I have developed a java GUI project. I put wrong name for my project. after some time i found it and then correct by right clicking and click rename tab.
Now i run my gui it shows old project name in title. i didnt get my new project name.. how can i change it to new name
What is wrong with my code? System.out.println prints the correct name, but it fails when i try to rename the files in a directory.

When I am trying to rename a config file, ApplicationEdition.txt, I am getting pop up window message "This action can not be completed because the file is open in Java(TM) Platform SE Binary. Close the file and try again." What does this message mean ? How do I close this file, if I don't see it open anywhere ? This file has been used when a cmd was executed, but that cmd has run successfully and its not stuck anywhere then how can this file still be open ?
View Replies View RelatedWhat are they the rename To functions and lists the class file?
View Replies View RelatedI have two files - I can get the second one to populate with the first ones data and then delete the first one. I cannot get it to then rename itself to the name of the first file. It also only hits the 'rename' section of the code providing I place system.gc in otherwise it completely skips it.
the code I use is below:
Java Code:
finally{
try {
br.close();
// mp br.close();
//mp System.gc();

I have a TabView that generates the numbers of tabs, titles and content based off of the selected project from another field. I have managed to get it to load the proper number of tabs and content, but the first tab title displays the title of the first tab from the previous query.
The jsf is:
<h:panelGroup id="equipmentWrapper">
<p:tabView effect="blind">
<c:forEach items="#{databaseViewHandler.deviceTypes}" var="deviceType">
<p:tab title="#{deviceType.key}">
<ui:include src="#{deviceType.value}"/>
[Code] ....
And the method handling the content and number of tabs:
public DatabaseViewHandler() {
deviceTypes = new LinkedHashMap();
}
public Map<String, String> getDeviceTypes() {
return this.deviceTypes;
[Code] ....
The method findAssociatedEquipment() is called when it recieves a selected project to display.
The command button calls the update for panelGroup "equipmentWrapper". It updates fine for the ui:include and generates the correct number of tabs in the correct order.
So for example the first query might only generate one tab for an 881 device. Then if you select a project that should have a 2911 and 2960 it will correctly load both, but the title for the first tab will retain 881. Should you select a third it will have the title 2911 from the second project.
I change TreeTableColumn.text but I got a Exception
Exception in thread "JavaFX Application Thread" java.lang.ClassCastException:
javafx.scene.control.TreeTableColumn cannot be cast to javafx.scene.control.TableColumn
at com.sun.javafx.scene.control.skin.TableHeaderRow$10.invalidated(TableHeaderRow.java:277)
so I check TableHeaderRow . I find this method
private final InvalidationListener columnTextListener = new InvalidationListener() {
@Override public void invalidated(Observable observable) {
TableColumn<?,?> column = (TableColumn<?,?>) ((StringProperty)observable).getBean();
CheckMenuItem menuItem = columnMenuItems.get(column);
if (menuItem != null) {
menuItem.setText(getText(column.getText(), column));
}
}
};
why don't they use this
TableColumnBase<?,?> column = (TableColumnBase<?,?>) ((StringProperty)observable).getBean();
i want to check my array for a title, if the title is there i want to call a method, if the title is not there i want an error message. I am not sure how to get this. i think my code would work if it didn't always finish the method. for example if true the method stops and does run whats after the for loop. but that isn't happening.
void markItemOnLoan(String title, String name, String date){
int i=0;
for (i = 0; i < numberOfItems; i++){
if (items[i].getTitle().equals(title)){
items[i].markOnLoan(name,date);
}
}
System.out.println("ERROR: Can not find that item. ");
}
I developed a simple java gui . On running a frame opens with 5 buttons and each button opens another frame when selected. There are no errors and frames open and close as required however i see that only the main program frame has the icon and title that i assigned and the frames bieng called through the buttons have the default frame with java icon and no title although it's been specified in the code of these called frames. When these called frames are executed individually though the program the title and icon are displayed.
View Replies View RelatedI am familiar with php, but I don't know Java. We need a program, that will be able to scrape large amount of title tags from large sites, fast. I've been trying Seo Spider by Screaming Frog, and Xenu's Link Sleuth, but these programs are not good enough. They hang up, they save all the data in RAM, I think, and after a relatively short period of scraping, they stop working, become unresponsive, and so on.
Somebody recommended me getting a custom made program in Java, which would be able to scrape title tags only, from large sites (I am talking 25 - 50 million pages or more). I was told that it would not have a graphic interface, or anything like that. Nothing like this is needed too, we just need to have title tags.
In a text file, I have individual titles (starting with ">" character), and under those titles, I have calculated values for a Counter. I want to search the entire text file for the highest counter under every title. After I get the highest counter, I would like to print it's title, name of the counter, and counter value. Example of the code I already have:
int letterCounter;
String line;
if (line.startsWith (">")) {
bw.write ("");
bw.write (line);
} else {
//code that counts how many total letters (letterCounter) under title
}
I am just trying to use basic concepts.
Sample of my text file:
>gi 91206428 ref NP_001035160.1 seven transmembrane helix receptor precursor [Homo sapiens]
letterCounter is 43
>gi 157412240 ref NP_001094800.1 C1GALT1-specific chaperone 1-like [Homo sapiens]
letterCounter is 7
>gi 117938299 ref NP_001071105.1 RAB6C-like [Homo sapiens]
letterCounter is 109
Sample of desired output:
>gi 117938299 ref NP_001071105.1 RAB6C-like [Homo sapiens]
letterCounter is 109
I need to turn some strings from:
'1-the-high-street'
to:
'1 The High Street'
But...
if string is
'the-dog-and-duck'
I want to achieve
'The Dog and Duck'
...whereby the 'and' is NOT converted to title case
My code as follows:
String propertyPageTitle = "1-the-high-street";
propertyPageTitle = propertyPageTitle.replace("-", " ");
propertyPageTitle = WordUtils.capitalizeFully(propertyPageTitle);
System.out.println(propertyPageTitle);
prints: '1 The High Street'
How could I handle the second scenario so it does not convert 'and' to titlecase?
I am trying to remove a line based on user input. myFile.txt looks like:
Matt
Brian
John
However when I enter "Brian" (to remove this line), It is deleted on the temp file (myTempFile.txt), but not renamed back to the original file (myFile).
