The
StringWriter class is a subclass of the Writer class that writes strings to the output stream. To write a string, the character stream collects the string into a string buffer and then constructs a string. StringWriter's buffer grows automatically based on data. The important methods of the StringWriter class are write(), append(), getBuffer(), flush() and close(). p>
public class StringWriter extends Writer
import java.io.*;
public class StringWriterTest {
public static void main(String args[]) {
String str = "Welcome to Tutorials Point";
try {
StringWriter sw = new StringWriter();
sw.write(str);
StringBuffer sb = new StringBuffer();
sb = sw.getBuffer();
System.out.println("StringBuffer: "+ sb);
System.out.println("String written by StringWriter: "+ sw);
sw.close();
} catch (IOException ioe) {
System.out.println(ioe);
}
}
