Output:

StringBuffer representation: GeeksForGeeks

Program 2:

Java

// Java program to demonstrate // StringWriter getBuffer() method import java.io.*; class GFG {  public static void main(String[] args)  {  try {  // Create a StringWriter instance  StringWriter writer  = new StringWriter();  // Get the String  // to be written in the stream  String string = &quot;GFG&quot;;  // Write the string  // to this writer using write() method  writer.write(string);  // Get the StringBuffer of this StringWriter  StringBuffer stringBuffer = writer.getBuffer();  System.out.println(&quot;StringBuffer representation: &quot;  + stringBuffer);  }  catch (Exception e) {  System.out.println(e);  }  } }
