Método StringWriter getBuffer() en Java con ejemplos

El método getBuffer() de la clase StringWriter en Java se usa para obtener la representación StringBuffer de esta instancia de StringWriter. Este método no acepta ningún parámetro y devuelve el valor StringBuffer requerido . 

Sintaxis:

public StringBuffer getBuffer()

Parámetros: Este método acepta no acepta ningún parámetro. 

Valor devuelto: este método devuelve un valor de StringBuffer que es la representación de StringBuffer de la instancia de StringWriter. 

Los siguientes métodos ilustran el funcionamiento del método getBuffer(): 

Programa 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 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);
        }
    }
}

StringBuffer representation: GeeksForGeeks

Programa 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 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);
        }
    }
}
