I am getting byte stream as below. These looks like UTF 8 bytes
3C524F4F543E3C535452494E473E54455354204F4E4C5920535452494E473C2F535452494E473E3C2F524F4F543E
I want java code which will convert above bytes to string as shown below
<ROOT><STRING>TEST ONLY STRING</STRING></ROOT>
It's probably really obvious, like it usually is, but I can't figure out why I am getting these errors on multiple functions.
if (!client.lowMem) {
for (int l = this.onDemandFetcher.getVersionCount(2), i2 = 1; i2 < l; ++i2) {
if (this.onDemandFetcher.method569(i2)) {
this.onDemandFetcher.method563(1, 2, i2); //Error
[Code] ....
The error I get on this line of code is 'Custom may not have been initialized', but no matter what I do, the error sticks.
Custom.cacheIndex = (Custom.cacheIndex + 1) % 10;
final Custom Custom = Custom.cache[Custom.cacheIndex];
//^^^^^
I am reading a book on Java and we are at a point where it is explaining type conversion in expressions. One of the examples shared has a byte being multiplied by itself and then assigned back to itself ...
byte b;
b = 10;
b = (byte) (b * b);
this is all good and dandy (that is, the code functions properly).
However, I am confused why I need to typecast here! Without the cast, the compiler screams, "Type mismatch: cannot convert from int to byte." Yet I haven't converted to an int?? It appears there was an implicit conversion.
The final value, 100, is clearly within byte's range of -127 to +127 isn't it? So I am lost as to what is the issue here.

So I'm trying to make a program that plays an mp3 file after a timer reaches 0, but i keep receiving the error "could not create audio stream from input stream" the audio file is 3.44 MB and 00:03:45 minutes long if that's a problem
In this simple example, I print a byte array to String:
Java Code:
import java.io.UnsupportedEncodingException;
import java.nio.charset.Charset;
public class PrintByteArray {
public void print(){
System.out.println(Charset.defaultCharset());
byte[] arr = {1, 2, 3, 4};
[Code] ....
However, Eclipse prints out strange boxes, which I was unable to copy into this message.
It's supposed to print out the values of the bytes. What am I doing wrong?
I am trying to convert the double 4270571936.0000000000d to a hex string using Double.toHexString() and the answer I'm getting is 0x1.fd17834p31, what does p stands for?
The answer I'm expecting to get is 0x41efd17834000000 so not sure why it won't give me the correct answer?
The following floating point Double to hex calculator shows the write answer right Floating Point to Hex Converter
I want to conver String value into Integer, and I have this :
String timeInterval = tfInputTinter.getText();
Integer tint=(Integer.parseInt(timeInterval))*1000;
but when I put this second line, the conversion, the program stops to work. I tried also with Integer.valueOf(timeInterval) but again I had the same problem.
How I can convert a string into a character array without using toCharArray???

View Replies View RelatedI am working on a small brain teaser project where I am taking a string input from a Scanner, and turning into ascii. The problem comes into play when the string has a space in it, so if the question is what's your name? and you say Michael Jackson, Michael gets converted then Jackson becomes the answer to the next question, rather then the second portion of the current string.
This is an older version of what I'm doing currently, but it had the same basic problem with spaces.I will say I did my current version entirely different.
nner user_input = new Scanner (System.in);
//Creates a string
String favoriteFlick;
System.out.println("Enter the title of your favorite film?");
favoriteFlick = user_input.next();

I am working on a simple online chat program. I have build the server services and generally everything works smoothly.Now for the input area i use a JEditorPane as like the output message area. The reason of choosing JEditorPane is because i want to apply some CSS on future...
Now under the input message area there are two JButtons. One for attachments and other one for emoticons. Now i am trying to make a Popup Menu with all my Emoticons Images when someone click the JButton(emoticons). I was thinking about a JList inside a popupMenu but that kind of thing is mostly impossible i guess. Any way to automaticaly convert String to images for example when someone type in inputJEditor something like this :) or this :( to convert it to emoticon image ...
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000"

