I know you can retrieve the username with something like System.getProperty("user.name") but I am looking for a way to retrieve the first and last name of the current user.
Is there a native Java library that does this? Or do you have to plug into the Windows API? Or maybe you have to pull it from Active Directory? This seems relatively easy with .NET but I can't find a way to do it in Java.
As Brian Roach suggested in the comments, it's pretty straight-forward to do this with JNA, since it has a built-in wrapper for Secur32 which wraps the GetUsernameEx() function (which is ultimately the system call wrapped by the .NET library you linked to above).
Use would be something like this:
import com.sun.jna.ptr.IntByReference;
import com.sun.jna.platform.win32.Secur32;
// ...
char[] name = new char[100]; // or whatever is appropriate
Secur32.INSTANCE.GetUserNameEx(
Secur32.EXTENDED_NAME_FORMAT.NameDisplay,
name,
new IntByReference(name.length)
);
String fullName = new String(name).trim();
Note that this will give you the full name in the same format as you'd get typing net user %USERNAME% /domain at the command prompt.
Or just,
String fullName = Secur32Util.getUserNameEx(Secur32.EXTENDED_NAME_FORMAT.NameDisplay);
But it is the same, as the upper answer

I'm building an app that speaks a custom message that includes the current time. I've noticed that some voices seem to parse the time correctly- that is, when I pass in a string like "The time is now 7:07" it actually speaks it as "seven-oh-seven."
However, other voices insist on saying "the time is now seven colon zero seven." It would be simple enough to write a function to parse it myself, but I'm trying to find something built-in so I won't have to worry about localization. Is there something I can do within TTS (attributed-string-related, maybe?) or even a Java library that will provide me with a localized "text" string of a time? I've dug through the TTS documentation and didn't find anything, and all the Java time-formatting patterns I've seen are numbers-only, no words.
Figured it out- the TtsSpan is what's needed. Took me a while to get the format right; there are basically zero examples out there on how to do this. Here are the basics for what worked for me, if anyone else comes across this with the same need (in kotlin):
var h:Int = Calendar.getInstance().get(Calendar.HOUR)
if (DateFormat.is24HourFormat(ApplicationContext))
h = Calendar.getInstance().get(Calendar.HOUR_OF_DAY)
val m:Int = Calendar.getInstance().get(Calendar.MINUTE)
val whenStr = getFormattedTime() // internal function I'm using to format it visually
wholeString = message.replace("|TIME|",whenStr) // my time doesn't always appear at the same place in the custom message
val spannedMsg:Spannable = SpannableString(wholeString)
val span:TtsSpan = TtsSpan.TimeBuilder(h, m).build()
spannedMsg.setSpan(span, wholeString.inexOf(whenStr),wholeString.indexOf(whenStr) + whenStr.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
tts.speak(spannedMsg, TextToSpeech.QUEUE_FLUSH, params, "UTT_ID")
According to the TtsSpan documenation page, there are plenty of other options aside from TimeBuilder, as well, so be sure to check that out if you're looking for different customizations- just be aware that there aren't any code examples.
Is there a way i can create code build code by using Concatenation in Android studio/eclipse?
In other words i have 2 sets of strings one for each country i am dealing with ZA and KE. They have 2 different EULA's.
So i would like to pull the string related to the respective country.
String message = mContext.getString(R.string.eula_string_za);
above is an example of the output code. is there someway i can go about "creating" that based on If statements?
String str = "mContext.getString(R.string.eula_string_";
if (something = "ZA") {
str += "za);";
} else {
str += "ke);";
}
so if the country selected is ZA then the output code should be
mContext.getString(R.string.eula_string_za);
and if its KE it should be
mContext.getString(R.string.eula_string_ke);
and then the result will then pull the correct string from strings.xml?
Java is a compiled code, not an executed one,you can't write code this way like in an interpreted language.
The best way to manage different languages in android is to use a string.xml file for each language.
Take a look at this tutorial, it will help you a lot :

