Return value:

Example:

// Java program to demonstrate the example 
// of String toString() method of StringWriter

import java.io.*;

public class ToStringOfFSW {
    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 toString() method is to
            // represent the stream as a string
            String s = str_w.toString();
            System.out.println("str_w.toString(): " + s);
        } 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();
            }
        }
    }
