CharArrayWriter toCharArray() method in Java with examples

The toCharArray() method of the CharArrayWriter class in Java returns a copy of the input data.
Syntax: 

public char[] toCharArray()

Parameters: This method does not accept any parameter.
Return Value: This method returns a copy of the input data. 
Below program illustrate the above method: 
Program 1:

Java

// Java program to illustrate
// the toCharArray() method

import java.io.*;

public class GFG {
    public static void main(String[] args)
        throws IOException
    {

        // Initializing String Writer
        CharArrayWriter geek_writer1
            = new CharArrayWriter();

        char[] Sw = { 'G', 'E', 'E', 'K', 'S' };

        for (char c : Sw) {

            // Use of append(char Sw) :
            geek_writer1.append(c);
        }

        // Use of toCharArray() :
        char[] toChar1 = geek_writer1.toCharArray();

        for (char c1 : toChar1) {
            System.out.println("toCharArray : " + c1);
        }
    }
}

Output:

toCharArray : G
toCharArray : E
toCharArray : E
toCharArray : K
toCharArray : S

Program 2:

Java

// Java program to illustrate
// the toCharArray() method

import java.io.*;

public class GFG {
    public static void main(String[] args)
        throws IOException
    {

        // Initializing String Writer
        CharArrayWriter geek_writer1
            = new CharArrayWriter();

        char[] Sw = { 'G', 'O', 'P', 'A',
                      'L', 'D', 'A', 'V', 'E' };

        for (char c : Sw) {
            // Use of append(char Sw) :
            geek_writer1.append(c);
        }

        // Use of toCharArray() :
        char[] toChar1 = geek_writer1.toCharArray();

        for (char c1 : toChar1) {
            System.out.println("toCharArray : " + c1);
        }
    }
}

Output:

toCharArray : G
toCharArray : O
toCharArray : P
toCharArray : A
toCharArray : L
toCharArray : D
toCharArray : A
toCharArray : V
toCharArray : E
