问题 I have a scenario where I will get a large data as an input stream, which is going to have a delimiter and split it and process them.

Right now I am achieving this with the help of scanner as shown below , in the code: package chap5_questions; import java.util.Scanner; public class paintjob_chp5 { import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; public class ScannerTest { public static

Java, Telnet, check for String in an InputStream

别来无恙 提交于 2019-12-11 03:31:24
问题 I am fairly raw. I am trying to write a Java class to interact with Telnet. I saw that Apache Commons and Jsacpe had APIs. I am using Jscape's Sinetfactory. The Telnet I am connecting to sends a prompt to enter 'User name?:' as soon as telnet.connect() occurs. I am required to verify that this prompt is actually happening so I do not just write the answer when something else may happen. I am inexperienced with this and am sure there is a simple answer, just wondering if anyone might be able

问题 Following is a part of the code snippet that I will be using for my project. public String fetchFromStream() { try { int charVal; StringBuffer sb = new StringBuffer(); while((charVal = inputStream.read()) > 0) { sb.append((char)charVal); } return sb.toString(); } catch (Exception e) { m_log.error("readUntil(..) : " + e.getMessage()); return null; } finally { System.out.println("<<<<<<<<<<<<<<<<<<<<<< Called >>>>>>>>>>>>>>>>>>>>>>>>>>>"); } } Initially the while loop start working pretty fine.

Is it possible to capture the playing audio with Java?

问题 I was wondering if it's possible to capture playing audio on the audio output hardware with a simple Java program, and then write it to an outputstream for example. Is it? 回答1: If your desire is to record the output of all programs to a given audio device using a java app, like audiohijackpro, the short answer is no, this is not possible without native code. It is, in fact, quite difficult to do in any language. As far as I know, no platform makes this easy. On some environments, there is a

writing to OutputStream having capacity restriction

二次信任 提交于 2019-12-10 22:45:48
问题 Following the question I asked before: I am implementing an ByteArrayOutputStream having capacity restriction. My main limitation is an amount of available memory. So having such stream os : When I write more than say 1MB to the output stream I need to "stop". I prefer not throw exception but write the complete contents of os output stream to the specified other output stream argument. OutputStream out; os.writeTo(out); And after that continue the writings to os from its beginning In order to

Setting Content Type in Java HttpServer response

血红的双手。 提交于 2019-12-10 17:36:20
问题 I have a java echo httpserver up. It works with test sites, but the client code I'm working with fails to get the data. The server works perfectly with https://www.hurl.it/ The client works perfectly with https://requestb.in/ and http://httpbin.org/post When combining the two I get a response with a status code of 200, but no metadata / body content shows up in the client even though it's being sent. My only guess is because the content type isn't included, the client might be picky about

Based on answers here and here I came up the following method to get an input stream from an output stream: private PipedInputStream getInputStream(ByteArrayOutputStream outputStream) throws InterruptedException { PipedInputStream pipedInStream = new PipedInputStream(); Thread

Writing to Windows CMD from Java

允我心安 提交于 2019-12-10 11:56:25
问题 I'm trying to be able to input commands into the command prompt on Windows from Java. I use processBuilder, open the command prompt, and get the output stream, but when I try to write to that, nothing seems to happen. Do I need to include something else, or am I going about this all wrong? I know that I can pass arguments including commands into the command prompt when I initially start it, but my goal is to be able to open the window first , then interact with it second , not at the same
