How Html works to create a jLable in java - java

Since it is an array it repeats till the end of the loop. But Room 1 should not be repeated . it should be place at the top
first[ind] = new JLabel("<html>"
+ "<body>"
+ "<div id=r12style=border: 3px solid orange; margin-bottom: 5px;>"
+ " <h2>"
+ " Room 1"
+ " </h2>"
+ "<img src=" + icon + " width=\"95\" height=\"105\"></img>"
+ "</div>"
+ "</body>"
+ "</html>");

Try this (I haven't tested it):
IMM[ind] = new JLabel("<html><style >#aa {margin-left:25px;}</style>"
+ "<div id=\"aa\"></font><font color=\"rgb(0,0,0)\"size=\"5\">"
+ bed_no + "<font color=\"rgb(255, 204, 204, 150)\"size=\"1\">.</div></font></html>"
, "<html><img src=" + icon + "></html>", JLabel.LEFT_ALIGNMENT);
If you want the text under the icon:
IMM[ind].setHorizontalTextPosition(JLabel.CENTER);
IMM[ind].setVerticalTextPosition(JLabel.BOTTOM);
Edit - It's probably a good idea to break up the JLabel text by using a String variable. Because it looks almost unreadable.

how do i edit HTML inside string JAVA CODE easily

i developed android app and i used HTML code to Print the result in formatted form.
the code will be like this :
String adress = editText1.getText().toString();
String phone = editText2.getText().toString();
String licenseNo = editText3.getText().toString();
"\n" +
" <div class=\"down\">\n" +
" <div class=\"EASY\">\n" +
" <img src=\"" + image + "\" alt=\"QR\" >\n" +
" </div>\n" +
" <table class=\" info_table\">\n" +
" <tbody>\n" +
" <tr>\n" +
" <td class=\"info\">" + phone + "</td>\n" +
" <td class=\"info\"> " + licenseNo + "</td>\n" +
" </tr>\n" +
" <tr>\n" +
" <td class=\"info_A\" colspan=\"2\"> " + adress + "</td>\n" +
" </tr>\n" +
" </tbody>\n" +
" </table>\n" +
" </div>";
as you see it should contain \n and + because its inside a string object contained variable values from user input.
i faced some difficulty when i need to Edit this Piece of code cose i will test it inside the application.
my question is what is the best way to get this code to edit and preview it outside android studio and reinsert it again.
i used find and replace but it make some problems.
hope i explained enough
You can create a XML file in the resources folder, read it and then use format in order to change the values there.

getting wrong arabic translation in PDF iText

I am generating PDF file from my HTML string, But when PDF file getting generated the content in HTML and PDF does not match. The content is PDF is some random content. I read about the issue on google and they suggest using Unicode notation like %u0627%u0646%u0627%20%u0627%u0633%u0645%u0649%20%u0639%u0628%u062F%u0627%u0644%u0644%u0647. But I am putting this into my HTML it is getting printing as it is.

It's difficult to determine what the issue is exactly without seeing the faulty output. But your "random content" sounds like an encoding issue.
Since you have your Arabic content directly in your source code, you have to be careful about encoding. For example, using ISO-8859-1, the resulting PDF output is:
Using Unicode escape sequences (\uXXXX), you can indeed avoid some of these encoding issues. Replacing
" <p> انا اسمى عبدالله\n" +
with
" <p>\u0627\u0646\u0627 \u0627\u0633\u0645\u0649 \u0639\u0628\u062F\u0627\u0644\u0644" +
results in Arabic glyphs, even when using ISO-8859-1 encoding. Alternatively, you can use UTF-8 to get the correct content regardless of the use of Unicode escape sequences.
When your encoding issues are solved, you will likely get output like this:
For correct rendering of certain writing systems, an optional module pdfCalligraph is needed for iText 7. With this module enabled, the resulting output looks like this:
The code used for the tests above:
public static void main(String[] args) throws IOException {
// Needed for pdfCalligraph
LicenseKey.loadLicenseFile("all-products.xml");
File pdfFile = new File("java19.pdf");
OutputStream outputStream = new FileOutputStream(pdfFile);
String htmlSource = getContent();
ConverterProperties converterProperties = new ConverterProperties();
FontProvider dfp = new DefaultFontProvider(true, false, false);
dfp.addFont("/Library/Fonts/Arial.ttf");

Please check to make sure that your sourcefile and compiler use the same encoding, e.g. UTF-8. I sometimes check that by including characters that are only available in unicode and not in other classic codepages.
I tried to reproduce the issue and I got the following warning in the logging when running the example code:
Cannot find pdfCalligraph module, which was implicitly required by one of the layout properties
This was already mentioned by Alexsey Subach and can cause the following issue:
Problems with text direction (I am no expert on Arabic but the text was aligned to the right)
Wrong combination of characters (For the details see this document: https://itextpdf.com/sites/default/files/2018-12/iText_pdfCalligraph_4pager.pdf )
This is the output I got without pdfCalligraph:
pdf result without calligraph
Created with the codebase on this repository
So in order to get everything to work perfectly like your browser does with the HTML for Arabic you will also need:
A commercial license for https://itextpdf.com/en/products/itext-7/pdfcalligraph
Code to load the license file (or you will get a LicenseFileNotLoadedException )
This dependency https://repo.itextsupport.com/releases/com/itextpdf/typography/2.0.6/
Your question is tagged as regarding iText7 but there may be other possible free alternatives depending on your requirements like Apache FOP that should work with Arabic Ligatures according to this source but probably require rework as it is based on XSL-FO. In theory you could generate the XSL-FO with any templating mechanism that you currently use e.g.: JSP/JSF/Thymeleaf etc. and use something like a ServletFilter to convert the XSL-FO to a PDF on the fly during a request (in a web application)
Make sure your fonts support the characters you need and if you use Maven resource directory to include extra fonts during the build check that the font file is not filtered (properties replacement) as that corrupts the file: Maven corrupting binary files in source/main/resources when building jar