Is there an advantage in using byte instead of int beyond the space savings? In my program, I'll never need close to the max value of a byte, let alone int, so it seems like a waste to make my primitives ints.
View Replies View Relatedsoo, is there a way to (via sockets or something like that) connect to a stream via the streamers url (or just via anything) and then get the actual stream? like the images that keeps updating? so that i can display the images/stream on a jframe?
View Replies View RelatedFor every stream that we create for java i/o we write at the end in finally block
finally
{
if(is!=null)
{
is.close();
}
}
It works
my question is as per syntax in if (is!=null) this means that if is means stream contain some value then close it(!=null)
then how it in my opnion it should be like (in logical way)
if stream contain nothing then close it
if(is==null)
{
is.close();
}
I am confuse about working this line
Why when I do this:
System.out.println((byte) 99);
I still get: 99 ... not the hex representation of the byte!!
Why is that?
I need to send a byte array across a network. I know how to do this. (server->client)
byte[] myArray = new byte[]{0,1,2,3,4,5,6,7,8,9};
DataOutputStream.write(myArray);
... and I know how to receive it.
byte[] myArray = new byte[10];
DataInputStream.read(myArray);
When I send over one of these arrays, it ends up stopping storing values in the array when only about half the array is received, even though the array is sent from the server all at once. This results in the receiver's array, in this case, being something like {1,2,3,4,0,0,0,0,0,0}.
I can easily solve this - and already have - by simply adding a loop onto it and waiting for the bytes to all be received, as the method returns the amount of bytes actually read.
byte[] myArray = new byte[10];
int bytesRead = 0;
while( bytesRead < myArray.length) {
bytesRead += DataInputStream.read( myArray, bytesRead, myArray.length - bytesRead );
}
I am simply wondering if there is a better solution to this, as the current solution isn't that elegant. Did I do something wrong to cause only a part of the array to be sent first? Would it be better to use DataInputStream.readByte() to read off the bytes one by one rather than an array at once, and then store them in an array afterward? Would this cause a performance decrease as each byte is read individually? (I'm sending an array of several million bytes)
I am trying to make a function to tell me how to know if a byte is powered on or not but it must be through a mask depending on the position you send.
bool estaEncendido(char byte,int pos)
{
// byte = byte<<(7-pos) ;
//byte = byte>>(pos+1);
int mask=1;
int result =1;
for(pos=0; pos<8; pos++, mask <<=1)
[Code] ....
In the main should have been as well
System.out.print(estaEncendido(5/*000000101*/,2/*00000100*/));
/*00000101 */
/*00000100 &*/
/*00000100*/This ignition
I mean i need to access to two txt file at the same time so i did this in method:

I have the following
Java Code: list.stream().sorted((s, s1) -> s.getName().compareTo(s1.getName())).distinct(); mh_sh_highlight_all('java');

How can I do it?
My code runs correctly when i run the clients one after another without using threads.I am getting this following error when i run my multi-threaded server. When a server accepts a client connection, ClientHandler is the thread that handles that client.Exception in thread "main"

I have a Stream instace which produces values using an infinite Supplier (it supplies values taken from an electronic sensor -- so unless the battery is low, the sensor will provide "for ever").
The stream is processed by a Collector using Stream.collect() (e. g. imagine that the values from the sensor should be averaged; in fact what it does is a bit more compliacted maths).
The problem is that the collector does not produce a result but hangs up, as the supplier does never stop providing more sensor values.
So what I need is a limitation rule that stops the stream. While there is a Stream.limit(long) method, it actually does not solve my problem as in my case it is not practical to stop after a particular count, while I actually want to stop streaming when the sensor value exceeds a particular limit etc. (hence, voids an arbitrary rule).
To sum up, what I need is Stream.limit(Predicate), i. e. the stream will stopped once the predicate becomes true.
Unfortunately I did not find anything like that in JRE 8.
Is that planned for JRE 8.1 or JRE 9.0? Or is there a known (and sophisticated) workaround?
I am new to Android. I have byte array of size 10. I am passing the Decimal values (131 - 140) to byte array. But while printing I get Negative (-) values with decreasing order .
How can I get same value as positive values?
Or How can I store positive value e.g. 131 as byte array element.
Please not my requirement is array must be ByteArray only
I have a checksum function that is suppose to read IPV4 packet and return a short integer value. The IPV4 packets are stored in a byte array. I am having trouble storing the first 8 bits and second 8 bits of the short integer into the byte arrays especially when they have leading 1s. For example, if my checksum returns 5571 (binary = 0001 0101 1100 0011) The first 8 bits is suppose to represent 195 but when I try to assign a larger integer type to a btye the information gets sign extended. The 195 turns into -61. I tried using bit addition like array[10] = array[10] & 0xff, but the result remains the same.
public static short checksum(byte [] a, int length) {
short sum = 0;
long data;
int i = 0;
while(length > 1) {
data = (((a[i] << 8) & 0xff00) | ((a[i + 1]) & 0xff));
sum += data;
