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 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);
}
}
}
// 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 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);
}
}
}
// 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
