How To Write / Save Multiple Lines Of Text To SVG File
Jul 2, 2014
I am writing to a file coordinates of texts using PathIterator (Java Platform SE 7 ) saved as SVG format i defined the Font attributes using AttributedString (Java Platform SE 7 ) and TextLayout (Java Platform SE 8 ). It is saving to the file and working properly, but it is just writing as a single line of text where is my target is multiple lines of text, i began using LineBreakMeasurer (Java Platform SE 7 ) Class, but some text is removed plus i got single line of text only, where i face the problem that , How to determine the width to get multiple lines of text ? i tried to figure out from this exampleDrawing Multiple Lines of Text (The Java - Tutorials > 2D Graphics > Working with Text APIs) where is drawing multiple lines of text but i am using getBounds().getWidth() of TextLayout object the code i tried

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.
I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?

I have a text file with the below details and we get the input as name CONNECTION_PORT and we need to delete the matching global variable which as CONNECTION_PORT and keep the remaining global variable in file without using any temp files.
for example
input:
CONNECTION_PORT
Text file
<globalVariable>
<name>CERTIFICATE_PASSWORD</name>
<value>fgfdgfgf</value>
<deploymentSettable>true</deploymentSettable>
<serviceSettable>false</serviceSettable>
<type>Password</type>

I need to write the same data to stdout and to a save file. In C I'd do something like:
void doWrite(int fd, char *stuff) {
fprintf(fd, stuff);
}
if(someFlag)
doWrite(STDOUT, data[]);
doWrite(saveFd, data[]);
Google shows me how to use file I/O, and how to use stdio, but not how to combine the two easily.
With my *nix command line I could "program file | tee savefile", but savefile holds the result of prior runs, gets read before I parse 'file', and this command line zero's out savefile before the program can read it.
The data is standard ASCII, I doubt I'll ever have 20k of data.

New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.

This part of the code searches for every word in the text file and saves it to an ArrayList. It searches for the word if its valid of not.How can I offer a list of similar words when the word that the user inputs is not in the dictionary. Also I want it to prompt the user to accept the word or enter a replacement that gets saved in the dictionary.
package spellChecker.project1;
import java.io.FileNotFoundException;
import java.io.FileReader;

I can't seem to understand how to change certain line of text, inputted from a file. For this I really don't know where to begin. I have got the input from the file. But I want to change like very other line in the file. Can't seem to understand how this could be done. Is there away to access specific lines from the file and edit them? So far, i have this:
import java.util.*;
import java.io.*;
public class ChangeEveryOtherLine {
public static void main(String[] args){
//Constructing file object representing input file
File inputFile = new File("input.txt");

For example, if I had a text file with one line such as "first, second, third", would there be a way to make it so I could make "first" go to the first array list, "second" to the second, and "third" to the third?
I haven't posted any of my code so far as it wouldn't be right to be handed the finished code on a platter and I should put the work into it, but I'd just need a loop to make it go through the rest of the lines in the text file to add all the first, second and third parts of each line, right?
(I already know how to input data from a file, but not how to split up a line into bits to put into different array lists).

So I am calling this method several times and trying to write multiple records to a file. Problem is that every time I call the method it overwrites the file from before and doesn't add it.
public void fileWriterMethod() throws IOException{
RandomAccessFile raf = new RandomAccessFile(filename, "rw");
raf.writeInt(id);
raf.writeInt(existingMileage);
raf.writeInt(gasCost);
raf.writeInt(ndays);
raf.writeInt(rate);

I need to write out multiple BufferedImages to a single tiff file. Each image represents a seismic time slice which can be several megabytes in size. I have used the TIFFEncodeParam.setExtraImages method and saved all my BufferedImages to a vector but my since I create so many BIs I keep running out of memory. Is there a way to create a BI, write it out to a TIFF file, then discard the BI and create the next one?

I wanna learn to create a method where I use a scanner or any other way to input.The stuffs I input will be strings. The whole thing will be like a destination creator.So if I input the string USA, it will write this to a file:
1:USA
When I go to the method again the ID will be added so if I input UK, the file will contain:
1:USA
2:UK
Now if I terminate the program, next time when I run it again it will be able to read the ArrayList, so if I wanna go to the method again and write: Norway the file will contain:
1:USA
2:UK
3:Norway
Later I also want to be able to use println to show all of these lines from the file, as well I would like to be able to delete an ID, so if I delete ID 2 the file would contain:
1:USA
3:Norway
I'm quite new to Java, I'm in a Java course since soon 3 weeks back and I have sure learned a lot, all the loops and basic statements that exist in most languages, but now when it comes to this I just don't understand.

I need to write a program where the user inputs name, age, email, and cell and write the user inputs to a text file. I need to have it so the file can be added to if more than one set of information is added. Currently, every time I click the button, the file is overwritten instead of added to. How do I correct this? Current code is as follows:
try
{
FileWriter writer = new FileWriter("ContactInformation.txt");
BufferedWriter bw = new BufferedWriter(writer);
nameTextField.write(bw);
bw.newLine();
ageTextField.write(bw);
bw.newLine();
emailTextField.write(bw);
bw.newLine();
cellTextField.write(bw);
bw.newLine();
bw.close();
nameTextField.setText("");
ageTextField.setText("");
emailTextField.setText("");
cellTextField.setText("");
nameTextField.requestFocus();
}

I am trying to write to a text file with information stored like this.
brick 500
stone 500
And so on. Here is the code I am using to write to the file.
switch(record){
case "brick":
x.format("%s%n", "brick " + value);
closeFile();
break;
case "log":
x.format("
%s%n", "log " + value);
closeFile();
break;
When I write like this, putting deletes the first line. What I can look into or other functions that would be useful?

a. Assume that we have a list of employees' names of a company and their ages. Write a program that reads from the user several lines of input. Each line includes an employee's name and his/her age (as an integer). The program should calculate and print the following:
- The average age of all employees (rounded to 2 decimal places).
- The oldest employee and his/her age.
Hints:
You could assume that the user will insert valid data and at least one employee.
You could assume that the oldest employee is only one person.
User could stop the program via entering the word "end" as an employee's name.
Sample Input and Output: In each line, insert an employee's name and his/her age To halt the program, insert "end" as an employee's name
Adam 30
Tom 41
Ted 45
Karl 30
end
The average age of all employees is 36.50.The oldest employee is Hisham whose age is 45

I have created an application using hibernate and struts.In which a form is created where the user will enter all its personal details(for e.g name ,phone no. and address).
Here for address I have used textarea and whenever user enters the address, sometimes it can be a long string also.
So the problem is if a long string is entered then while displaying that ,address comes on single line and the page is stretched.
how to break this single string into mutiple lines in java class?
