The write(char[], int, int) method of StringWriter 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 does not returns any value.
Below programs illustrates the working of write(char[], int, int) method:
Program 1:
// Java program to demonstrate // StringWriter write(char[], int, int) method import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a StringWriter instance
StringWriter writer
= new StringWriter();
// 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);
System.out.println(writer.toString());
}
catch (Exception e) {
System.out.println(e);
}
}

Program 2:
// Java program to demonstrate // StringWriter write(char[], int, int) method import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a StringWriter instance
StringWriter writer
= new StringWriter();
// 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);
System.out.println(writer.toString());
}
catch (Exception e) {
System.out.println(e);
}
}
