The write(char[], int, int) method of Writer Class in Java is used to write a specified portion of the specified character array on the writer. 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 writer.
- 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 writer.
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// Writer write(char[], int, int) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a Writer instance Writer writer = new PrintWriter(System.out); // Get the character array // to be written in the writer char[] charArray = { 65, 66, 67 }; // Get the starting index int startingIndex = 0; // 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 writer // till it is printed on the console writer.write(charArray, startingIndex, lengthOfCharArray); writer.flush(); } catch (Exception e) { System.out.println(e); } }} |
Output:
A
Program 2:
// Java program to demonstrate// Writer write(char[], int, int) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a Writer instance Writer writer = new PrintWriter(System.out); // Get the character array // to be written in the writer char[] charArray = { 97, 98, 99 }; // 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 writer // till it is printed on the console writer.write(charArray, startingIndex, lengthOfCharArray); writer.flush(); } catch (Exception e) { System.out.println(e); } }} |
Output:
c
