Java.io.ByteArrayOutputStream.toString() Method

Description

The java.io.ByteArrayOutputStream.toString(String charsetName) method converts the stream's contents using the specified charsetName. The malformed-input and unmappable-character sequences are replaced by the default replacement string for the platform's default character set.

Declaration

Following is the declaration for java.io.ByteArrayOutputStream.toString(String charsetName) method:

public String toString(String charsetName)

Parameters

• charsetName -- The name of supported charset

Return Value

This method returns string decoded from the buffer's contents.

Exception

• UnsupportedEncodingException -- If the charset name is not supported.

Example

The following example shows the usage of java.io.ByteArrayOutputStream.toString(String charsetName) method.

package com.tutorialspoint;

import java.io.ByteArrayOutputStream;
import java.io.IOException;

public class ByteArrayOutputStreamDemo {
   public static void main(String[] args) throws IOException {
      
      String str = "";
      
      byte[] bs = {65, 66, 67, 68, 69};
      ByteArrayOutputStream baos = null;
      
      try{

         // create new ByteArrayOutputStream
         baos = new ByteArrayOutputStream();
      
         // write byte array to the output stream
         baos.write(bs);
         
         // converts buffers content using Cp1047 character set
         str = baos.toString("Cp1047");
         System.out.println(str);
         
         // converts buffers contents using UTF-8 character set
         str = baos.toString("UTF-8");
         System.out.println(str);
         
      }catch(Exception e){

         // if I/O error occurs
         e.printStackTrace();
      }finally{
         if(baos!=null)
            baos.close();
      }   
   }
}
