Examples of java.io.BufferedReader

java.io.BufferedReader
BufferedReader is a buffered character input reader. Buffering allows reading from character streams more efficiently. If the default size of the buffer is not practical, another size may be specified. Reading a character from a Reader class usually involves reading a character from its Stream or subsequent Reader. It is advisable to wrap a BufferedReader around those Readers whose read operations may have high latency. For example, the following code
```
 BufferedReader inReader = new BufferedReader(new FileReader("file.java")); 
```
will buffer input for the file file.java. @see BufferedWriter @since 1.1

     * @return length of the <code>CLOB</code> in characters

    public long length() throws SQLException {
      if (len == -1) {
        long length = 0;
        Reader r = new BufferedReader(getCharacterStream());
        try {
        while (r.read() != -1) {
          length++;
        }
      } catch (IOException e) {
        throw new SQLException(e);
      } finally {

          r.close();
        } catch (IOException e) {
