The write(char[], int, int) method of PrintWriter Class in Java is used to write a specified portion of the specified character array on the stream. This character array is taken as a parameter. The starting index and length of characters to be written are also taken as parameters.
Syntax:
public void write(char[] charArray, int startingIndex, int lengthOfCharArray)
Parameters: This method accepts three mandatory parameters:
- charArray which is the character array to be written in the Stream.
- startingIndex which is the starting index from which the portion of character is to taken.
- lengthOfCharArray which is the length of characters to be written on the stream.
Return Value: This method do not returns any value.
Below methods illustrates the working of write(char[], int, int) method:
Program 1:
// Java program to demonstrate// PrintWriter write(char[], int, int) method  import java.io.*;  class GFG {    public static void main(String[] args)    {          try {              // Create a PrintWriter instance            PrintWriter writer                = new PrintWriter(System.out);              // Get the character array            // to be written in the stream            char[] charArray = { 'G', 'e', 'e', 'k', 's',                                 'F', 'o', 'r',                                 'G', 'e', 'e', 'k', 's' };              // Get the starting index            int startingIndex = 0;              // Get the length of char            int lengthOfCharArray = 5;              // Write the portion of the charArray            // to this writer using write() method            // This will put the charArray in the stream            // till it is printed on the console            writer.write(charArray,                         startingIndex,                         lengthOfCharArray);              writer.flush();        }        catch (Exception e) {            System.out.println(e);        }    }} |
Output:
Geeks
Program 2:
// Java program to demonstrate// PrintWriter write(char[], int, int) method  import java.io.*;  class GFG {    public static void main(String[] args)    {          try {              // Create a PrintWriter instance            PrintWriter writer                = new PrintWriter(System.out);              // Get the character array            // to be written in the stream            char[] charArray = { 'G', 'F', 'G' };              // Get the starting index            int startingIndex = 2;              // Get the length of char            int lengthOfCharArray = 1;              // Write the portion of the charArray            // to this writer using write() method            // This will put the charArray in the stream            // till it is printed on the console            writer.write(charArray,                         startingIndex,                         lengthOfCharArray);              writer.flush();        }        catch (Exception e) {            System.out.println(e);        }    }} |
Output:
G
