The writeTo() method of ByteArrayOutputStream class in Java is used to write the contents of this ByteArrayOutputStream to the specified OutputStream that is passed as the argument. In this method OutputStream is passed as a parameter and the ByteArrayOutputStream is copied to this OutputStream.
Syntax:
public void writeTo(OutputStream outputStr)
throws IOException
Parameters: This method accepts one parameter outputStr which represents the OutputStream to which the content of ByteArrayOutputStream is to be copied.
Return value: The method does not return any value.
Exceptions: This method throws IOException if an I/O error occurs.
Below programs illustrate writeTo() method in ByteArrayOutputStream class in IO package:
Program 1:
// Java program to illustrate// ByteArrayOutputStream writeTo() method import java.io.*; public class GFG { public static void main(String[] args) throws Exception { // Create byteArrayOutputStream ByteArrayOutputStream byteArrayOutStr = new ByteArrayOutputStream(); // Create byte array byte[] buf = { 71, 69, 69, 75, 83 }; // Create outputStream OutputStream outputStr = new ByteArrayOutputStream(); // Write byte array // to byteArrayOutputStream byteArrayOutStr.write(buf); // Copy byteArrayOutputStream // to OutputStream byteArrayOutStr.writeTo(outputStr); // Print the OutputStream System.out.println( outputStr.toString()); }} |
Output:
GEEKS
Program 2:
// Java program to illustrate// ByteArrayOutputStream writeTo() method import java.io.*; public class GFG { public static void main(String[] args) throws IOException { // Create byteArrayOutputStream ByteArrayOutputStream byteArrayOutStr = new ByteArrayOutputStream(); // Create byte array byte[] buf = { 71, 69, 69, 75, 83, 70, 79, 82, 71, 69, 69, 75, 83 }; // Create outputStream OutputStream outputStr = new ByteArrayOutputStream(); // Write byte array // to byteArrayOutputStream byteArrayOutStr.write(buf); // Copy byteArrayOutputStream // to OutputStream byteArrayOutStr.writeTo(outputStr); // Print the OutputStream System.out.println( outputStr.toString()); }} |
Output:
GEEKSFORGEEKS
