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
