I need to insert a break line to a text message on hitting enter by taking its ascii value i.e 10.I have used node.insert commands.I have tried using node.insertAttribute and node.insertChars but is not working ....
View RepliesI am checking how to do following task.
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?
I have wrote this class who read from text line by line and save the words in fileOnTable.. Now i don't know what to read in ReadOffer to save the words in object offers and return this.. One more question.. What JUnit test can write for this code..?

It's not doing anything, I don't understand why.
I am learning Java on my own, and I am creating little programs to do so.The program below asks the user to input text and hit enter. When user does that, it asks if that is correct. If the user enters "y," the program ends. That's good.If the users enters "n," the strGrategul is set to empty which triggers the while statement to start over again. That's good. However, when the program asks the user to "Tell me one thing you are grateful for..." it doesn't wait for user input. Instead it skips to "You said ''? Enter 'y' or 'n'" It thinks the user enter an empty line.
public static void main(String[] args) {
String strGrateful = "";
String strGoal = "";
String strContinue = "";
Scanner scn = new Scanner(System.in);

Write a program that reads in a line of text and then outputs that line of text first in all uppercase letters and then in all lowercase letters.
INPUT and PROMPTS. The program prompts for a line of text as follows: "Enter the text: " and then reads in an entire line of text as a String .
OUTPUT . There are four lines of output . The first line is "The text in all upper case is: ". The second line is the line that was read in, displayed in all uppercase. The third line is "The text in all lower case is: " and the fourth line is the original line that was read in, displayed in all lowercase.
CLASS NAMES. Your program class should be called ShoutAndWhisper.
This is what I have so far:
import java.util.Scanner;
public class ShoutAndWhisper
{
public static void main(String[] args)
{
Scanner scannerObject = new Scanner (System.in);
System.out.println("Enter the text: ");
scannerObject.next();
System.out.println("The text in all upper case is: ");

i am working on a love project and i have to print different different text messages on the basis of different different values .
i only try to know which method i used for this...
like on jsp page
i get a value 42 then onclick <next page>print a text message about the 42
I am working on a project and i want to print some text message when i get a numeric value.
Like....if the output value is 10 then Click <Next Button> go to next page and print "This is a number which comes before 11".
for this which method will use and how can i implement it in my project.
I can't catch the text message from a exception because ex.getMessage() is null.
Code is
try {
.......
} catch (Exception ex) {
System.out.println("Error "+ex.getMessage());
Logger.getLogger(Soap.class.getName()).log(Level.SEVERE, null, ex);
statD.errMessage = ex.getMessage();
statD.succes = false;
return statD;
}
And the program writes at the console:
Error null
Also on the console screen I can see the following message:
Apr 10, 2014 3:00:38 PM SoapUtils.Soap setPostVarsSEVERE: nulljava.lang.NullPointerException at SoapUtils.Soap.setPostVars(Soap.java:830)
Line 830 of Soap.java is inside the try {}.
Why is the ex.getMesage() null?

View Replies View RelatedI have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.

I'm trying to print the information entered into my TimeClockApp to a text file named timeclock.txt. Everything is writing to the text file, except instead of adding each part of the run through the app to one line, it is saving each part on a separate line like this:
i

To ensure that each run through the time clock is recorded on a different line in the text file, I want it to add each item like this instead:
i 3 2014/06/08 15:32:29
I have tried to execute the
out.println(timeClock.get(i)); line as out.println(timeClock.get(i) + " "); and out.println(timeClock.get(i) + "

how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

How to output text to a file, so I had to do my own research on google, but the results I found were confusing. I finally got my code to write to a file, but I cannot figure out how to append a new line. I know what part of the code is incorrect, but I don't know how to fix it. here is what I have right now:
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Scanner;
public class highscore {
public static void main(String[] args) throws IOException {
[Code] ....
I can see the last two lines are telling the program to overwrite the first input with the second. Of course if I pick a different file name for the second output, I get another file with the second input, but I need to learn how to append as well.
I have a code that imports a text file [URL] .... and has a variety of methods for sorting through it. The file is structured differently when loaded into the environment, as each line begins with a movie and lists all of its actors. Each line has a movie title, then its release date in parentheses, and then the actors in the movie all listed and separated by slashes (Ex: /lastname 1, firstname 1/lastname 2, firstname 2/etc.....
Well I tried to create a method to search all the actors in the file for an inputted word and return the ones that have that word somewhere in their names. I managed to get it to work, but the code only runs for one line of it. How should I get this to do what its doing, but for EVERY line?
Code is here: [URL] ....

So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like
