-
•Create 3 instances of RationalNumber. Remember every time you say “new” you are creating an instance. oOne of them should use the default constructor oOne of them should use the constructor with one parameter oOne of them should use the concstructor with two parameters. •Print out the int and double value of each Rational Number •Print out the sum (as a double) of all the numbers. •Print out the sum (as an int) of all the numbers.
My rational number class :
public class RationalNumber{ private int numerator; private int denominator; public RationalNumber() { numerator =1; denominator = 4;
This is what i have so far, I use BlueJay to write this:
import javax.swing.JOptionPane; public class payroll { String again = y; // private String name; private double rate; private double hours; static double gross; //gross pay
[code]....
my first problem is that it expects a ")" on this line :"if ((hours <=40)rate *1);"For the assignment itself these are the requirements:
-Create a class called payroll with private variables for rate hours and name
-Create static variables for gross pay, union dues, health coverage (hp in my case), FICA taxes, State taxes, Federal taxes, net pay, all must be initialized to 0
-default constructor that assigns default values
a function called calcPay that will do the following tasks and print it to a pay stub :
- function that checks the hours ( if hours are 40 or less pay rate, if over 40 pay 150% of the rate) - calculates gross pay before any deductions (using user inputted hours and rate) - deduct medical coverage and union dues from gross pay and call this adjusted gross pay (also this should have its own line on the paystub) - A function that deducts State, federal and fica taxes from adjusted gross - FICA - 7% for any income -Federal - 2% for $0-$150 / 6% for 150.01 - 300 / 14% for 300.01 - 600 / 18% for 600.01 - unlimited -State - 1% for 0-150/ 3% 150.01 - 300 / 5% 300.01 - 600/ 8% 600.01 - unlimited - amount after all deductions is the net pay ( show this amount on its own line) - Start a loop that asks each time if there are more employees (y/n) y should continue the program and n should end it -dialog boxes should be created to recieve values for name, hours and rate - if the rate is entered below $8 dollars a new box should pop up and ask for a higher value - When there are no more employees, print out a summary of quantities stored in static variable (also had a problem with this) - End
So I think i completed most of these objectives but am having trouble with the syntax and some of the objectives
So my only error in the entire code is on the 9th line of this code sample. It says "Syntax Error on token "new", @ expected" but @ does not belong there, as far as I can tell, since the error does not go away upon adding it.
public class Obstapacalypse implements KeyListener, ActionListener { private static final String EXIT_ON_CLOSE = null; private JFrame frame; private Player player = new Player(); private JPanel contentPane; private JButton btnStart;
I'm not sure why I'm getting these errors. They only begin to happen after the second if statement, and the subsequent if statements are formatted exactly the same.
The errors are marked by the comments in the code.
Java Code:
import java.util.*; import java.io.*; public class GazillionSongs { public static void main(String[] args) throws FileNotFoundException { System.out.println("Welcome to Java Song Collection!"); System.out .println("This program sorts and filters large databases of popular songs.");
My if else statement is not working...it keeps telling me that the else in the statement is a syntax error and that I should remove it. Whats wrong with it?
package Homework2; import java.util.Scanner; public class Homework2 { public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("Welcome to the Triangle Program.");
I have a problem with my code. It gives me the error I put as title:
backgroundA.setOnClickListener(new View.OnClickListener(){ public void onClick(View view){ if (j < 2){ int randomInt1 = random1.nextInt(Deck.length()); int drawableIDA = Deck.getResourceId(randomInt1, -1);
[Code] ....
This error is in the first line and I have also one in the last, where eclipse looking for a @ (O.o). Also I will insert the variable choice1.
final Button choice1 = (Button) findViewById(R.id.A);
I am currently working on modules of a java program but am having issues with this module . it gives this error code"syntax error on token '?', invalid primitive type".
this is a syntax error within Jasper reports in the printwhenexpression property.I can use the following expression successfully: new Boolean ($F{off_peak_free_minutes}. trim().equals("")==false) - this basically tells Jasper Reports to ignore the column unless it has a value.
