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
