StringWriter Class getBuffer() method

• getBuffer() method is available in java.io package.
• getBuffer() method is used to get the StringBuffer that holds the present buffer value.
• getBuffer() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• getBuffer() method does not throw an exception at the time of returning StringBuffer.

Syntax:

    public StringBuffer getBuffer();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is StringBuffer, it returns the StringBuffer itself that holds the current buffer value.

Example:

// Java program to demonstrate the example 
// of StringBuffer getBuffer() method of StringWriter

import java.io.*;

public class GetBufferOfFSW {
    public static void main(String[] args) throws Exception {
        StringWriter str_w = null;
        String str = "Java World!!!";

        try {
            // Instantiates StringWriter
            str_w = new StringWriter();

            str_w.write(str);

            // By using getBuffer() method is to
            // get the buffer of this str_w stream
            StringBuffer str_b = str_w.getBuffer();
            System.out.println("str_w.getBuffer(): " + str_b);
        } catch (Exception ex) {
            System.out.println(ex.toString());
        } finally {
            // with the help of this block is to
            // free all necessary resources linked
            // with the stream
            if (str_w != null) {
                str_w.close();
            }
        }
    }
}

Output

str_w.getBuffer(): Java World!!!
