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.

cannot find symbol method append (String)

I don't get it why it says it cannot find symbol append.
do i need to use Stringbuffer? i got this code on a tutorial for receipts from youtube, and the uploader disabled comments so I can't ask him directly. please help me. Im still an amateur at java.
Tell me if I need to post my whole code or what code would you want to see to see errors. thanks in adv.
Calendar timer = Calendar.getInstance();
timer.getTime();
SimpleDateFormat tTime = new SimpleDateFormat("HH:mm:ss");
tTime.format(timer.getTime());
SimpleDateFormat Tdate = new SimpleDateFormat("dd-MMM-yyyy");
Tdate.format(timer.getTime());
jtxtReceipt.append("\ Water Station Receipt:\n" +
"Reference:\t\t\t" + refs +
"\n=========================================\n" +
"Mineral:\t\t\t" + jtxtMineral.getText() + "\n\n" +
"Purified:\t\t\t" + jtxtPurified.getText() + "\n\n" +
"Travel:\t\t\t" + jtxtTravel.getText() + "\n\n" +
"VAT:\t\t\t" + jtxtVat.getText() + "\n"+
"\n========================================\n" + "\n" +
"Tax:\t\t\t" + jtxtTax2.getText() + "\n" +
"Subtotal:\t\t\t" + jtxtSubTotal.getText() + "\n" +
"Total:\t\t\t" + jtxtTotal.getText() + "\n" +
"===========================================" +
"\nDate:" + Tdate.format(timer.getTime()) +
"\ntTime:" + tTime.format(timer.getTime()) +
"\n\t\tThank you ");

The append method doesn't exist in the String class. You can either user a StringBuilder to do the job, or if it's a light concatenation, just use the + operator

The append method doesn't work on TextField Palette. So, if You're on TextField Palette, replacing that with TextArea Palette should solve the problem.

Load all items from a list of string, launching minecraft with libraries listed in the files list

I'm making a launcher, this launcher using process with java, my problem is, I have a list(of string) called "files", I want to build the process with -cp all items from this unknow count list. I want to launch minecraft, in the "files", my launcher stored the libraries.
With more code details:
MainClass: The minecraft's main class,
JavaPath: The java location in the computer,
MaxMemAlloc: The maximal heap size for java,
MinMemAlloc: The minimal heap size for java,
Version: The minecraft version
My code looks like this:
Dim p As New Process()
p.StartInfo.FileName = Javapath
p.StartInfo.Arguments = " -Xms" + MinMemAlloc + "M -Xmx" + MaxMemAlloc + "M " +
"-Djava.library.path=" + Root + String.Format("\versions\{0}\{0}-natives", Version) +
" -cp " +
String.Join(";", Files) +
Root + String.Format("\versions\{0}\{0}.jar ", Version) + MainClass +
" --username=" + Username +
" --version " + Version +
" --gameDir " + Root +
" --assetsDir " + Root + "\assets" +
" --assetIndex " + AssetIndex +
" --accessToken null" +
" --userProperties {}" +
" --userType mojang" +
" --uuid (Default)"
p.StartInfo.WorkingDirectory = Root
p.StartInfo.CreateNoWindow = False
p.StartInfo.UseShellExecute = False
p.EnableRaisingEvents = True
Application.DoEvents()
p.StartInfo.RedirectStandardError = True
p.StartInfo.RedirectStandardOutput = True
AddHandler p.ErrorDataReceived, AddressOf Main.p_OutputDataReceived
AddHandler p.OutputDataReceived, AddressOf Main.p_OutputDataReceived
p.Start()
How to scroll and -cp all items from the "files", and launch the process? Thanks!

You can use the String.Join method to easily get a delimiter-separated string from a list.
" -cp " +
String.Join(";", Files) + ' other stuff
E.g. if your list has asdf and qwer, it will output asdf;qwer.

SOAP client SAAJ

I am relatively new to SOAP and wanted to write a SOAP client in JAVA. I figured out that the WSDL has a lot of other crap and as I use just one service out of it, hence SAAJ would be the shortest way. The first WSDL I got was RPC encoded and did not support SSL connections (http link). The call I made was this:
String request = "<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:AxessInterface\">"
+ " <soapenv:Header/>"
+ " <soapenv:Body>"
+ " <urn:getModemFromACS soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">"
+ "<ModemIDMACAddressChoice xsi:type=\"urn:ModemIDMACAddressChoiceStruct\">"
+ " <ModemID xsi:type=\"xsd:string\">"
+ modemId
+ "</ModemID>"
+ " </ModemIDMACAddressChoice>"
+ " </urn:getModemFromACS>"
+ " </soapenv:Body>"
+ "</soapenv:Envelope>";
The new WSDL that I have is I guess NOT RPC encoded (it does not have that "style=rpc" tag anywhere) and the link is SSL enabled (https with one way authentication). The style is "document" in this WSDL.
I have a couple of issues:
My soap call doesnt work. I modified it to be:
String request = "http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:AxessInterface\">"
+ " "
+ " "
+ " "
+ " "
+ " "
+ modemId
+ ""
+ " "
+ " "
+ " "
+ "";
I am not sure why the code cannot be displayed, i removed the line "soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" . With this i get a SOAPFault with message: "list index out of range"
Can someone tell me how to add that truststore to my SOAP client? (I use System.setProperty but I am not sure if this is the best way to go).

How can I split the data over multiple lines in a JTextArea?

How can I put each line of the host in the message body? I work with a JTextArea.
String host = InetAddress.getLocalHost().getHostName().toString();
texto_recepcion.setText(host + texto_recepcion.getText() + dpRecepcion.getAddress() + " " + mensaje_recibido + "\n");
How it is now:

I resolve my question with append function.
String host = InetAddress.getLocalHost().getHostName().toString();
texto_recepcion.append(host); // ***Use the function append for solve the problem***
texto_recepcion.setText(texto_recepcion.getText() + dpRecepcion.getAddress() + " " + mensaje_recibido + "\n");
Thanks a lot

Why don't you add the newline character "\n" to the beginning of the string?
texto_recepcion.setText("\n" + host + texto_recepcion.getText() + dpRecepcion.getAddress() + " " + mensaje_recibido);
