Document

Creates a buffering character-input stream that uses a default-sized input buffer.

Usage

From source file:Main.java

public static void main(String[] arg) throws Exception {
    BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
    while (true) {
        String sLine = bf.readLine();
        System.out.println("::" + sLine);
    }//  ww  w . j av a2s  . com
}
