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() methodimport 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() methodimport 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
