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
// 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);
}
}
} |
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 = "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);
}
}
} |
Output:
StringBuffer representation: GFG
