How to specify the file location. One way would be
PrintWriter outputFile=new PrintWriter("A:PriceList.txt");
My problem occurs when I try to specify a file location as show below
//Open an output file that appends data and does not delete it
FileWriter append_data=new FileWriter("C:hello.txt",true);
//Make a file that cvan print data into it
PrintWriter outputfile=new PrintWriter(append_data);
Apparently, I believe this is not the right way to set my own path for the file... How can I specify my file path.
One more question would be that suppose I want to specify the file location on Desktop. What the format for that?
I am writing a small app to automate some actions on my computer this requires me to open an application and click on a button I am using
Process child0 = Runtime.getRuntime().exec("/home/user/application");
to do this. The problem is every time it opens at a different lcation on the screen so i cannot click on it using the robot class due to x,y coordinates being different every time. with selenium you can use .setlocation(x,y) method but how can this be done for other applications.

As you can see instead of displaying the champion name it is displaying the memory location and I do not know how to fix it.

I'm trying to copy a exe file from one location to another. It seems simple, but I have failed to find anything about it besides coping the contents in txt files, but that does nothing for executable.
View Replies View RelatedFor some reason my code returns the memory address of the array when its a print statement with a string, but it works fine when its in a separate print statement all by itself. Why? Do I need to create a toString method that converts a char array to a String to something? The reason why I ask that is becuase on Eclipse line 10 has a warning stating "Must explicitly convert char[] to a String".
public class Ex {
private String word;
public Ex(String word) {
this.word = word;
}
public char[] Display(){
char[] wordChars = this.word.toCharArray();
return wordChars;
[Code] .....
Result:
Hello world
The word is: [C@1db9742
I also tried this, knowing that it's a long shot, but that didnt do anything...
public String toString(){
Ex ex = new Ex(this.word);
char[] word = ex.Display();
String updated = word.toString();//counter intuitive?
return updated;
}
The file (let's call it file.txt) is on the C: of my machine. I'm using :
System.out.print("Where is the file?: "); BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
And looking for the user to enter the location of the file in the console. How do I (the user) enter the path to the file in the console. I have tried everything... "C:file.txt", C:file.txt, and a million other combinations. Nothing seems to work. How does the console expect the file path to be written so it knows how to pick up the file?
I found a fun program online and something so simple is giving me an issue. I c++ it is pretty simple fix, I can just call the strings location like an array. In java this is not the case. So far i have tried:
myString.charAt();
myString.indexOf();
There are a few other I found on google but I forget at the moment. I am just trying to close the gap on a string. It was a full sentence and I used replaceAll a few times to get several words I didn't want in the file out.
My project was to create an array holding 10 integers and populate the array with 10 random numbers. Then ask the user to guess the number. Prompt the user with a while loop if their input is out of range. Determine if the users number is in the array, and display which index location the number is in. I got most of the code done but am having trouble displaying the index location.

I'm working on a small game, and I have a quick question about parsing a file. Basically, I have a utility method, which loads an XML file containing the details of all the items for the level, and then pulls the info and passes it to the Item constructor.
A snippet of the XML file is:
<item key = "Weapon1" name = "Sword" description = "A basic sword... etc" hint = "picked up SWORD" givesPlayer = "basicSword:1" bitmap = "5,5" />
And a snippet of the class is:
public class Item extends Entity {
String name;
private String description;
private String hint;
private Map<String, Integer> givesPlayer = new HashMap<>();
private boolean pickedUp;
[Code] ....
The XML file contains this field:
bitmap = "5,5"
which basically specifies a column and row where it should grab an image from, located elsewhere.
My question is this: Should I parse this "5,5" in my utility method and pass the image(s) to the constructor(// B Consturctor), or is it ok to pass the location as a String and parse it in the Constructor( // A Constructor) ?

View Replies View RelatedI am using Swing, I have a JPanel and in it there is a JTextArea and a JButton. I want the JTextArea to move when the button is clicked on. I'm Not really sure how to do the action listener for the button. at the moment the JTextArea only moves once when the button is clicked on, but i want it to move every time the button is clicked on.
This is what i have so far:
moveButton = new JButton("MOVE");
moveButton.setName("move");
moveButton.setBounds(20, 140, 70, 40);
text = new JTextArea("hello");
text.setEditable(false);
text.setBounds(x, 50, 40, 20);
panel.add(moveButton);
panel.add(text);
In the actionPerformed method this is what it does:
text.setBounds(x + 50, 50, 40, 20);
panel.add(text);
text.setVisible(true);

I need to design a class named Location for locating a maximal value and its location in a two-dimensional array. The class should contain public data fields row, column, and maxValue that store the maximal value and its indices in a two dimensional array with row and column as int type and maxValue as double type.
I need to write the following method that returns the location of the largest element in a two-dimensional array:
public static location locateLargest(double[][] a)
The return value is an instance of Location. Write a test program that prompts the user to enter a two-dimensional array and displays the location of the largest element in the array.
Here is what i get when I run
Enter the number of rows and columns of the array:
3 4
Enter the array: 23.5 35 2 10
4.5 3 45 3.5
35 44 5.5 9.6
The location of the largest element is at 00
The location of the largest element is at 01
But I need it to display this instead.
Enter the number of rows and columns of the array:
3 4
Enter the array: 23.5 35 2 10
4.5 3 45 3.5
35 44 5.5 9.6
The location of the largest element is 45 at (1,2)
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Number of rows and columns: ");
int row = input.nextInt();
int col = input.nextInt();

I am trying to upload very big files greater than 1gb. I am using MultipartConfig and HttpServletRequest.getPart(String) from servlet api. I deployed in my server and tried uploading a file and its working like a charm.
Then I went on reading about MultipartConfig in [URL] ...... I understood that when large files are uploaded it writes parts of the file to a temporary location when the threshold is reached. And later on we have to delete the temporary files using part.delete().
What if I don't want to mention the temporary location? Will something bad happen to my application while uploading big files? I don't want to mention a temporary location becasue we cant gurantee about the production environment.
is it possible to locate mobile caller location? My client wants a module to be developed to track the caller's location whenever a call is received.

I have one quick question. If you are extending the acm graphics program, how can you set the location of the entire window? All the set location methods within the graphics program only seem to set the location of graphical objects. I know with JFrames I can use the setLocationRelativeTo(null) to position the JFrame in the center. How to set the location of a graphics window.
View Replies View RelatedI am working on a project using pictures and am having some trouble. My assignment is to take a jpeg, and reflect it(over an imaginary x-axis so to speak). As this is my first time working with images, I am very lost. My approach was to take "pixel 0" and have it swap places with "pixel max". Theoretically, I believe I would only need to do this for the first 50% of the pixels, as each flip works on 2 opposite pixels. With my code thus far (the reflect() method), I print the left half of the image. Note: I must use pixel manipulation. I cannot use graphics.

I have a large JPanel which uses a GridBagLayout in which I put other JPanels inside the cells. The main JPanel is then added to a JScrollPane. What I'm looking to provide the user a way to automatically scroll to a particular item in the scrollable area (i.e. each of the child JPanels would represent - let's say a person for argument sake - and an user would like to click a button or bring that JPanel into focus / view.
The JPanels are added within a loop to the grid and references of these JPanels at the moment aren't store in an array or anything, so it's a case of being added and that's it. Also there's the case of where was the object exactly added and also how to have the scrollbar move to the proper focus location (both horizontally and vertically).
I know how to append text to a File using the true argument but I would like to be able to append to a certain line In the file.Basically I've made a simple html page with Image links to different sites.
