PrintStream write(byte[], int, int) method in Java with Examples
  • Last Updated : 29 Jan, 2019

The write(byte[], int, int) method of PrintStream Class in Java is used to write a specified portion of the specified byteacter array on the stream. This byteacter array is taken as a parameter. The starting index and length of byteacters to be written are also taken as parameters.

Syntax:

public void write(byte[] byteArray, int startingIndex, int lengthOfCharArray)

Parameters: This method accepts three mandatory parameters:

  • byteArray which is the byteacter array to be written in the Stream.
  • startingIndex which is the starting index from which the portion of byteacter is to taken.
  • lengthOfCharArray which is the length of byteacters to be written on the stream.

Return Value: This method do not returns any value.



Below methods illustrates the working of write(byte[], int, int) method:

Program 1:




// Java program to demonstrate
// PrintStream write(byte[], int, int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintStream instance
            PrintStream stream
                = new PrintStream(System.out);
  
            // Get the byteacter array
            // to be written in the stream
            byte[] byteArray = { 65, 66, 67 };
  
            // Get the starting index
            int startingIndex = 0;
  
            // Get the length of byte
            int lengthOfCharArray = 1;
  
            // Write the portion of the byteArray
            // to this stream using write() method
            // This will put the byteArray in the stream
            // till it is printed on the console
            stream.write(byteArray,
                         startingIndex,
                         lengthOfCharArray);
  
            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:
A

Program 2:




// Java program to demonstrate
// PrintStream write(byte[], int, int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintStream instance
            PrintStream stream
                = new PrintStream(System.out);
  
            // Get the byteacter array
            // to be written in the stream
            byte[] byteArray = { 97, 98, 99 };
  
            // Get the starting index
            int startingIndex = 2;
  
            // Get the length of byte
            int lengthOfCharArray = 1;
  
            // Write the portion of the byteArray
            // to this stream using write() method
            // This will put the byteArray in the stream
            // till it is printed on the console
            stream.write(byteArray,
                         startingIndex,
                         lengthOfCharArray);
  
            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:
c