If you want to go this route you could try to use reflection. Have a look at Class.getField(…) if you want to use reflection.
Instead of first building a code string using a if statement you can also use the same if statement to find the correct string:
String str;
if (something.equals("ZA")) {
str = mContext.getString(R.string.eula_string_za);
} else {
str = mContext.getString(R.string.eula_string_ke);
}
Note that your condition something = "ZA" does not do what you think it does: It assigns something the string "ZA" and then evaluates itself to "ZA", so this would not even compile. The correct way would be something == "ZA", but even this does not work in the general case. You need to use String.equals(…). Some even argue you should use it the other way around (i.e. "ZA".equals(something)) to avoid a NullPointerException…
Another possibility would be to first build a Map from county to the corresponding string ID for all the EULAs you have and then asking the Map to return the correct one.
But probably the cleanest solution would be to use Androids built in mechanism, as hkN suggests.
How to generate a valid UUID from a String? The String alone is not what I'm looking for. Rather, I'm looking for something like a hash function converting any String to a valid UUID.
Try this out:
String superSecretId = "f000aa01-0451-4000-b000-000000000000";
UUID.fromString(superSecretId);
I am using this in my project and it works. Make sure you import the right stuff.
In the Java core library, there's java.util.UUID.nameUUIDFromBytes(byte[]).
I wouldn't recommend it because it's UUID 3 which is based on MD5, a very broken hash function. You'd be better off finding an implementation of UUID 5, which is based on SHA-1 (better although also sort of broken).
I'm trying to write a Jena built-in to return a value from an algorithm I have been given and then do a comparison against that value, e.g.,
String rule = "[exRule: (?d rdf:type ex:abc)" +
"<-" +
// ...extract ?a, ?b to use as inputs to the rule
"greaterThan(myBuiltIn(?a, ?b), 1)" + // Is return value greater than 1
"]";
So, first the Jena documentation says that the easiest way to experiment with this is to look at the examples in the builtins directory, however I don't seem to have this in my installation, I'm using Jena 2.6.4 on Windows 7. Where can I find this? Do I need to download it from elsewhere?
Secondly, I'm unsure how to pick up the return value from my builtin. If I simply call myBuiltIn(2, 1) using hardwired values I know it's being called due to some debug output I've added to the builtin's bodyCall() method. However, if I pass it to greaterThan(), then I no longer see this. Is it still being called?
#Joshua
I found how to implement this.
First of all, you should create a new class that extend from BaseBuiltin like this http://sadl.sourceforge.net/CustomJenaBuiltins.html
and then add it into builtinRegistry class
I am using a lib which has an enum type with consts like these;
Type.SHORT
Type.LONG
Type.FLOAT
Type.STRING
While I am debugging in Eclipse, I got an error:
No enum const class Type.STRİNG
As I am using a Turkish system, there is a problem on working i>İ but as this is an enum const, even though I put every attributes as UTF-8, nothing could get that STRING is what Eclipse should look for. But it still looks for STRİNG and it can't find and I can't use that. What must I do for that?
Project > Properties > Resouce > Text file encoding is UTF-8 now. Problem keeps.
EDIT: More information may give some clues which I can't get;
I am working on OrientDB. This is my first attempt, so I don't know if the problem could be on OrientDB packages. But I am using many other libs, I have never seen such a problem. There is a OType enum in this package, and I am only trying to connect to the database.
String url = "local:database";
ODatabaseObjectTx db = new ODatabaseObjectTx(url).
Person person = new Person("John");
db.save(person);
db.close();
There is no more code I use yet. Database created but then I get the java.lang.IllegalArgumentException:

Here is OType class: http://code.google.com/p/orient/source/browse/trunk/core/src/main/java/com/orientechnologies/orient/core/metadata/schema/OType.java
And other class; OCommandExecutorSQLCreateProperty:
http://code.google.com/p/orient/source/browse/trunk/core/src/main/java/com/orientechnologies/orient/core/sql/OCommandExecutorSQLCreateProperty.java
Line 81 says: type = OType.valueOf(word.toString());
Am I correct to assume you are running this program using a turkish locale? Then it seems the bug is in line 118 of OCommandExecutorSQLCreateProperty:
linkedType = OType.valueOf(linked.toUpperCase());
You would have to specify the Locale whose upper casing rules should be used, probably Locale.ENGLISH as the parameter to toUpperCase.
This problem is related to your database connection. Presumably, there's a string in OrientDB somewhere, and you are reading it, and then trying to use it to select a member of the enum.
I'm assuming in the code that you posted that the variable word comes from data in the database. If it comes from somewhere else, then the problem is the 'somewhere else'. If OrientDB, for some strange reason, returns 'STRİNG' as metadata to tell you the type of something, then that is indeed a defect in OrientDB.
If that string actually contains a İ, then no Eclipse setting will have any effect on the results. You will have to write code to normalize İ to I.
If you dump out the contents of 'word' as a sequence of hex values for the chars of the string, I think you'll see your İ staring right at you. You have to change what's in the DB to have a plain old I.
Unfortunately, it is related with regional setting, locale of your OS which is Turkish.
Two work around options :
1. Change your regional settings to English-US
2. Give encoding to the jvm as command line param for setting locale to English

One work-around is to type Type.ST and then press Ctrl-space. Eclipse should auto-complete the variable name without you having to figure out how to enter a dotless capital I on a Turkish keyboard. :)
