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
