StringWriter Example

suggest change

Java StringWriter class is a character stream that collects output from string buffer, which can be used to construct a string.

The StringWriter class extends the Writer class.

In StringWriter class, system resources like network sockets and files are not used, therefore closing the StringWriter is not necessary.

import java.io.*;  
public class StringWriterDemo {  
    public static void main(String[] args) throws IOException {  
        char[] ary = new char[1024];  
        StringWriter writer = new StringWriter();  
        FileInputStream input = null;  
        BufferedReader buffer = null;  
        input = new FileInputStream("c://stringwriter.txt");  
        buffer = new BufferedReader(new InputStreamReader(input, "UTF-8"));  
        int x;  
        while ((x = buffer.read(ary)) != -1) {  
                   writer.write(ary, 0, x);  
        }  
        System.out.println(writer.toString());        
        writer.close();  
        buffer.close();  
    }  
}

The above example helps us to know simple example of StringWriter using BufferedReader to read file data from the stream.