How to append html text to JLabel in Java Swing

I'm trying to append text with HTML tags to text that is already in a JLabel and also has HTML tags
public class BattleConsoleUI {
private JLabel battleInfo = new JLabel("<html> Hello World <br></html>");
battleInfo.setText(battleInfo.getText() +
"<html> HERO NAME : " +
"<br> HERO CLASS : " +
"<br> HERO LEVEL : " +
"<br> XP : " +
"<br> ATTACK POINTS : " +
"<br> DEFENCE POINTS : " +
"<br> HIT POINTS : " +
"</html>");
}
I'm expecting it to display Hello World plus the appended text but the rest of the text is not displayed because of the first closing HTML tag
Quick solution is to avoid writing </html> at the end of the text. Swing needs only the opening tag <html> in order to show HTML text. Something like:
label.setText("<html>first text");
label.setText(label.getText() + " this is second"); //Still an HTML text
If you insist of closing the HTML tag and using </html> at the end, you will have to replace it before appending the new text:
label.setText(label.getText().replaceAll("</html>","") + "i append a text</html>");
Of course instead of replaceAll you could use substring and other things, but this is what i would use.
You are making the variable itself to be first set and then again inside that get text. You can do simple thing is that make two different string variable and set them to jlabel. As per here you can :
String htmlstr1 = "html hello world tag";
String htmlstr2 = "<html> HERO NAME : "
+
"<br> HERO CLASS : " +
"<br> HERO LEVEL : " +
"<br> XP : " +
"<br> ATTACK POINTS : " +
"<br> DEFENCE POINTS : " +
"<br> HIT POINTS : " + "</html>");
Jlabel.setText(htmlstr1+htmlstr2):

How can I add a newline character to a String in Java?

In a Java application, I am creating a String like below (by concatenation):
String notaCorrente = dataOdierna + " - " + testoNotaCorrente;
My problem is that I want to add also something like an HTML newline character at the end of this String (that will be shown into an HTML page).
How can I implement it?
The newline character in Java is "\n" which will look like this:
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + "\n";
However, this will not display as you expect on your HTML page. You can try adding an html break tag, or add the
(Line Feed) and 
 (Carriage Return) HTML entities:
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + "<br>";
or
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + "
&#10";
For a newline that will result in a line break in HTML, use
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + "<br>";
For a newline that will result in a line break in your text editor, use
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + System.lineSeparator();
And for both, use
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + "<br>" + System.lineSeparator();
Why not \n?
\n is specific to certain operating systems, while others use \r\n. System.lineSeparator() will get you the one that is relevant to the system where you are executing your application. See the documentation for more info on this function, and Wikipedia for more info on newlines in general.
Simply, need to add <br/> (break line tag of HTML).
String notaCorrente = dataOdierna + " - " + testoNotaCorrente + "<br/>";
so, while you are going to display this content, <br/> tag will rendered on HTML page in form of new line.

Create HTML in java with background image

I have created an html string in which I need to set the background image.
protected void onPostExecute(HashMap<String,String> hPlaceDetails){
String backgroundImage = ??????
String name = hPlaceDetails.get("name");
String icon = hPlaceDetails.get("icon");
String vicinity = hPlaceDetails.get("vicinity");
String lat = hPlaceDetails.get("lat");
String lng = hPlaceDetails.get("lng");
String formatted_address = hPlaceDetails.get("formatted_address");
String formatted_phone = hPlaceDetails.get("formatted_phone");
String website = hPlaceDetails.get("website");
String rating = hPlaceDetails.get("rating");
String international_phone_number = hPlaceDetails.get("international_phone_number");
String url = hPlaceDetails.get("url");
String mimeType = "text/html";
String encoding = "utf-8";
String data = "<html>"+
"<body background="+backgroundImage+"><img style='float:left' src="+icon+" /><h1><center>"+name+"</center></h1>" +
"<br style='clear:both' />" +
"<hr />"+
"<p>Vicinity : " + vicinity + "</p>" +
"<p>Location : " + lat + "," + lng + "</p>" +
"<p>Address : " + formatted_address + "</p>" +
"<p>Phone : " + formatted_phone + "</p>" +
"<p>Website : " + website + "</p>" +
"<p>Rating : " + rating + "</p>" +
"<p>International Phone : " + international_phone_number + "</p>" +
"<p>URL : <a href='" + url + "'>" + url + "</p>" +
"</body></html>";
// Setting the data in WebView
mWvPlaceDetails.loadDataWithBaseURL("", data, mimeType, encoding, "");
}
Note: I have my background image (background9.png) in the location MyProject/res/drawable-xhdpi. Please suggest how I need to set
<body background="+backgroundImage+">
Instead of using \res\drawable-xhdp\background9.png as the path as you mentioned in your comment, you should use:
<body background='file:///android_res/drawable/background9.png'>
I've just tested this and it works perfectly.
Please add a tag for android to clarify your question.
Anyway, you need to get a reference for your parent layout, by using findViewById(R.id.yourActivitysParentLayout)
You need then to set it's background using a ResourceManager. From the top of my head, the method name you will need is yourparent.setBackgroungDrawable(drawable). The drawable can be obtained from a resource manager instance.
This can all be avoided by setting it's background in the xml if possible by using android:background="#drawable/background9" //sorry not sure if .png is needed. xhdp is not though.
