Java ByteArrayOutputStream toString() method

The toString() method of Java ByteArrayOutputStream class is used to convert the buffer's contents into a string by decoding the bytes using the named charset. The length of the new String is a function of the charset, and hence may not be equal to the length of the byte array.

Syntax:

Parameters:

charsetName - the name of a supported charset

Returns

The toString() method returns the String decoded from the buffer's contents.

Throws:

UnsupportedEncodingException - If the name charset is not supported.

Example 1

import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class Java ByteArrayOutputStreamToStringExample1 {
    public static void main(String[] args) throws IOException {
        byte bs []= { 65, 66, 67, 68, 69 };
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        baos.write(bs);
        String str = baos.toString("Cp1047");
        System.out.println(str);
        str = baos.toString("UTF-8");
        System.out.println(str);
    }
}

Example 2

import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class ByteArrayOutputStreamToStringExample2 {
    public static void main(String[] args) throws IOException {
        byte bs []= { 86,87,88,89,90 };
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        baos.write(bs);
        String str = baos.toString("Cp1047");
        System.out.println(str);
        str = baos.toString("UTF-8");
        System.out.println(str);

Java ByteArrayOutputStream toString() method

The toString() method of Java ByteArrayOutputStream class is used to convert the buffer?s contents into a string decoding bytes using the platform?s default character set.

This method transforms an object into a string. It is used to construct a string containing the information on an object that can be printed, and we can redefine it for a specific class.

Syntax:

Overrides

toString() method in class Object

Returns

The toString() method returns the string representation of the object.

Example 1

import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class JavaByteArrayOutputStreamToStringExample1 {
    public static void main(String[] args) throws IOException {
        byte[] bs = {86,87,88,89,90 };
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        baos.write(bs);
        String str = baos.toString();
        System.out.println(str);
    }
}

Output:

VWXYZ

Example 2

import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class JavaByteArrayOutputStreamToStringExample2 {
    public static void main(String[] args) throws IOException {
        byte[] bs = {75,76,77,78,79};
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        baos.write(bs);
        String str = baos.toString();
