bufferedinputstream

问题 I need to read zero-terminated strings from InputStream in Java. Is there similar to BufferedReader.readLine() method for reading zero-terminated strings? 回答1: No. Java doesn't recognise a zero-terminated string as such. You'll have to read the InputStream and look for a 0 byte. Note that this doesn't address the issue of character-encoding. The InputStream will give you the stream of bytes, and you'll then have to encode to characters via a Reader . If you have a multi-byte character

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I always get confused when to process my input data how, which process. Different times i find different solutions. I am also not clear about their Hierarchy. 回答1: InputStream is parent class of all input streams and readers. Classes that have Stream keyword will work with bytes

问题 Hi guys. I have a problem when downloading large size images.It's very strange, while read bytes from stream always no response. My code is as follows, any suggestion is welcome. public class ImageTestActivity extends Activity { public static final int IMAGE_BUFFER_SIZE = 8*1024; public static final int MAX_REQUEST_WIDTH = 480; public static final int MAX_REQUEST_HEIGHT = 480; private static final String TAG = ImageTestActivity.class.getSimpleName(); private static final int HTTP_CONNECT

问题 To start with, I understand the concept of buffering as a wrapper around, for instance, FileInuptStream to act as a temporary container for contents read(lets take read scenario) from an underlying stream, in this case - FileInputStream . Say, there are 100 bytes to read from a stream(file as a source). Without buffering, code( read method of BufferedInputStream ) has to make 100 reads(one byte at a time). With buffering, depending on buffer size, code makes <= 100 reads. Lets assume buffer

问题 To get user input in Java which is the better method? reader = new BufferedReader(new InputStreamReader(System.in)); or by use of Console--> Console c = System.console(); what is the difference between the two and which one is to be used. Or is there any other better method other than these two? 回答1: Console was introduced recently to Java (Java 6) to make reading and writing to the command line easier. Therefore, I would use Console. 回答2: I suggest you Scanner class to get user input from

问题 I'm working on a project where the url sometimes can have empty spaces in it (not always) example: www.google.com/ example/test.jpg and sometimes www.google.com/example/test.jpg. My code: try { URL url = new URL(stringURL); URLConnection conexion = url.openConnection(); conexion.connect(); // downlod the file InputStream input = new BufferedInputStream(url.openStream(), 8192); OutputStream output = new FileOutputStream(fullPath.toString()); byte data[] = new byte[1024]; while ((count = input

问题 After being confused about how to do so (as can be seen here and here, I am now successfully connecting to my server app and the appropriate RESTful method with this code: public void onFetchBtnClicked(View v){ if(v.getId() == R.id.FetchBtn){ Toast.makeText(getApplicationContext(), "You mashed the button, dude.", Toast.LENGTH_SHORT).show(); new CallAPI().execute("http://10.0.2.2:28642/api/Departments/GetCount?serialNum=4242"); } } public static class CallAPI extends AsyncTask<String, String,

问题 I'm using Java's BufferedInputStream class to read bytes sent to a socket. The data to the socket is HTTP form so generally is a header with defined content-length, then some content. The problem I'm having is that sometimes BufferedInputStream.read() will not read the full amount of data sent to it. It returns the number of bytes read but this is much less than has been sent. I have verified the bytes sent with Wireshark and can confirm the full message is being transmitted.) Sample code

问题 I've been doing some research for a blog post regarding java.io.BufferedInputStream and buffers. Apparently, over the years, the default has grown from a measly 512 bytes to 8192 bytes as of (presumptuously) Sun's Java 7 implementation, and was even explicitly specified in the JavaDocs in JDK 1.1.8. My question has also brought up questions of who/what deciedes what the default should be--it's not as black-n-white as I had expected. I am curious as to what the default buffer size has been at

问题 I'm fairly new to android and PHP programming and I am currently running into a problem printing my echo statement from my php page, which is as simple as: <?php echo "Hey there response!"; ?> What I am currently using in my MainActivity is: setContentView(R.layout.activity_main); TextView txtView = (TextView) findViewById(R.id.txt); //ASYNC WAY new GetData(txtView).execute(""); Where AsyncTask is defined by: private class GetData extends AsyncTask<String, Void, String>{ private TextView
