The first line contains two space-separated integers and , the number of nodes and edges in the graph. Each of the next lines contains two space-separated integers and , the nodes connected by an edge.

BufferedWriter class writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. The buffer size may be specified, or the default size may be accepted. The default is large enough for most purposes. Python BufferedWriter - 9 examples found. These are the top rated real world Python examples of javaio.BufferedWriter extracted from open source projects. You can rate examples to help us improve the quality of examples. 1) Using FileWriter and BufferedWriter: In this approach we will be having the content in one of more Strings and we will be appending those Strings to the file. The file can be appended using FileWriter alone however using BufferedWriter improves the performance as it maintains a buffer.

Without a BufferedWriter this could make 200 (2 * 100) system calls and writes to disk which is inefficient. With a BufferedWriter, these can all be buffered together and as the default buffer size is 8192 characters this become just 1 system call to write.
