Capturing audio in Android

By Oleg Mazurashu,on March 17th,2010

In this post I am going to show how to capture audio in Android. Android allows to capture audio in very easy manner. But today I spent 3 hours for creating working example. I don’t know why I spent so much time,maybe because it is first time when I tried to work with multimedia . . . →Read More:Capturing audio in Android

Multitargeting output streams in Java

By Oleg Mazurashu,on March 15th,2010

I want to show how I implemented filter output stream that send data to multiple underlying streams. It is very easy. I need output stream for this

Using PushBackInputStream in Java

By Oleg Mazurashu,on March 15th,2010

The PushbackInputStream class provides a pushback buffer so a program can “unread”bytes. In other words,it can add bytes to the stream and then read them. This class allows to add data to the stream while they’re reading it. The next time data is read from the stream,the unread bytes are reread. Example:

Using buffered streams in Java

By Oleg Mazurashu,on March 15th,2010

Buffered input streams read more data than they initially need into a buffer (an internal array of bytes). When one of the stream’s read() methods is invoked,data is removed from the buffer rather than from the underlying stream. When the buffer runs out of data,the buffered stream refills its buffer from the underlying . . . →Read More:Using buffered streams in Java

Using Filter Streams in Java

By Oleg Mazurashu,on March 15th,2010

Filter input streams read data from a preexisting input stream such as a FileInputStream and have an opportunity to work with or change the data before it is delivered to the client program. Filter output streams write data to a preexisting output stream such as a FileOutputStream and have an opportunity to work with or . . . →Read More:Using Filter Streams in Java

Using URLConnection in Java

By Oleg Mazurashu,on March 8th,2010

URLConnections are closely related to URLs. Indeed,you get a reference to a URLConnection by using the openConnection() method of an URL object. In many ways,the URL class is only a wrapper around the URLConnection class. URLConnections provide more control over the communication between the client and the server. In particular,URLConnections provide not . . . →Read More:Using URLConnection in Java

Using URL in Java

By Oleg Mazurashu,on March 1st,2010

Here I am going to show example which works with URL. Each URL(Uniform Resource Locator) unambiguously identifies the location of a resource on the Internet. Example shows how to connect to an URL,download its data and show it in console via System.out
