Example: Convert OutputStream to String
import java.io.*;
public class OutputStreamString {
public static void main(String[] args) throws IOException {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
String line = "Hello there!";
stream.write(line.getBytes());
String finalString = new String(stream.toByteArray());
System.out.println(finalString);
}
}
Output
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.
