Diamond In A Square Grid Of Dots
Nov 14, 2014I am new to java and i am trying to make a Java application which prints a diamond in a square grid of dots whose side length is input to the application.When you run the code is should be like this:
..*..
.*.*.
*...*
.*.*.
..*..
My java code print this:
..*..
.***.
*****
.***.
..*..
Here is my code:
class Main {
public static void main(String args[]) {
System.out.println("#Enter size of Diamond :");
int longestRow = BIO.getInt();
for(int row=1 ; row<=longestRow ; ++row)

Syntax For Array Of Objects
Apr 10, 2014I know the first line below creates an object but the second line creates an array of cars, I'm just not sure how it does that. I can see sportsCar is one object in the array but the others are written in a different way. It seems there should a couple names there instead. Please explain the syntax in this code that's highlighted. I don't know how to make sense of it and I've read through the book where I got it where it explained creating objects.
Auto sportsCar = new Auto("Ferrari", 0, 0.0);
Auto [] cars = {new auto("BMW", 100, 15.0), sportsCar, new Auto()};
Syntax Highlighting In Editor?
Jun 11, 2014Here is the original code I found on StackOverFlow. It highlights some specific words in a JTextPane.
import javax.swing.*;
import java.awt.*;
import javax.swing.text.*;
public class ColorChangeWhileTyping extends JFrame{
private int findLastNonWordChar (String text, int index) {
while (--index >= 0) {
if (String.valueOf(text.charAt(index)).matches("W")) {
[code]....
I dont know for some reason it doesnt work correctly. The colour goes away after I press Space to write the next word.
If Statement Syntax Error
Dec 13, 2014This 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
Syntax Error On Token
May 12, 2014So 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();

Find Whole Syntax Of API Method Online?
Jul 5, 2014I was trying to find the complete readLine() method In the online docs but all I can get hold of Is:
readLine
public String readLine()
throws IOException
Reads a line of text. A line is considered to be terminated by any one of a line feed
('
'), a carriage return ('
'),
or a carriage return followed immediately by a linefeed.
Returns:A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reachedThrows:IOException - If an I/O error occursSee Also:Files.readAllLines(java.nio.file.Path, java.nio.charset.Charset)
Is It possible to view the actual method syntax online ?
Syntax Error When Testing Code

Syntax Error Within Jasper Reports In Printwhenexpression Property
Apr 11, 2015this 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.