Now I'm trying to do the same thing with ZERO but I can't get the syntax right. I've tried: new Boolean($F{off_peak_free_minutes} != 0) but the ZERO comes up with a red underline implying that this is illegal.I've also tried: new Boolean($F{friends_family_minutes}!=Double.valueOf(0)) but the ZERO comes up with the red underline.
I suspect I'm just not specifying the JAVA right. I believe that the $F{friends_family_minutes} variable is a DOUBLE - it prints as 0.00 on the report.
Multiple markers at this line - void is an invalid type for the variable loadDictionaryFromFile - Syntax error on token ")", ; expected - Syntax error on token "(", ; expected
Line 13 starts public void load....
Code:
import java.io.FileInputStream; import java.io.FileNotFoundException; import java.util.Scanner; public class PirateTranslator { public static void main(String[] args)
Netbeans do not detect any syntax errors, but I when I check the build it retuned areas they were a few; It's a simple program name 5 people, gade them then do final calulatoins it's called "grade tool.
heres the code
package gradingapplication; import java.util.Scanner; public class GradingApplication { public static double score(double score){ if(score >= 90){ System.out.println("A");
[code]...
~Problems~
1. It has no gui, I don't know java fx, is java groove used? awt is useful for creating spam bots in robot class, I know it's not very useful but it's so much fun.
I am trying to insert a record to a table in my database . I used the same syntax for 2 tables, one does work and the other does not work . I could not find any explanation for this error
"INSERT INTO CustomerRecord (Name, Number, Adress)" +" VALUES(?,?,?)"; //first table working well ps.setString(1,r.getCustomerName()); ps.setString(2,r.getCustomerNumber());
[Code] ....
For some reason one does work but the other does not work it says syntax error near order (table name). I am using sqlite db ...
For my jsp file, the code editor shows no error, but the projects window shows an error. I built my project again, cleaned the project, restart eclipse twice and summoned cthulhu. But my project still shows an error. How do I find the cause.

I have put error.jsp and badpage.jsp file in public access folder that is web content in eclipsewhen I am running the code I am status code of 500 and not the errorpage.jsp message .
So I am finishing up a GUI that randomly rolls a dice and shows you the dice face from a file that I have on my computer. It compiles fine, but when I open the GUI and press the button "Roll" it gives me errors and does not display the images.
I am pretty new to Java and I am working on a sample Search code from my textbook. I can't figure out why I am getting the following error because I copied the sample exactly as it is in the book. The error is illegal start of expression on the second to last line.
public class Search { public static final int NOT_FOUND = -1; public static int binarySearch( int [] a, int x ) { int low = 0; int high = a.length - 1; int mid;
the system I am using is blue jay and java. my problem is that I have this error message pop up whenever I try to compile any of my 6 classes. Three of the classes are cities, 3 others are shops, and the final one is a inventory called Player. The following is the error code that appears when I try to compile class THshopB or class CityB.
method run in class CityB cannot be applied to given types;required: Player; found: no arguments; reason: actual and formal argument lists differ in length
A similar error occurs for the rest of my City and THshop classes,except it replaces the class CityB with CityA and occurs in class THshopA, replaces CityB with CityC when occurring in class THshopC.The public methods of CityB and THshopB are shown below, as I believe that something is wrong with the public method of one or the other. I have the code [CItyB.run();}] inside of class THshopB, and run is the part that gets the red highlight error described above.THshopB public method
[ public static void shop(Player inventory){ CityB.run();}] CityB public method [ public static void run(Player inventory){ THshopB.shop(inventory);]
All of my THshop classes are written in the same format, and all of my City classes are written in the same format,
There are 2 methods and a main one. The first is a void that creates a 3x4 2d array and the second is to search for a value in the array, if found it will return the number of the row that contains that value. If not, it will return -1, but I am getting 1 error and 1 dead code warning.I will put comments at the lines that contain the problems
import java.util.Scanner; class Question4{ public static void main(String[]args){ Scanner s = new Scanner(System.in); int x,n; System.out.println("Please input the value that will be used in the array"); x=s.nextInt(); System.out.println("What is the value you want to search for?"); n=s.nextInt(); createArray (x,n);
