Java Program to Convert OutputStream to String

To understand this example, you should have the knowledge of the following Java programming topics:

Example: Convert OutputStream to String


public class OutputStreamString {

    public static void main(String[] args) throws IOException {

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        String line = "Hello there!";

        String finalString = new String(stream.toByteArray());



Hello there!

In the above program, we've created an OutputStream based on the given string line. This is done using stream's write() method.

Then, we simply convert the OutputStream to finalString using String's constructor which takes byte array. For this, we use stream's toByteArray() method.
