While executing my application i came across with this unexpected error which i don't know why?

I'm working on a program and can't seem to fix my for loop error.I get an error at the for loop line saying illegal start of expression and i don't know how to fix it:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */
public static void main(String[] args) { Scanner Keyboard = new Scanner(System.in); System.out.print("Please enter your name."); String name = Keyboard.next(); name = "name";
Implementation of the nested for loop. I thought it was going to go smoothly but apparently not.Purpose: This program is meant to print out all the prime numbers up to a certain range using the algorithm Sieve of Eratosthenes.
Update output: Works as expected.
Java Code:
import java.util.Scanner; import java.util.ArrayList; public class PrimeFactors { static ArrayList<Double> primeList = new ArrayList<>(); static double range = 0; static double maxPrime = 0; static double primeTester = 0;
This is a program to input a sentence and print the words that start with a vowel.......There is no syntax error but on executing and typing the sentence and pressing enter,I get a error saying :
java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at sentence.main(sentence.java:22)
public class pracDraw extends JFrame { private Color red=Color.red; public int i; private Color white = Color.white; JPanel pr=new JPanel(); JTextField t=new JTextField();
[code]....
If u run it you can see that the JTextField (t1) is drawn on the panel along the line but it does so with a gray border. How do i eliminate that grey border and only draw the text field along the line and finally make the text field green after it reaches the end of line?
So, I have a gameOver() method that should when oval goes out of bounds abort game but, as soon as I start the game it runs the gameOver method. I've been looking over it for a while trying different things. I think what stood out to me is removing the abort sequence the game runs mostly as it should after, popup is closed and that if I replace game.gameOver(); with ya = -1 the ball bounces off the wall.
I am trying to make a puzzle game in java.I have made it successfully.But the problem is,when it starts its already solved.I want it to start unsolved so the user can solve it.My code is:
I am getting the error "Line 54, illegal start of expression". Line 54 is where my "for" starts. It was running ok earlier, now I can't get this error to go away?
I'm trying to get a timer to work to decrease the value of a stats bar (like Hunger Level, Energy Level), but it won't paint the bars in the first place, it won't let me start the timer (the start after t.start() is underlined) and now I'm getting an error that won't let me run it at all without putting public static void main (String [] args), even though adding it anywhere is causing other errors
public void hungerTimer () { int delay = 300; int period = 300; interval = 100; hungerBar.setValue(100); hungerBar.repaint(); timer = new Timer();
I have an applet and start some process on Windows from applet. When I start this process just from another code(test), this code works fine and process runs from rt.exec() to proc.destroy(). When I use html call for applet - process runs only for 5 seconds every time (!!!) and then just alive, doesn't work, to proc.destroy(). This is really interesting for me (newbie in applets). I think, this issue caused by AccessController. I use Windows, medium Java security lever and applet is self-signed. It asks me to 'allow', applet works.Here's the code:
I made a tiny app that saves notes to a folder within the classes directory where I created the .jar file.Let's say I wanted to add this to Java Web Start. Would I be able to transfer the jar file within a folder(s) or would I have to change the program so that It creates a new folder to save texts In automatically ? Basically , can jar files be transferred with other files/folders ?
why the complier is giving the following error message "illegal start of expression" once it reach the countSpaces method.The way I see it (and I am obviously seeing it wrong), the code is public since why not, int since it returns an int # and the method has return int in it, and static I am not too sure but I get the same error message whether or not it is included
public static void main (String args[]) { Scanner in = new Scanner(System.in); String sentence; System.out.println("type a sentence"); sentence = in.nextLine(); countSpaces (sentence);
I have a jtextfield that I want to make invisible on start. I do not see an option for that in the design side under properties. I am a VB programmer and in VB there is an option under properties to make it visible or invisible.
am trying to Develop a download manager that will improve the downloading process, by splitting big files into different parts, and download each part of the file parallel and then combine them properly Just like JDownloader not really too complex like it though but more like it especially the split download part of it. I was able to get a script from some eBook but that doesn't really solve my problem as it only downloads pause and resumes which is not really what am looking for.
I've written my program and don't know the algorithm for a postfix notation and how to make one correctly?how to start my algorithm for my enterAction actionPerformed button?
