  • Last Updated : 31 Jan, 2019

The getBuffer() method of StringWriter Class in Java is used to get the StringBuffer representation of this StringWriter instance. This method does not accepts any parameter and returns the required StringBuffer value.

Syntax:

public StringBuffer getBuffer()

Parameters: This method accepts does not accepts any parameter.

Return Value: This method returns a StringBuffer value which is the StringBuffer representation of the StringWriter instance.

Below methods illustrates the working of getBuffer() method:



Program 1:




// 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 = "GeeksForGeeks";
  
            // Write the the string
            // to this writer using write() method
            writer.write(string);
  
            // Get the StringBuffer of this StringWriter
            StringBuffer stringBuffer = writer.getBuffer();
  
            System.out.println("StringBuffer representation: "
                               + stringBuffer);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:
StringBuffer representation: GeeksForGeeks

Program 2:




// 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 = "GFG";
  
            // Write the the string
            // to this writer using write() method
            writer.write(string);
  
            // Get the StringBuffer of this StringWriter
            StringBuffer stringBuffer = writer.getBuffer();
  
            System.out.println("StringBuffer representation: "
                               + stringBuffer);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:
StringBuffer representation: GFG
