参数:此方法接受不接受任何参数。


返回值:此方法返回一个StringBuffer值,它是StringWriter实例的StringBuffer表示形式。

下面的方法说明了getBuffer()方法的用法方式:

示例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); 
        } 
    } 
}
输出:
StringBuffer representation: GeeksForGeeks

示例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); 
        } 
    } 
}
输出:
StringBuffer representation: GFG
